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.
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.
