This is ScratchFord Metro's Circle line. It runs in a loop and the depot is located at Albert Street Station. These trains are quite weird. These are OTIS Horizontal Elevators, based off of the transfer train at Zürich Airport. The announcements are quite weird. There is a different chime for each thing, LOL. Anyways enjoy the ride. BTW this train is somewhat slow...
Thanks to halfai93294 for the original project New Diamond City Metro - LINE 1.
