Same here SoldadoARG, Posted about it in the EA Forums as well: Train Station Issue | EA Forums - 12082655. Having this issue happen to me on my PC playing Sim City: Build It through Bluestacks. Initially had the issue in my second city, but was able to get it up and running again after placing my Train Stations in Cloud Storage and placing them on the map again. Problem is you have to wait for the Passengers to stack up again. Starting to wonder if the New Train EA is implementing to the game in an upcoming update is part of the cause?
