This is one of my oldest cities, and also one of my first attempts at creating a cross-platform interchange in the game.

I reversed the driving direction of the Green Line — from the right to the left — so it could form a cross-platform interchange with the Pink Line, in order to make river crossing easier. In the tunnel section (not shown in the video), I switched it back to a regular same-direction parallel interchange. I’ll share my track configuration diagram and more screenshots of the full metro system (yeah even custom made train and metro cross-platform interchanges) if anyone’s interested.
