This is a modern suburban train station, with one platform and two tracks. Passengers boarding trains on the outer track wait on the main platform, and after their train arrives they cross the near track to the yellow boarding platform. Of course, this means no trains can pass through the inner track while this is happening! This is modeled after the way many stations on the Caltrain line are designed (but for safety and scheduling reasons, they are moving to a two-platform design on many of the stations).
The feature which started this model is the tile mosaic floor in the waiting area. I got the idea while riding Caltrain. When we were stopped at the Redwood City station I noticed the pattern in the concrete waiting platform of a grid of squares surrounded by long strips. Theirs wasn’t multicolored, but then theirs wasn’t built from LEGO either. :-) The station building was not based on anything from real life, though. I tried to use an archetypal station design. Note also the ticket vending machines on the station wall – tickets must be purchased before boarding!
