Actually Shoota want the ****ing answer smartass? They WERE In the Matrix, the corridors are in a different PART of the Matrix - hence the reason Link had to find them everytime they entered it.
Mobil Ave is something TOTALLY different than the corridors. The corridors are back-doors for The Matrix. The Trainstation was built by the Trainman to transport people FROM the Matrix TO the Machine World or Vice-Versa.
So before opening you smart-ass mouth, use the muscle that matters.
