Based on the New York City Subway, the Subway in Liberty City in Grand Theft Auto IV, signed as LTA Rail, is a heavy rail rapid transit system that serves a large portion of the city. With 26 stops and 8 routes, it is the largest and most complex rapid transit system in the Grand Theft Auto Universe. The system is operated by the Liberty Transport Authority (LTA). The subway also appears in Grand Theft Auto: Chinatown Wars; it is inaccessible to the player, yet trains still run. About 65% of the network is underground, with the remaining 35% being overground. No platforms on the entire system are staggered and there are also no ground level stations or tracks in the entire system, except for the depot.
All stations in Broker, Dukes, and Bohan are located above ground; stations in Algonquin, aside from Frankfort High LTA, are underground, their entrances distinguishable by their green iron fencing and attached globe lamps. All stations in the system are operational except one, referred to as Dukes Boulevard station (by an LTA Construction Sign on the Station entrance) along a short stub branch of the Broker Line in East Island City; the line is also connected to the Firefly Projects Rail Yard. The cost of using the subway is deducted after the trip (with fares increasing based on the length of the ride, unlike the MTA's single base fare), as the ticket machines and turnstiles are not operable. Subway lines can be seen on the Radar in the HUD as semitransparent gray lines, with stations marked as square lozenges. If a station is underground, multiple access points will be available front street level, typically depicted in the form of a stairway leading underground surrounded by cast iron grills with lampposts attached in the corners. Some of the city's homeless can be found taking shelter in a the large junction tunnel under Lancet. Sometimes, the homeless will "commit suicide" and wander on the tracks, only to be hit by an oncoming train. These incidents can also happen at stations if a homeless person is on the platform. Normally this happens at Emerald subway station.
The subway is a good way to escape from the police at any wanted levels. At lower levels, players may still use the train; as the AI is confused by the player entering the trains, the train may take you well outside the wanted zone. However, use of the subway trains is impossible when the player has a three-star wanted level or more, as the trains will either stop at stations indefinitely, bypass any station the player is in, or are halted. Alternatively, the subway tunnels themselves may be effectively used by the player to escape on foot as police officers do not venture into the tunnels unless they spot the player earlier and pursue him into the tunnels. There is also a bug where the player may receive a 1 star wanted level when entering trains that are about to leave while police are nearby.
Subway trains are not operational, or even available, on multiplayer. However, access to the tracks is still available, and is a useful way to escape the police. Trains also run on a 'rail', i.e. they cannot move from their set route, and will not stop for any reason whatsoever unless coded to, even when their path is blocked (e.g. by a vehicle). The coded coordinates of the tracks can be altered with specific programs, by editing the path files.
Like their real life counterparts, the stations feature turnstiles and do not accept cash or coinage. Instead of MetroCards or tokens, the system uses paper tickets sold from ticket machines. The ticket machines resemble their real life counterpart MetroCard vending machines. The turnstiles, meanwhile, strongly resemble the High Entrance Turnstiles of the MTA, but instead of a rotating arm they use a push bar more commonly found in libraries. The stations also have metal service entry gates (usually open), though only one station is wheelchair accessible. Token booths are absent, replaced by the ticket machines and an unusually large police presence.
While the real-life subway is powered by electricity, third rail power delivery is only present at the Francis International Airport station and in the Firefly Projects Rail Yard. This may imply that the trains are diesel, or it could just be an oversight by the developers. A sign at Francis International Airport station contains the warning "Avoid third rail track, or you'll get zapped", indicating that at least some trains run on electricity. However, stepping on the third rail won't electrify the player.
The underground stations feature tiled walls and platform pillars, similar to the style of the BMT and IRT divisions of the NYC subway. Instead of mosaic-tile name tablets, stations are identified with dark blue signs with white text of the station name (in a different font than MTA styling). While the tunnels between stations have very low clearance, the stations have very high ceilings (with the mezzanines visible from platform level).
The entrance stairs bear strong resemblance to their real life counterparts, including the dark green metal design and distinctive globe entrance lamps.
The elevated lines are very similar to their real life counterparts, except that they are noticeably wide. Each line has two tracks, but have a third middle trackway unoccupied, while the structures are wide enough to fit at least two additional tracks (for an express service). Most stations resemble typical elevated stations, except for Lynch Street (which is based of the Forest Hills Long Island Rail Road Station) and Francis International Airport (based on the stations of the JFK AirTrain).
Like Grand Theft Auto III and Grand Theft Auto: San Andreas, it is impossible to destroy trains during gameplay. Trains are scripted to be decoupled in the mission For the Man Who Has Everything, derailed in No Way on the Subway, and destroyed in Bang Bang. There are no visible drivers on the trains, and trains cannot be commandeered by the player unless with a modification.
It is possible that there were actual train conductors controlling the trains in the early beta of the game, theoretically allowing them to be stolen and operated by the player and disproving the fact that trains would run in a scripted method.
In the game files, there is model named M_M_TRAIN_01, which is accessible and controllable by certain trainers. The model even has variations for clothes and accessories (hats and glasses).
There are also recordings for the unused model. There are exactly 113 files. "Walkie Talkie" recorded files also exist. During one of these recordings, he says that he saw "a rat the size of a pitbull in the tunnels". The train conductor model also seems to have a slightly similar appearance to overweight LCPD officers.
Abandoned Railway Lines
It is possible that the Liberty City Subway may have shared the tracks with (now defunct) freight trains in the past, as well as having a completely different route (possibly reserved for the freight trains).
There is an abandoned portion of an old railway in western Algonquin along Westminster and The Meat Quarter, It runs from the plaza of a new building (blocked off by construction barricades) through several buildings before splitting up. One section runs into a garage in a building (supporting the fact that it may have been used for freight), and the other leads to a broken off edge forming a ramp. This stretch references the real-life High Line freight railway in New York City, which ran in the corresponding areas of Manhattan (Meat District, Greenwich Village, Chelsea, and Hell's Kitchen) from the 30s to the 80s and in real life has become a park.
Several disused tracks and railcars also dot industrial areas in Alderney. These include two abandoned rail depots (one that has been almost completely torn down), several sections of track (mostly running through old alleyways), a section of track running by the old Sprunk Factory that splits up, with one side leading into a bricked up tunnel. There is also a rail line running from a bricked up tunnel running from southern Alderney City through Normandy and Port Tudor, finally ending on an incline with several old pillars present on the other end (suggesting a bridge or elevated line) near northern Acter Industrial Park. A section of this track also runs onto one of the piers in Port Tudor. This track is mostly intact, though several newer structures (roads, buildings) have been built over it.
In western East Island City exists a section of railway that leads from a bricked up tunnel west toward Algonquin, and stops facing that water, suggesting a bridge (possibly a Hell Gate Bridge replica, since it heads towards to Charge Island and is part of the subway) or waterside ferry/train transfer terminal may have at one point existed.
There also are two unused subway tunnels in the network, which form connections between two other lines, but are not part of regular subway routes: there is a tunnel which connects North Park Station to West Park Station and one which connects West Park Station to Frankfort High Station. Also, within the junction tunnel under Lancet, there are tracks which connect Easton Station to Manganese East Station. These tunnels would technically be used for alternative routes or for maintenance work, though there is no such in-game activity.
The subway system has four main lines, in pairs:
- The Algonquin Inner Line (Routes K & C) + Bohan Line (Routes E & B)
- The Algonquin Outer Line (Routes A & J) + Broker Line (Routes 8 & 3)
These four lines serve all boroughs of Liberty City, but do not serve the state of Alderney.
- Route A trains run clockwise
- Route J trains run counter-clockwise
- At Easton, Route J trains become Route 3 for the Broker Line
- At Manganese East, Route A trains become Route 8 for the Broker Line
- Route 8 trains run clockwise in Broker, counter-clockwise in Dukes
- Route 3 trains run counter-clockwise in Broker, clockwise in Dukes
- At Easton, Route 8 trains become Route A for the Algonquin Outer Line
- At Manganese East, Route 3 trains become Route J for the Algonquin Outer Line
- Route K trains run clockwise
- Route C trains run counter-clockwise
- At Frankfort Low, Route K trains become Route E for the Bohan Line
- At Frankfort High, Route C trains become Route B for the Bohan Line
- Route E trains run clockwise
- Route B trains run counter-clockwise
- At Frankfort High, Route E trains become Route K for the Algonquin Inner Line
- At Frankfort Low, Route B trains become Route C for the Algonquin Inner line
On every train, the intercom voice is a pleasant woman:
"This is the J train. The Next Stop is: Manganese West Station - Leaving Quartz West."
Although, if the player attracts a 3 star Wanted Level and the vehicle is stopped by the police, a man will say:
"This train terminates here, all change."
This is an example of an approach announcement, spoken by the woman:
"The Train is approaching Castle Gardens station." (This will sound about 7-8 seconds before the train actually reaches the station)
- There is a glitch in one of the underground entrances. If you drive into the fencing of the entrance around the back of them with the front of your car, head on, get out and then get in the passenger seat and reverse. As soon as you get back into the drivers seat, you should turn invisible in your car.
- Subway trains are scripted to be decoupled in For the Man Who Has Everything, derailed in No Way on the Subway and destroyed in Bang Bang, but it's impossible to do these actions in normal gameplay.
- The Subway train has a unique horn, but can only be heard on the missions above.
- The player cannot board a Subway train if he has a 2-star wanted level.
