The game should provide paths to connect metro platforms and street entrances

[Ultra-realistic player]

Currently, metro passengers exit the platform via the "portals". This is very unrealistic.

For realism, I hope the game can remove those "portals" entirely. It should allow players to create special pathways (and it can be placed underground/elevated) to connect metro platforms and street entrances. This is the logic for all real life metro systems.

I hope the game can improve its realism by proceeding this update. The price of a metro system should be high enough to balance with other transport modes.
