Two-Platform Metro (No Mods!) :: Parallel

The default Metro Station with an additional platform parallel to the main one. The second platform is at -12m from the surface. See also the cross version.

This asset should work without any mods, so it does not compromise your achievements.

However, multi-track stations are very finicky and sometimes refuse to accept metro lines on particular tracks. I find that running lines through all tracks without stops first (i.e. putting a stop at the next station) helps in fixing this. Sometimes the order of tracks you place stops on is also important, especially if the same line visits the station more than once. Try putting one stop at the first platform, then another at the second one.
