When the train arrives to the platform, take the very last door of the train. This glitch can be performed at the subway in Shoreside Vale at the airport. They can then walk along the tunnel, then jump into Blue Hell at the Shoreside Vale end, so that they can get teleported above the surface. The player then exits the vehicle, falling into Blue Hell, landing above the tunnel. The player has to reverse the car half off the wall above the middle of the tunnel. To do this one must drive a Bobcat to the concrete sea wall above the tunnel entrance. One is method of reaching Shoreside Vale early on in the game is by exploiting a glitch that allows you to walk above the Porter Tunnel.
