Bug: If you are driving the steam train, it is impossible to let the fire burn out completely (even if you let the 'Fire Mass' gauge on the HUD go completely to 0) as smoke still emits from the smoke stack.
Bug: This is most prominent on the Tokyo line but applies to all the electrical routes in this game. On most of the branch lines/sidings, the overhead wires stretch for miles with no support gantries whatsoever and if you pull into a siding, the wire just magically ends floating in mid-air.
Bug: The enclosed stations (i.e on the far end of the North East Corridor line), must have very leaky roofs because if it is raining when you enter the station, the rain is still seen through the train's cab.
Audio problem: On the steam trains, when you start shovelling coal into the firebox, the sound of the coal rattling is heard. However when you turn the shovelling off and shut the firebox doors, the shovelling sound carries on.
