In GTA: Liberty City Stories, it is revealed in "Bringing the House Down" that a disused portion of subway exists underneath Rockford and Fort Staunton in Staunton Island. The system, cut off from the rest of the active subway system, consists of two lines, two antiqued subway stations, and two old subway train wrecks (one at the first station and the other at the last station).
Events of GTA Liberty City Stories
During the mission "Bringing the House Down", Donald Love phones 8-Ball and informs Toni Cipriani that the weakest points under Fort Staunton is the new Porter Tunnel development and this abandoned train station. Toni drives a van full of explosives to Fort Staunton.
He then enters the Porter Tunnel and drives to various parts of the Tunnel and subway tunnels, planting the explosives. Toni then leaves the tunnels, killing any construction workers who are witnesses. He escapes in a vehicle, just as the explosives detonate, destroying the entire Fort Staunton neighborhood.
After the events of GTA Liberty City Stories
The Panlantic Construction Company eventually moved in to redevelop Fort Staunton, clearing away nearly all remnants of the neighborhood to start the construction of Staunton Plaza. There is still a short tunnel under the area in Grand Theft Auto III that may be the only remaining bit of the disused subway tunnel Toni Cipriani used to plant the explosives, alongside several shells of buildings.
