Iron Ore Mine East

Iron Ore Mine East is located in the Northeast corner of the map. It supplies iron ore in hoppers to be delivered to the Steel Mill. The mine also requires excavators on flatbed cars from the Machine Factory & Town.

The station is also able to service the S282 locomotive and has a repair station.

Service Point

Service Points are where locomotives are repaired and refueled. Depending on the location, service points can refuel diesel fuel, coal, water, and/or repair damage. Some locations also have separate coal and/or water towers for steam locomotives.

Servicing your own locomotive requires a license. If the player does not have the required license, service fees can be paid at the career manager. However, fees paid in this way cost twice as much, so the player is incentivized to purchase a manual license as soon as possible.

## Usage

Drive a locomotive into the service area. Once the locomotive is aligned, the service point will make a beeping sound, and the terminal will display the current damage and stock levels of any components or consumables the locomotive has. If the service point is a water tower, the horizontal position of the spout must also be aligned with the engine's water tank using a wheel at the tower's base.

If the player has a manual service license, the player can repair or restock the locomotive by pulling a lever for each item available at the terminal. If the player does not have enough money to pay for service, the levers can be pulled in the other direction until the price is at an acceptable level.

Repairs and consumables are not applied until the player uses their wallet at the terminal's point of sale. Once service is paid for, it cannot be removed from the locomotive.

Job validator

Career Manager and Job Validator

The job validator is used to accept jobs and validate completion of them, as well as dispensing payment. They can be found in every Station Office, next to a career manager. They have a tan exterior and are larger than the career manager. They have a matte black sign reading "JOB VALIDATOR" at the top, a printing slot, a "reprint active jobs" button, a job booklet insertion slot, and a tray for dispensed cash. There are also two lights.

## History

Switch

A railroad switch is a mechanical installation enabling trains to be guided from one track to another at a railway junction. A train moving from the narrow end of junction toward the switch blades will be directed to one of the two paths, depending on the position of the switch blades. A train coming from either of the converging directs will pass through the switch onto the narrow end, regardless of the position of the switch blades, as the vehicle's wheels will force the switch blades to rearrange if necessary.

A switch can be operated from a distance using the comms radio or manually while standing directly next to it.

A train driver can recognise the switch setting from a distance by looking at plates mounted on the switch stand or at a lever at the bottom and their arrangement in relation to the pole. It could also be determined using the comms radio - when in "switch mode" and pointed at a switch, the comms radio will display an arrow to the left or to the right, accordingly to the switch setting. Eventually, one can look at the switch blades and their arrangement.

Warning: do not change a switch under a passing train - it may cause a derailment.
Steel Mill

Steel Mill is the first station the player reaches once they complete the tutorial. It is a fairly simple yard with most of the early game necessities. Steel Mill imports Iron Ore from the Iron Mines, Coal from Coal Mine, and Argon from Harbor. It exports every type of Steel Product to Machine Factory and Goods Factory, Rails to Harbor, and empties to various other stations. The shunting jobs in Steel Mill can get a little complex with it's somewhat strange layout of the A tracks but it is a good starting location as there are no Hazmat materials exported and those the player may contact are usually only in shunting jobs.

Steel Mill has a Diesel and Steam Servicing shed with a repair station along with a turntable with 2 radial tracks off of it. Before Overhauled it had a shop as well.

Flashlight

The Flashlight is an item that provides a cone of light in front of the user. It can be toggled on and off to save power, as it's powered by batteries charged from solar power. It's current level of charge is indicated by the power bar with green, yellow, and red lights. It can be used underwater. It can be charged using the charger in the caboose. It was released as part of the Simulator update.
Wheel slip

A condition that occurs when the acceleration forces of the locomotive exceed the friction forces between the wheels and track. This only happens on driven axels and not cars being pulled.

## Cause

A locomotive (although heavy) has pretty low friction on the tracks because it's steel wheels on steel rails. This allows a considerable amount of weight being moved with comparatively little power, but it also can cause problems when not careful.

Regardless of how much weight is pulled, there is a maximum amount of traction forces that a locomotive can generate before the wheels start slipping. This amount does not change with the amount of weight you try to pull. The attached weight merely changes how quickly you accelerate with a given amount of engine power.

## Effect

Wheel slip drastically reduces the friction between wheels and tracks. This means you lose almost all power to pull the train. It also causes damage to the wheels, which you will then have to pay to repair.

## Indication

The diesel-electric locomotives have an indicator lamp for wheel slip. Wheel slip on the stream train can easily be heard because of the open cabin design. The locomotive remote also has a lamp and accoustic indicator.

## Resolution

Wheel slip can be resolved by either reducing the throttle, or by deploying sand. Sand increases wheel friction, but has to be refilled while generating maintenance cost.

## Prevention

The best way to prevent wheel slip is to operate the throttle gently. You will eventually gain the experience and learn how far you can set the throttle for a given speed. For example, at around 57 Km/h you can fully set the throttle on the shunter and not cause wheel slip. When standing still, you can set it to around 20-25%.

## Physics

Wheel slip happens when the acceleration forces exceed the friction forces between the wheels and the rails. The acceleration force gets bigger the further you set the throttle and gets smaller the faster your train goes. This is because of how induction motors work.

A second force you're fighting against is gravity when going uphill. This force gets stronger when your train gets longer and heavier. This can go to the point where it alone exceeds the friction force of the wheels, making it impossible to get further up. In this case you have to use multiple locomotives or try to make a run up and go fast enough to overcome the hill with the built up inertia of the train. When in immediate risk of stalling, deploying sand can help and may increase the wheel friction beyond the gravity forces again.

## Trivia

This force balance also limits how quickly a train can stop, but it can be overcome with the train brake because all cars have brakes, giving you access to the friction forces of all axels, not only the driven ones.

The independent brakes are sometimes not strong enough and you may find that a heavy train continues to accelerate downhill with only the independent brakes applied.
Locomotive remote

The locomotive remote is purchased in the shop at Machine Factory & Town. It is used to change the controls of a locomotive from outside the locomotive's cab.

The main advantage of the remote is that it can make shunting far easier, as the player will not have to be in the cab to operate the engines controls, allowing them to better see what is going on when at the other end of a train. This can also allow the operation of multiple locomotives at once to pull heavier trains, with the player in the cab of one locomotive while remotely controlling another using the remote. Its digital readouts can also make it easier to gauge a train's speed rather than having to read the in-cab speedometer.

Keep in mind that the locomotive remote only works on the DE2 and DH4, making it useless should you find yourself stuck with just an S282, DE6, DM3, or an S060 The remote is also battery-powered and fitted with a solar panel, and will drain its battery if not exposed to direct sunlight or connected to the caboose's charging unit. Finally, the locomotive remote has limited range (a maximum of 650 meters); should you take the remote past 400 meters, the remote will struggle to maintain a signal with its paired locomotive, and beyond 650 meters the remote will lose the signal completely. The remote's signal can be boosted if used near the caboose.

## History

* Remote charge speed no longer depends on sun direction

Build 88:

* Stylized “boosted signal” to “sgnl boost” for consistency

Build 85:

* Added signal boost light

Build 82:

Other places

The following locations are either unmarked or do not have stations of their own, and simply exist for some form of decoration or to store the game's crew vehicles.

**SPOILERS AHEAD FOR THE SECRET VEHICLES AND THEIR LOCATIONS!**

## Home

A small white house that effectively serves as the player's home. The house is located at the end of a spur track on the branch line leading to Forest Central. Aside from serving as a place to store items you don't need, the house currently doesn't hold anything of value, and only functions as decoration and as an additional Lost & Found location. Lost items will appear on the front porch.

The house is also the only non-station location that appears on the map, marked by a white house icon in a red circle. While it can be fast-traveled to, it will still cost money.

## Old Bob's garage

Old Bob's Garage is a shed located at the end of a spur track between Machine Factory & Town and Iron Ore Mine West. It can be unlocked by purchasing Old Bob's Garage key at Food Factory & Town for $5000. The key can then be used on the lock on the door of the garage. This will unlock the garage doors, allowing you to take the vehicle inside: the handcar.

## Reginald's garage

Reginald's Garage is a shed located at the end of a spur track between Forest South and the Sawmill. It can unlocked by purchasing Reginald's Garage key at City SW for $25,000. The key can then be used on the lock on the door of the garage. This will unlock the garage doors, allowing you to take the vehicle inside: the caboose.

## Steve's Garage

Steve's Garage is a shed located at the end of a spur track South of Harbor. It can be unlocked by purchasing Steve's Garage Key at Harbor for $20,000. The key can then be used on the lock on the door of the garage. This will unlock the garage doors, allowing you to take the vehicle inside: the slug.
Career manager

Career Manager and Job Validator

The career manager is used to pay fees, purchase licenses, and view information about both. They can be found in every Station Office, next to a job validator. They have a black exterior with a metallic "CAREER MANAGER" sign, a large screen, 5 buttons, a printer slot, and a payment slot. The five buttons from left to right are "up", "down", "cancel", "confirm", and a green "print info" button.

A career manager can also be found in the caboose. While there's no job validator to accompany it, it functions the same as its station-bound counterpart, allowing you to pay fees and service locomotives on the fly.

EOT Lantern

**The EOT Lantern** is a red lantern used to mark the end of a train (EOT). It is a weak, handheld omnidirectional red light source. The EOT lantern can be attached to an empty coupler by clicking on it while holding the EOT Lantern.

The EOT Lantern must be lit using the Lighter. The brightness can be adjusted by turning a piece of wire on the base of the lantern. You can buy 3 EOT Lanterns in total, and they are sold at the Machine Factory & Town Shop. It was added as part of the Simulator update.
Tank car

48,000 kg (Petrol)

The tank car is a car used to carry fluids. There are 6 variants of the tank car that function 3 different ways in the types of cargo they can carry. Chrome, white, and yellow tank cars carry oil, blue and orange tank cars carry gas, and black tank cars carry chemicals. All variants weigh 23,000 kg and are 14.52 meters long.
Passenger car

Passengers cars are used to carry passengers.

They are not used for Jobs currently, and can only be spawned in using the Comms radio's Spawner Mode. Red, blue, and green versions exist. No visual change occurs when the Comms radio is used to load one with passengers, but the weight does increase by 6,000kg. They have 68 seats. There is a bathroom and boarding doors at each end of the car.

## Bugs

In derail valley simulator, the passenger car's windows are broken, and have a distorted black effect.

## Gallery

Day and Night cycle

Derail Valley features a Day and Night cycle where time flows and the sun and moon rise and set. This affects the train handling environment and player's vision, as well as solar-powered equipment. By default, the cycle lasts two "real-life" hours, which translates to five "real-life" minutes for every in-game hour.

Time can be kept track of using clocks in the station offices, and the pocketwatch which can be purchased at a shop. If a player wants to pass time, beds are available for use.

When visibility is reduced, there are various sources of lights. In addition to lampposts, there are headlights, taillights, gauge backlights, and cablights on locomotives, and items such as the flashlight, lantern, comms radio, and the lighter.

Old Bob's garage

"Old Bob's Garage is a shed located between the Machine Factory & Town and the Iron Ore Mine West. It contains a secret vehicle..." - Handcar.

## Description

Old Bob's Garage is a shed, located at the end of a spur track, between Machine Factory & Town and Iron Ore Mine West. It can be unlocked by purchasing Old Bob's Garage Key at Food Factory & Town for $5,000. The key can then be used on the lock on the door of the garage. This will unlock the garage doors, allowing you to access the handcar. Unlocking the garage will also allow the handcar to be spawned using the Comms radio.
Reginald's garage

Reginald's Garage is a shed located between Forest South and the Sawmill. It contains a secret vehicle - Caboose.

## Description

Reginald's Garage is a shed located at the end of a spur track between Forest South and the Sawmill. It can be unlocked by purchasing Reginald's Garage key at City SW for $20,000. The key can then be used on the lock on the door of the garage. This will unlock the garage doors, allowing you to take the vehicle inside: the Caboose. Unlocking the garage will also add the caboose to the summonable crew vehicle list in the Comms Radio, though it will cost you $5,000 to summon it.
Lighter

Lighters can be purchased from shops for $150. Their main use is to ignite the firebox of steam locomotives by throwing one in, after which it will return to your inventory and can be used again. It can ignite flammable cargo leaking from damaged cars.

To use the lighter: 1. Hold the lighter in your hand. 2. Use mouse wheel scroll to open a lid. 3. Left mouse-click to lit the fire. 4. Throw the lighter into opened firebox (default G to throw item).

If the lighter does not fully enter the firebox, it can become "stuck" due to the firebox doors taking interaction priority. If this happens, lean into the firebox with Q or E and try selecting the lighter again.

As part of the simulator update, it will become a weak light source, and can be used to light the lantern.
Boxcar

29,000 kg (Chickens)

33,000 kg (Pigs)

32,000 kg (Sheep)

36,000 kg (Cows)

31,000 kg (Goats)

Boxcars are used to carry cargo such as livestock, prepared foods, and various other freight.

There are 6 variants of the boxcar, 2 of which have differing functionality. The normal boxcars for non-perishable and non-military goods are brown, green, pink, and red. The refrigerator car carries perishable goods. It has a white paint job and a mechanical refrigeration unit on the back of the car. The military boxcar is a special kind of boxcar that can carry ammunition, and is painted with a darker green camouflage pattern. The normal and military boxcars weigh 20,000kg, while the refrigerator car is 21,000kg. All of them are 14.12 meters long.
License

Licenses are the main career progression system in Derail Valley. Earning or purchasing a license unlocks new features such as new locomotives to drive, hauling more cargo of different types and more job types. There are 22 licenses in the game, three of which are earned after completing the tutorial. The other 19 are unlocked by purchasing them at a career manager while having no active fees. After unlocking most licenses, there will be an increase to your copay and a decrease in time to earn job bonuses. Licenses that are tiered require lower tiers to be purchased first. A table showing costs and benefits is below (Standard difficulty). Some jobs require more than one license simultaneously (e.g. Freight Haul + Train Length 2 + Hazmat 3). It is not necessary to carry any papers of the bought licenses in the player's inventory - they may be left anywhere and ultimately will show up in the Lost & Found. Player can check a list of bought licenses at a career manager at any time.

Turntable

The **Turntable** is a device for turning locomotives around. It can be rotated by pushing the handle on the turntable itself, or by pulling the lever in the nearby operator's shack in either direction. Not all stations have the Turntable although those that don't usually have circular tracks that allow you to turn the train simply by going around(the sole exception is the Farm which has neither)

**Always apply brakes on the locomotive before using the Turntable,** and if you have several locomotives apply brakes on all of them. The table can be rotated very quickly using the shack and without brakes you risk that the centrifugal force will slingshot your locomotives out of it.

A locomotive is considered to be on the turntable as long as all of its wheels are; it doesn't matter if parts of the chassis are sticking out. Some possible combinations include:

* 3x DE2 Shunter
* 2x DH4 Diesel Road-Switcher
* DE2 and DE6
* DE2 and DE6 Slug
Comms radio

The comms radio is an item used for 4-6 functions, depending on settings. It is the first item the game tells the player to pick up, during the tutorial. It has a display, that provide the player with informations regarding active function. A laser beam comes out of it to make it easier to point at objects. The beam color varies accordingly to the selected function.

"Switch" (red beam) is the default option. Pointing the radio at any switch and activating the radio will change the direction the switch is pointing. When hovering over a switch, a left or right arrow indicating the switch's orientation in relation to the player's perspective will appear on the bottom right of the screen.

"Rerail" (green beam) allows the player to place derailed cars back onto the rails, for a fee.

"Clear" (yellow beam) allows the player to delete a car from the world, for a fee (unless it was a spawned car, see below).

"Crew vehicle" (blue beam) allows the player to spawn a handcar or caboose, once they have been unlocked.

If "Comms radio spawn mode" is turn on in the "game" submenu of options, the "Spawner" and "Cargo loader" functions are unlocked for use. The train spawner allows spawning in any car onto an appropriate section of rail. The cargo loader allows you to load cargo onto these spawned cars.

The radio has a black and yellow color scheme and is branded with "Telelocotek".

		- Crew mode - Spawn a handcar if unlocked, at no cost
		- Spawn mode - Spawn any vehicle (replaces the old spawn tool, now also works in VR)
		- Cargo mode - Add cargo to spawned vehicles

* Improved switch remote mode aiming precision
Multi-Unit

Multi-Unit or 'Multiple unit' refers to coupling multiple locomotives together so that they operate as one, with controls automatically being mirrored across all units accordingly to the one the player is controlling.

## Requirements

To multi-unit, the player requires:

* The 'multiple unit' license
* At least two compatible locomotives
	+ And the license(s) to use them

### The license

The 'Multiple Unit' license, shortened as MU, requires the 'Concurrent Orders 1' license to have been bought, after which it can be purchased at any Career Manager for $30,000.-. Purchasing it will raise the copay amount by $5,000.00 and decrease the time bonus deadline by 1%.

### Compatible locomotives

Any locomotives with the Multi-Unit cable can be coupled up together, even if they are of different classes. The locomotives do not need to be facing the same way (i.e. 'cab forward'). Currently, the following locomotives possess a Multi-Unit cable:

* DE2
* DE6
* DH4

## Usage

Multi-Unit allows for an easily manageable enhancement of hauling capacities. This way, almost any train can be pulled even if the player only has the DE2 license as long as enough locomotives are linked together.

While it's possible to link different types of engines it is generally not recommend to link DH4 and DE2/DE6 because of large differences in throttle fidelity(DH4 throttle has 7 steps while DE2 has 11 and DE6 has 10; so changing throttle on one engine will disproportionally affect the throttle on the other) which usually results in one of the locos pulling most of the weight.

DE6 and DE2 is a popular combination as it can give DE6 the Locomotive remote functionally through the DE2 but again care needs to be taken when using the throttle as DE6's motor transition takes a while to actually provide power and during that short time the DE2 will be the sole working engine, often resulting in a wheel slip - the throttle needs to be changed only one step at a time. Alternatively, you can simply connect the DE2 but not turn on the engine at all as only the electrics breaker needs to be up to pair the remote. Yet another way is to connect the DE6 Diesel Slug to the DE2 which will all but eliminate the risk of wheelslip(and overheating)
Crew vehicle

Crew vehicles are cars that can be spawned with the comms radio. They must be unlocked by purchasing garage keys from shops and using said key to unlock garages containing the vehicles

## Handcar

### Type

Handcar

The Handcar is a generic, wood framed, handcart with a "foot pedal" brake. To use it, in non-VR, the player can use their throttle keys and alternate back and forth with the pumping motion of the cart's handles, use the mouse wheel in a similar fashion, or even click and drag it. To brake, the player pushes the brake down either using their mouse or their locomotive brake apply key.

In order to obtain the Handcar, one must purchase the Old Bob's Garage Key in Food Factory & Town, then locate Old Bob's garage and use the key on the door lock.

## Caboose

A caboose is a specialized wagon, providing additional braking power and housing brakemen, who would watch for slack-action in the train and apply the brakes in case of a breakaway.

## Caboose

### Mass

22000 kg

In-game, the Caboose is the only rail vehicle, besides the handcar, to have a functional handbrake. Other functionality includes storing items, an on-board Career manager, a Remote Controller charging station and boosting the Locomotive Remote's range by 2 kilometers. The Caboose itself is marked on the map by a red square. Clicking on said square allows the player to teleport inside, free of charge. Using the crew vehicle spawner mode on the Comms radio, it can be spawned for $10.000.

In order to obtain the Caboose, one must purchase the Reginald's Garage Key in City Southwest, then locate Reginald's Garage and use the key on the door lock.
Home

The "home" is a house located on the end of a spur track between the Forest Central and Farm.

## Description

The home is a small, one storey building with a living room, bedroom and toilet. It also has a porch which acts as Lost & Found. It can be fast-travelled to using the map.

Outside of retrieving lost items, the home currently has no purpose but the fact it's specifically marked on the map means it may have a purpose in the future.

Glitches and bugs

This page documents current glitches and bugs in Derail Valley, and how to fix them if possible.

* Speed limit signs being on or close to the right of way (tracks). They were created procedurally and will be fixed at some point in the future. They do not have collision boxes.
* Speed limit signs sometimes show incorrect values for their section of track, or are placed too close to one another.
* Cars spawning on top of each other. This only seems to happen now in corrupted saves from what some users have experienced, but is a known bug.
* Since build 81, and as of build 83, damage on the SH282 tender is disabled due to a bug that caused it to take excessive damage.
* The service station at Oil Well North can be hard for the DE6 and SH282 to access due to their size.
* Couplings sometimes become stuck on themselves.
* The SH282 tender sometimes becomes stuck on passeger station platforms.
* The connecting rods on the SH282 are rotated 180 degrees apart from one another, when they should be rotated 90 degrees apart.
* Several gaps in the terrain exist around the Valley.
* Northeast bridge to Food and factory and town has bad tracks that can derail cars.

You are Delsin Rowe a member of the Akomish however unlike the rest of them you are a conduit.

The game is an amazing open world game where you can choose to be a criminal or a hero.

The only bad thing about this game is that for one of the trophies you need to complete the game with ultimate difficulty.

Shovel

A shovel is a tool used for throwing coal from the steam locomotive's tender into the firebox, to produce heat and power the locomotive. Before operating the steamer, player have to buy it in any Shop.

Three versions of the shovel exist - regular, golden, and expert.

## Types

### Regular

The regular shovel is your plain old steel locomotive shovel, taking 2 shovel fulls in non-vr to fill the firebox. It can be purchased for $250 in any shop.

### Gold

The Gold Shovel is engraved with fancy carvings and takes only 1 shovel full to fill the firebox. It can be purchased for $20,000 in shop at Goods Factory

### Expert

The expert shovel is smaller and does not fill the firebox as much as the other two, allowing for finer control of how much coal is used. It takes 6 shovel fulls to fill the firebox. It can be purchased for $5,000 in shop at Goods Factory.

## History

Build 90:

* Added Expert Shovel
	+ Can be bought in a shop
	+ Adds less coal than default shovel (for precise firebox control)

Build 89:

* Revamped **shovel** interaction
	+ Allows twisting and using with both hands
	+ Entirely rewritten code (for dual-handed item interaction in general)
	+ Fixed visually adding coal on shovel from empty tender
	+ Decreased amount of shoveling needed to fill up the firebox
	+ Coal fling yet todo

## Industry Chain

### Produces

* Plywood, Wooden Boards
	+ Delivers to Goods Factory

## History

Build 84:

* Fixed the tight turn between B and C yards

Build 81:

* Loosened turns on the route north of Sawmill
Caboose

A caboose is a specialized wagon, providing additional braking power and housing brakemen, who would watch for slack-action in the train and apply the brakes in case of a breakaway.

## Caboose

### Mass

22000 kg

Other functionality includes storing items, an on-board Career manager, Remote Controller and Flashlight charging stations, and boosting the Remote Controller's range by 2 kilometers. The Caboose itself is marked on the map by a red square. Clicking on said square allows the player to teleport inside, free of charge. Using the crew vehicle spawner mode on the Comms radio, it can be spawned for $5,000.

In order to obtain the Caboose, one must purchase the Reginald's Garage Key in City Southwest, then locate Reginald's Garage and use the key on the door lock. This is also the only caboose in the game - unlocking Reginald's Garage will not cause additional cabooses to spawn.

Prior to the Simulator update, the Caboose was the only rail vehicle, besides the handcar, to have a functional handbrake.

## Trivia

The Caboose appears to be heavily based off the BNSF "Extended Vision" caboose design, or a similar design. However, the ingame version's body appears to be made of wood, similarly to older designs.

## History

Build 88:

* In case of reset tracks, Caboose will retain items left in it
* In case of reset tracks, Caboose will teleport with the player to the nearest station
	+ Will happen if the Caboose was attached to the train you were last using
	+ Will happen if the Caboose was within 1.5km of the player in the last session
	+ Will happen in #87 -> #88 build transition
* Added charging sound to Caboose loco remote charger

* Added colliders to buffers
* Added keyboard control to independent brake

	+ Features a fast battery charger for the Loco Remote
	+ Visible on map (useful as end-of-train marker)
	+ Contains its own Career Manager (allowing mobile or remote area servicing)
	+ Allows free teleporting between it and the locos in the same train (“jump”)
	+ Can be summoned using Comms Radio for $10k
	+ Has its own independent brake
	+ Has stronger brakes than other cars/locos
	+ Can be used to store items
	+ Doesn’t take damage (until locomotive ownership is added)

Lantern

The Lantern is an item that creates a mild amount of light in all directions. The lighter is required to light it, and it's intensity can be adjusted using the wick dipping. Once lit, it is a permanent light source. It is planned for addition as part of the simulator update.

There is also a red lantern variant planned which can be attached to coupler for use in end of train signaling. Could be part of simulator, but uncertain. - /u/altfuture Wednesday, January 25, 2023
Lost & Found

The Lost & Found shed is where the player can find any lost items. It is located next to a Station Office and dumpster at a station. It is made of unpainted wood and has a metal roof. Inside is a table that any lost items will spawn on. Content of the shed is exactly the same at all stations. It means that any item that will be put there on one station will be also available in all sheds at any other station.
There also exists a button to return all purchased items which are not in the player inventory to the shed. This may be necessary if an item is placed in an interactive area and cannot be retrieved normally, such as a lantern on a bed.
Damage

In Derail Valley, the locomotives, cars, and environment can be hurt in various ways due to impacts, derailments, and operation errors.

Updates to the damage system are planned for build 93.

"On DE and E loco types, overheating the TMs can result in either receiving minor damage and shutting down the breaker, or dying entirely (causing bigger damage), or catching on fire (causing big damage and some more over time until the fire goes out). This can happen when taking too big a load, accelerating too harshly, going up a very steep grade, switching to reverse while going forward, etc.

On DH and DM locos, the transmission (fluid coupling) can overheat and blow up. This results in major damage to the powertrain and renders the loco immobile until repaired. Like with DE/E types this can happen from too big a load, or mishandling the gearbox.

On S locos, exposing the crown sheet to boiler can result in the boiler exploding. Also having water in cylinders can crack them (either due to priming (overfilling), or due to water condensation forming in the cylinders). The latter isn't super expensive to repair, but it will render the loco immobile.

Diesel fueled locos can explode if their body health reaches 0% due to fire damage and their tanks aren't empty. Exploded locos have all of their health categories put to 0% and a different appearance inside and outside; it does cost a lot to repair them. All the loco types can get major damage if not supplied with oil.

Brake pads can also overheat if misused, which can lead to being unable to stop the train.
