Tubes Across Rapture :
Rapture's Pneumo would better make sense as an (originally) planned system, instead of a retrofitted/delayed til the 1956 10-year city anniversary system. We can fudge that as a 'completion date', with a much earlier 'partial' system being used. 
 
Actually such a system Fits earlier-tech Columbia-era even better ( Oops, those verkakte-artist's disconnected city bits - floating separately - interferes with SO MANY THINGS - so impractical BUT BUT BUT IT LOOKS AWESOMENESS .. DERRRRRP !!!!! ) (( Consider 'wires' in Columbia face the same issue, as does transport in general )) Perhaps instead you could have those floaty three-balloon things ( their Infinite BS dim Full-Stupid Rapture FlyBot regurgitation ) delivering stuff -- as well as Spying on you - as part of the Prophet's "Trust (But Verify)" Sin Patrols. 
--- --- ---
Who Ran The 'Post Office' In Rapture ?
Possibly a Private Company, who then ran the Pneumo/Jet Postal as well ( or perhaps a competing 'mail' system service ?? )
Letters still had to be delivered to residences. The Postal Station post boxes are less convenient to many people.

Pneumo Mail Tubes Are A Real World Thing 
I have the Rapture Pneumo System tubes being a good (large) size - a 14 inch diameter. There were real world systems with even larger tube size THE HAMBURG GRO-ROHRPOST 450 mm ( ~18 inch ) - Operational 1967 (being delayed) to 1983.
Such systems were made practical and created 1850s ( usually from a central telegraph office to important/bulk customers like stock exchanges ) big systems by 1880s existed for general mail.
First pneumo mail system in US Philadelphia, in 1893 -- 1893 !!! < ---- HOW COULD THEY MISS THIS ?????
http://www.douglas-self.com/MUSEUM/COMMS/pneumess/pneumess.htm
A pneumatic mail system is still in use in The Vatican ( a city state less than a square mile ) - a subject that probably had Comstock waking up in a cold sweat many nights ( "WE MUST CLOSE THE PNEUMATIC GAP !!!" )

Rapture's Pneumo System Should Have Been Part of the City From the First :
It Would (should) have been planned/built into the city's design (retrofitting is costly). Such systems existed in many of the World's big cities, since the turn of the century. ( Perhaps a partial system was built that way, and it took til 1956 to have a citywide system. )
1956 ( the plaque commemorating finishing it by Rapture's 10th anniversary ) then is a bit late, but perhaps that was the FINISHING of the AUTOMATIC system ( versus a mixed system/piecemeal private/manual system ). Early (real world) auto-routing systems had been a bit crude for a citywide automatic system to work ( so McClendon Robotics to the rescue ... )
--- --- ---
Rapture Mail - How It Worked Before the Jet Postal Was Operational :
Mailbox with manual pickup/delivery. Mail carried to Post Office, is sorted for various destinations.  Mail is transferred, sometimes with several intermediary sortings. Manual final delivery.  Special handling of various kinds.  Long distance transfers to communities outside Rapture City - Atlantic Express had the mail  contract for that.
Jet Postal Pneumo fully operational 1956 ( Dedication Plaques... seen in game )
Modern mail systems deliver to individual houses/businesses and there just are not that many 'Pneumo'
Kiosks ( certainly not in any of the individual apartments we saw ).  Rich people might have had them, but I  didn't spot any  ( auto-sorting into rows of individual mailboxes would be a typical system - cheaper per unit the larger the number of boxes ).
So there would still have to be mail carriers (mailmen) to deliver (and possibly pickup) mail the last stage  of the delivery path.   Items that were not machine addressed (numbers punched in at the Kiosk) would still have to be sorted by hand at centralized Post Offices ( though transported via 'Pneumo' ), and since that costs more there probably would be some kind of address marking scheme to allow some basic automatic routings. 
Many of the apartment buildings had even a Pneumo Kiosk within them  ( The Sinclair Deluxe did ).
--- --- ---
Early Pneumo (Despite that Plaque Commemorating the Jet Postal Finished 1956) :
Maybe at an earlier time there was only Partially-automatic delivery ( versus a mostly manual postal system ). The Real World had some Pneumo systems with a dialed-in destination coded ( only a few dozen combinations at most ) on contacts on the capsules, which the (real) Pneumo machinery would read ( with the capsule stopped ) and then electric switches/relays would shift/route the pathway mechanically to forward it to the appropriate coded destination ( multiple tubes outbound with potentially additional forwarding routers along the way ). In some systems, the canister/capsules were large enough to contain a small bundle of mail and magazines. The system won't work as seen in BS2 with mail whizzing by through transparent tube sections, or food cans shooting out of a broken Kiosk ( without Capsules things don't move properly with the airflow, and snag/bounce around get stuck/broken/damaged ).
Unless you had a Pneumo tube/kiosk in your house/business, it couldn't be fully automatic, and still required final manual sorting/delivery from local office/mail-carrier stations ... on foot to conventional mailboxes. In Rapture, individual mail items would need some address entered ( probably like a phone number entry at the Kiosk ) when sent ( no OCR zipcode readers yet in Rapture ). Payment for Postage likewise would have to be made somehow ( no stamp vending machines anywhere that I saw ). P.O. Boxes we saw at the Stations would be hand sorted ( as also was done into the pigeonhole shelves ). The Pneumo system still would cut out alot of time the mail sits waiting for sorting, or being bundled and transported in different directions manually via vehicles. Labor, of course, would be saved. Individual Kiosks could have 'direct' delivery to a waiting customer ( probably a phone order ) by arrangement of the sender ( some businesses with alot of traffic, like restaurants/shops/stores/newspapers, would have their own tube/kiosk to direct route that way ).
Later (perhaps what the 1956 date signified), computerizing/mechanizing the Pneumo would have improved much of its operation.
-
Zap Code : A 5 digit (100000 possible addresses) mailbox delivery number could be punched in at a Kiosk (cutting out the need for a Mailman to read addresses and then do the routing. A Coin Slot for the payment (a built-in weight scale).
Potentially could be using the same number as someones Telephone number.
--- --- ---
--- --- ---
Pneumo-Gram :
Unfortunately not that many people had their own private Jet Postal Station ( though there could be buzzer Alerts/Annunciators for 'Pneumo Station' based Mailboxes - auto-sorter stations ).
Might have been neat for most/many residences to have a smaller direct delivery Pneumo 'in-house' for letters ( larger packages would have to be picked up/hand delivered, or a Jet Postal Notice (punch card ??) to enter into your nearest Pneumo Kiosk to have the large item forwarded to you there ).
Upscale Residences would have this as a 'feature'.
WE Saw mailboxes outside of doors in Mercury Suites - even the 'Best and Brightest' didn't seem to have their own Pneumo Machine and their mail had to be hand delivered to their box ( which they had to open their front door to retrieve ).
In game E-mails (equivalent) would have their place to facilitate lots of other activities ( a perfect interaction for the 'off-line' tablet/smartphone part of the game).  Remember other media can be tied to these 'messages' offering a much expanded utility and interest generation.

Diagram of Jet Postal machinery
Jet Postal Detail (Sub-Station Sorting) :
We saw the smaller glass tubes (and letters whisking thru them) you see in some Jet Postal Pneumo substations (like at Atlantic Express Depot) which are too small for the real system's large transport tubes  ( The ones that move stuff using pneumatic canisters (12 x 12 x 24 inch capsules ?) long distances ).  Instead they  would be part of the Stations sorting device (which puts individual letters into the individual post-boxes).  Their mechanism would use high pressure air to move the individual letters/light packages, and could work  short distances ( heavier/large packages would be hand sorted from the canister bin ), and simple flapper actuator valves could guide the letters into the correct mailbox ( alot simpler/cheaper than the full-blown canister dumper mechanisms used at package routing Stations).   The individual loads would have to be  separated by intervals to keep them from jamming.  The short distance tubes would allow integral de-jamming  and cleaning systems.
The food cans and bottles we get out of that broken Pneumo pipe at AE Depot might possibly work with high enough pressure and air volume ( for a short distance ), but I would not count on how much damage they might suffer -- they would need a buffer to prevent them crashing violently into existing contents at each postal-box.  And the wear in the pneumatic tubes would be a costly a maintenance headache.
-
Because of its utility, there probably would be more than a few private Pneumo system in Rapture, it being a labor saving device.  In real life they were used to move paperwork around in businesses and even hospitals.
Persephone (the Prison) looked like it had its own restricted system.   New Rapture's City Hall would want a 'city' system back in operation, if not just in the City Center, but to all parts of City Limits.  Restoration outside that area  would be eventually done ( handy for sending loot home/to base ?? )  Needless to say that there would be a  need to isolate/regulate that outside traffic from New Rapture's internal system. ( Some jobs/Missions for the MMORPG there ... )

The Difference in Rapture was the highly-automated nature of ITS Pneumo System.

A Row of 4 Pneumo 'Tubes' in the Prison 'Mail Room' in Inner Persephone :
The Pneumo system is not a 'Tube-goes-to-only-one-Tube system' as the systems auto-routers allow bypassing manual sorting at a Postal Substation (Post Office).  So why 4 tubes here ? :
* A busy mail office would have a 'Pneumo' Capsule ejector machine that pushes an incoming capsule onto a rack ( and not just auto-dump the Capsules contents into a bin --- though that option could be arranged also ).
* One 'Tube' is sufficient for fast repeated sendings, and if needed an 'empty' magazine loader option could be added to a Deluxe Mailing Station ( one that includes auto-charging of the Postage, and punch-card or 'memory' register driven addressing. )
* That Prison Office location also has one of the dedication plaques Commemorating activation of the Jet Postal Pneumo system in 1956 on the 10 year anniversary of the founding of Rapture.
* Perhaps the Pneumo in Persephone is a 'closed system', with limited outside access - as in ONLY thru one 'outside' Tube in the Mail Room and the others 3 are for a dedicated/isolated system in sections of Inner/Outer Persephone ( like the Wardens Office ) to avoid the potential prison security problems of hacking/contraband.

Tubieswitchboard.jpg|Manual Routing
Unfortunately even if it 'looked neat' to have letters and things whizzing through the tubes (seen in BS2), it really cannot work that way, and a canister more like the (Minervas Den) "Air-tite Archives" systems HAS to be used to transport things.
The thing shown in the Infinite BS DLC ( TV-like things with lil T-Rex arms was just a bit too F@#ked up ... But I supposed it 'Looked Neat' to those last remaining designers and artists ).
A central mail routing station of a REAL Pneumo mail system. Many such systems had tubes only about 3 inches across ( for letter sized transport ). The problem with larger sizes was weight, and whichever size was chosen, there still would be countless packages that would not fit ( and could be subject to damage ). Some of these systems were built around a city's central telegraph office, and were used to send Telegrams between distributed substations ( for subsequent manual local distribution ).
Pneumo system existed in the real world, and this picture looks almost verbatim what they modeled in Minervas Den ( these canisters are a bit larger than existed on many systems where the tubes were only 2.5-3 inches across ).
Pneumo system in the US. Note how large the canisters are in this system. Tightly packed Bundles of mail being transported to distributed post offices for local delivery.
Most of the long distance Mail in the US went by Train ( which have central stations ).
--- --- ---
AGAIN Look at all that machinery and mechanisms a Proper Pneumo system needs to operate ...
Note that this was added approximately 10 years after the city was Founded - a system to enhance. 
The city structural layout should have been initially designed with space for upgrades and contingencies, so that later needed fixes could be done without MASSIVE rebuilding. Utility systems would be the most obvious place for such allowances ( being directly under central planning control from the start ). 'The Pneumo' would make use of those 'RESERVED' spaces to add its required mechanisms.
--- --- ---
How a Pneumo system works - Basic mechanism is an object propelled by a stream of air in one direction in a pipe(line).
Unfortunately the actual item ( letter or can of food ) flying along thru a tube doesn't quite work in the real world. A capsule container that fits closely inside the line/pipe/tube is needed for the air flow to properly carry it the distance.
The tubes usually travel point to point, and a more complicated machine is needed to change between tubes to be able to 'route' to differing destination. To be 'automatic' a mechanism is required that can 'label' a shipment to guide the routing logic (where to send the shipment...). By shifting the airflow, the same tube can be used to move objects in both directions.
Within a short time of its functioning ( Ryan Industries (?) finished installing the Pneumo system in 1956 ), the Pneumo was integrated with the Rapture Mail Service. A combination system allows Manual delivery - mail sent to post office for routing and delivery at mailboxes by postman.
Normal mailbox service - local deliveries - batches of mail sent to postman who makes hand delivery to local ordinary mailboxes. Mailman Bundles are commonly distributed via the Jet Postal ( as are letters the Postman picks up ).
--- --- ---
Cost - the system was simple enough that the machinery required were not expensive and the maintenance was low. This allowed operating at a profit with reasonably low mailing charge. Additional charges are made for extended service.
Moving mail/small packages using the Pneumo was very convenient, so was used with great frequency, which brought several expansions of the system.
* A Coin slot for mailing charges (sending/receiving and optional service). The Pneumo Box won't open until you pay ( helps prevent people using them as garbage cans ).
* Mailing Tokens - standard 'letter' postage that the Jet Postal system 'Pneumo tubes' accept in their coin slot. Stamps are also accepted for 'manually' processed mail (mail sent to 'POST-OFFICE').
* A built-in weight scale adjusts mailing charges for each shipment ( if over the standard 'letter' weight ). System will 'reject' if load is overweight.
Cargo size limits - ( maximum size - 14 x 14 x 20 inch, and weight limit ~ 20 lb ). There is a rejection/ejection mechanism for loads that exceed the limits ( and dimensionally if the capsule door wont close ).
--- --- ---
Addressing System :
* Dial entry ( like a telephone 6 digit ) Postal Code ( which includes all mailboxes in Rapture and all the Satellite sites/communities ). The numbering system includes a letter abbreviations for areas of Rapture in which each tube/mailbox is located. A magnetic tag is programmed into the capsule which is used by the system to direct and route to the destination.
* Many units had a built-in phone 'intercomm' for a customer directory service 
* an operator would look up a person/place in a directory and apply the correct code for the transfer ( this would require an additional charge ).
* Dialing a 'Receive' code for a postbox 
* Pneumo postboxes can be used for receiving mail as well as sending it (if the customer has paid for that service). Prearrangement would be made to 'hold' mail so that it could be 'forwarded' on demand.
Auto Sorting of mail - small loads ( like individual letters ) are consolidated at Substations automatically for forwarding long distance
Auto-sorting PO Boxes - a bank of mailboxes that the Pneumo delivers to and sorts incoming mail into the correct mailbox slot. ( Customer has to come to the PO BOX to pickup their mail ).
--- --- ---
Typical Pneumo Tube Usage Sequence :
* Press the MAILING button,
* Put in first coin, empty capsule arrives ( if not already present ),
* User opens door and fills compartment (capsule), an Indicator shows weight.
* User Closes door.
* User dials in the destination number (6-digits) or presses 'POST OFFICE' button for manual processing (extra fee).
* The remaining Charge is shown and user puts in any balance of coins.
* User presses GO button and the mailing is jetting on its way.
--- --- ---
Installations :
* Local Office - a mechanical (automatic) installation - a group of Pneumo Tube each send direct to their nearby 'Local Office'
** Individual Pneumo Boxes are each connected by a single 2-way line into a Pneumo Local Office, where the more complicated routing system is shared between numerous 'tube' mailboxes in an area. From there, the address tag is read and the Local Office routes the capsule appropriately (to another Local Office or to a central Substation).
* Jet Postal Substation - manned Postal station that processes manual mail(sorting), and has PO Boxes and other functions requiring a human. Serves as hub for transfer tubes, centralized air compressors and additional auto-routing control and monitoring equipment. There is at least one Substation per 'Plaza' hub.
* Jet Postal Central - Administration, billing, directory service, and complaint department, overflow handling.
* Lost-n-Found Warehouse - periodically a magnetic tag fails and there is no return address on the shipment. Some very interesting and sometimes embarrassing items have accumulated at the City's Jet Postal Lost-n-Found department.
--- --- ---
Equipment :
As with so many other things, people don't realize of how complex/large the whole mechanism is required to make a communication service actually work. All they see is the Pneumo-box or the Mailboxes and/or a counter at a Post office.
* 'Pneumo Tube' Post boxes - the mailing machines the public deals with.
* Capsules - designed to efficiently travel thru the tubes without jamming/gumming and to protect the cargo while making the high speed transits ( hitting 100 mph for long ranged transfers ). Capsules have a simple magnetic tag used for automatic routings.
* Piping - the 'Lines' :
** The sending end increases its air pressure and the receiving end introduces a vacuum. The capsule's seals make a near airtight fit which allows the force of the air to efficiently move the capsule to the other end. A slow spin is induced on the capsule to prevent uneven wear of the seals.
** Note the size of the 'line' tubes in the diagram - illustrates some of the 'stuff under the floors' that people don't realize about Raptures construction ( or that of any modern city ).
** Line Pipe is a standard 1/2 inch thick steel tubing ( long distance lines may use a stronger 1 inch thick steel - they may pass thru 'open ocean' with its crushing 280+ psi pressure ).
** The Pneumo line Pipes were made with removable liners ( inside the permanent structural pipe ), which could be easily extracted/replaced via accessible access points. This guaranteed a fully sealed and smooth passage and eliminated costly/difficult repairs for worn pipes.
** 'Local' Lines run between the Pneumo 'Tube' machines to a Local Office. They are at most a few hundred feet long.
** 'Transfer' Lines run between Local Office to Substations or direct routes to other Local Offices. They could be a thousand feet long and often ran in a large loop.
** 'Trunk' Lines run long distance between Substations ( generally one per 'Plaza' cluster ) that can be miles apart. These require higher pressures (and had more pipe volume because of their length to handle ). The capsules move through them at much higher speeds. For the longest trunks out to distant communities and industrial sites, repeater stations were used to push the mail capsules the required distance.
** As a single line tube can only handle traffic in one direction at a time, heavy traffic routes have a line in each direction. Low-traffic lines can use a single tube in which the flow direction is reversed at need. ( the two endpoints signal each other electrically as to which one wants to 'send' ).
* Compressors, Air & Vacuum pumps, Air Reservoirs - drive the capsules thru the lines/pipes by pressure differential. Air dryers to control moisture that can cause icing problems when large amounts of compressed air used. Vacuum Compensation chambers absorb the air impulse sent in along various 'lines' (more controlled valves and exhaust paths... tubes everywhere ... ).
* Control :
** Line pressure doors (sliding plates) that allow local airflow to precisely control a capsules movement into and out of the various machinery and queing tubes.
** LOTS of electrically controlled air valves ( much of the machinery is pneumatically actuated and relay logic controlled ).
** LOTS of air pressure sensors and 'feeler' mechanical contacts to act as sensors for the system logic.
** Communication lines between the various machines used to signal send/receive/status commands. The mechanisms were designed to use simple logic that did not require any fancy electronics and could if needed be controlled remotely by an operator. Audit tapes(paper) can record the address and movement signals of mail traffic.
** Routing address system - Magnetic Readers and Writers used for the addressing logic ( Magnetic Tags on the Capsules ), routing control logic and mechanism
** Auto-routers that make decisions for smart redundant path-routing, load leveling, and failure adaption ( manually programmed alternates ). Alot was based on phone system logic.
* Sorting :
** Sorting machines - addressed mail loads are dumped appropriately into sort bins, PO Boxes, forwarding Capsules.
** Sorting bins - Manual (Capsule's mail get auto-dumped into a bin) or Automatic content sifted into PO Box)
** Station PO Boxes ( for customers who prefer a separate destination for mail ).
** Holding Buffers - used for 'On-Request' deliveries ( user dials their ID and a mailing held in the central buffers is sent to the mailbox/Pneumo Tube the customer is at ). Similar to an 'indexing dry cleaning storage rack' that can cycle insert/retrieve from a continuous chain. Overflow could be handled by a central buffer located at the 'Central' office.
* 'Empty' Pneumo capsules 'Ammunition' magazines ( located at the Local Offices, Substations and Central site ). 'Empty capsules were kept handy so busy customers do not have to wait for their shipment to be sent off. Automatic Logic keeps a supply of 'empties' local and sends for more before they get depleted.
* Ordinary mailboxes which mailings can be manually delivered to (and picked-up from).
* Pressure Seal for the Pneumo 'lines' at Bulkheads :
** When a section of Rapture gets a pressure increase (major leak) it trips the automatic seals, and its bulkhead pressure seals close ( passageways, ventilation, Pneumo tubes all get closed off together - electric power and water do not and some 'hardened' utility 'mains' have their own independent seals ).
** A small automatic door closes off the Pneumo line pipes that pass thru the bulkhead ( with the usual Failsafe' double door mechanism that will seal even if a capsule blocks one of the doors ). The 'simple' Failsafe pressure seals are designed to require manual reopening once the problem is solved - closing/sealing reliably is the greatest concern.
* Isolation Valves - large pipe valves used to isolate line sections that have air leaks ( and act as backups to Bulkhead seals ). These can be remotely controlled.
* Substation components are modular allowing different combinations of equipment to meet the traffic and usage patterns of the location. Numbers of Trunk lines and area Local Offices varied as did the needs for Empty storage, On-Request Buffering, PO-Boxes, etc ... Local Offices were more standardized, and if needed multiples were placed to handle larger numbers of Pneumo 'Tubes' deployed.
--- ---
Redundancy on System Failure :
* A red light on the Pneumo Box would indicate that that Box was not operable.
* Busy areas had nearby Pneumo Boxes alternate between 2 (sometimes 3) different Local Offices, so that if there was a major failure, a nearby box was likely to still be working.
* Local Offices have more than one connected transfer line so that it can continue to operate if one is broken.
* Hand sorting can be done if an Auto-router is broken ( and the auto-router is double redundant itself )
* Manual delivery via manned stations can be done if a local system is completely broken ( fallback to the system used before Jet Postal was available ).
* The system had automatic failure reporting to speed improve repair time and keep the system available to customers.
* Failing long distance Trunk lines often have a second or even third parallel line. Trunk Single-line failures can be routed around via other trunks to other destinations ( a Substation has trunk lines running to multiple 'adjacent' hubs - never less than 3 ).
The Pneumo lines can be used to circulate air in an emergency when the primary air ventilation system (and its backups) have failed. Several locations in the 'ruins' are currently (MMORPG time) getting ALL of their fresh air this way.
Security - The Pneumo 'Tube' machine can have an optional 'hidden' camera that could be used in 'problem' locations where the Jet Postal was being used for illegal activities or suffered continuing vandalism. Plans to install gun turrets were never seriously considered, though hack/tampering 'shock' boobytraps and alarms were often installed.
---
More than a few companies purchased Pneumo equipment and ran their own in-house mailing system, which was convenient for transferring paperwork and small items within an office building or manufacturing company. Some private systems even had long-distance 'transfer' lines running between buildings and even to private residences. The Jet Postal company could be contracted to maintain the systems as an option.
A larger package-sized Pneumo system was being tested around the time of the start of the 'civil war' and was then never completed. The system would likely have only run between Substations due to the cost of laying down the much larger pipes the package-sized lines used. It was also thought that there would be too much competition from the existing Freight companies and the planned 'package-size' was too limiting.
Note - Pneumo Tube seen in the Smugglers Hideout in BS1 - how much contraband was simply 'mailed' to the smuggler's customers ???.
Later Pneumo Tube machines had a built-in system to forward the collected coins/tokens on to Jet Postal Administration (and to be tallied with recorded shipments). This cut down the frequency (and expense) of manual servicing and removed some temptation for hacking/vandalism-theft.
---
McClendon Robotics was contracted by Ryan to see if they could make a mini Security FlyBot which could fold to fit in the standard 14 x 14 x 20 inch Pneumo Capsule. Being able to quickly deploy Security Bots from Pneumo Tubes located throughout the City would be very useful. It is not known what the project achieved, or if it was even feasible ( it may have been decided to wait for the larger 'package' Pneumo system ). Inability to carry a sufficiently large gun or flamethrower may have been the issue.
---
After 'the fall' of Rapture we probably should have seen alot of Pneumo Capsules being used as containers all over the city ( handy size, close airtight, lightweight, strong, lots of them ). I was never really sure what those half-leather covered 'crates' we found so many of were supposed to originally be for.
Was anybody else ever reminded of Daleks when you first saw the Pneumo Kiosks/Tubes ???
--- --- ---
Air-Tite Archives - Send * Receive * Store,  Fast * Trusted * Secure :
Using the Pneumo to access from anywhere in Rapture ??   Many companies may have stored business records and other valuable archived information ( making it a treasure trove for the rebuilding City ).
Mass Capsule/Canisters storage and retrieval systemry at the facility - Minervas Den (in MMORPG) was one of the early parts of old Rapture to fall under New Rapture's control ( actually the place where it all started when Tenenbaum returned to The Thinker after he ill-fated episode on the Surface ).
MMORPG - What might the Player find in this place - A City Mission (for Players) to inventory a set of retrieved Capsules taken from the Storage, and using the info as clues for looking for useful resources for the City.
Frequently humorous things are to be found, when other things might more disturbing.  Others are just a sad commentary of the aspirations and ambitions of the people of Rapture ruined by miscreants like Fontaine and Lamb.
Yet another Asset for Player Creators ( the Asset Creation Community ) to exercise their creativity the many and varied contents of these long ago archived capsules ( lots of lost stories, etc ... ).
--- --- ---
One of the Broadway Department Stores in LA ( which had 9 floors ) around 1925. Each of the store's dozens of departments would process accounting through this central office ( processing customers Credit transactions likely also had something to do with it ).
Notice that the tubes look to take cylinders sized about 1 1/2 inch sized for receipts ( possibly for cash payment/change ? )
--- --- ---
Shopping via Pneumo :
Early in BS2 development, the developers planned the Pneumo to be part of a bartering system with NPCs. There would be a booth with a Pneumo, Radio, and TV with Camera. The Player would contact an item-dealer to buy/sell. The idea was later dropped ( heh, Delta couldn't really talk much - one "OOOORGH" for 'buy it' and two "OOOORGH" for 'pass' ... ).
Normal Rapture would likely have this system for some of its shopping ( their version of 'buy online' ). Other larger items could probably be purchased also with later manual delivery. With resumption of reliable Pneumo operation in New Rapture, the same kind of remote commerce will probably be set up again.
--- 
Fortunately there wouldn't be a Pneumo in Every Apartment to be same as Phones today - so to avoid subjecting the Citizens to Insidious/Pesky Phone Scammers and Junk Email Advertisements.
--- --- ---
 'Pneumo' Advertising Concept :
art pix ??
"Concept art shows a special branch of the Pneumo Lines (the BS:I Skyline clone) that catered to advertisements and/or news bulletins. Images would be projected onto the moving canvas. This special branch would have been indicated through slots lining the walls and floors, an entrance and exit, and may have zoomed past the Player's view."
'3D' objects moving by ... An Interesting idea that might work ( but we aren't having that badly-designed and redundant system in the MMORPG's Rapture ).
--- --- ---
Pneumo This Sucka !!! :
http://blog.modernmechanix.com/pneumatic-tubes-shoot-hot-meals-to-homes/
If only I could order from In & Out Burgers this way ...
SO little do most Players know that the 'Pneumo' is NOT an original idea, and its widespread used 100 years ago ( sending mail in some of the worlds great cities ) existed. We should have seen a system like this in Columbia (if they didn't want to be thought 'backward' for that Worlds Fair - and they did regurgitated nearly every other idea from Rapture, so why not this one too ?)
--- --- ---
Jet Postal Station in the Atlantic Express Depot still has Pneumo items visible going thru the tubes :
As late as 1968 parts of the Pneumo system are still working. The Long distance system would be down thru many routes due to floodings and other damage ( and general lack of maintenance ).
Numerous other Pneumo Mailbox machines have goodies in them ( you would think that such things would be long gone -- if they hadn't arrived more recently - Though who is doing the sending and who the receiving??? Resupply for the thugs sent after Delta ?? )
The Pneumo system was meant to be robust and easily repaired and was fairly new ( fully activated in 1956 ). So even with poor maintenance and neglect, it would likely keep operating (at least in parts of it) for a long time.
http://img853.imageshack.us/img853/3256/pneumo.png
Grace ( if you haven't killed her ) sends you stuff via Pneumo from Paupers Drop to Siren Alley. A pretty good distance to still have working ( including all the intermediary Jet Postal routing equipment -- 2 Local Offices and a Trunk Line ). When you are in Sirens Alley, Sinclair sends you useful stuff from Dionysus Park ( at the "1919" door lock ) - When apparently he isn't quite trapped in the train -- unless he has radio'd some minion to mail it to you from some other location.
For New Rapture, it only takes a little 'Rocket Science' ( or some old manuals ) to get their Pneumo systems working again and expand it as needed. Where there is a Will, there is a way... Automatic mail is a useful labor/time saving device. If the Pneumo doesn't yet work in YOUR neighborhood, then its up to YOU to do something to get it back in operation, which will earn you Prestige from the other Citizens.
