Expanded_Atlantic_Express_System  : my mapping of the larger system that Rapture would need to have .
Improved design used to replace much of the original Atlantic_Express Train system (which had been built rapidly to facilitate Rapture's Construction).
Structural Corrections/Improvements (over AE Mk1) :
* More Robust structure ( correcting deficiencies in original concrete track design )
* Major repairs/replacement of track largely worn out by City Construction
Improvements :
* Additional Capacity - for passenger and freight (larger cars)
* Greater Speeds and Eliminating Operational Delays
* Less Maintenance ( cheaper, fewer failures and lower costs )

Rebuilding and realignments - City expansion added newly important destinations and adjusted routes ( tunneled thru some ridges instead of going over/around ).
Passenger service was discontinued after the bankruptcy. TheMetro Transit Trolleys and Bathyspheres had taken much of the business which had been subsidized by the Freight operations ( much like what happened in the US in that same period ).
The AE System afterwards continued as a Freight operation ( the profitable part of the system )

An AE Traincar Issue :
AE Traincars - No need for those external Cockpit doors - a waste of design effort (over complication) if it was to be real. Rapture sea doors need to be substantial (because of the water pressure) and its another potential "point of failure" ( seal system, etc ... ). Entry should be through the main cabin ( still with that cockpit/cabin separation door, as already seen ). The cockpit itself is rather over-sized, and WOULD be smaller ( and there's no seat in it, which also would be an improvement needing fixing ).
They didn't want to have to show you/have you traverse the main cabin - the clunky game movement meant wide aisles, and to fit proper seats it would force the whole vehicle to be wider than it is portrayed ( My Mk1/Mk2 designs ( diagrams ) IS made a bit wider to make this more realistic ).

Double Cars :
The Larger Mk2 stations ( as seen on the Expanded Dionysus Park map ) can handle double Traincars, which as they are configured back to back allow normal movement in either direction - A definite advantage when many routes of the revised Atlantic Express system were single tracked. At the end-of-line locations, no complicated turning mechanism was thus needed for the Traincar's return trip. The MK2 cars were also substantially larger and could carry much larger passenger ( and later freight ) loads in the busy City. A single operator could also then operate 2 cars which was an important monetary 'labor' savings, over the older system.
