Very interesting. Can you do UK Hitachi trains? They are notoriously unreliable on the software side. E.g. pressing the emergency button in a toilet can basically disable a train. I experienced that once myself, when a small child pressed such a button while the train was at a station, and after 40 minutes of frantic activity, even involving engineers called from a depot nearby, we were told to disembark and board another train.

Maybe it's symptoms of the same disease, Hitachi wanting more maintenance contracts?
