Again, I don't remember if it was the FL9AC's or DE/DM30's at LIRR where, years ago, it was common for them to have to reboot the computers to get things working. The DM's have long had problems from time to time getting the 3rd rail system working. They would sometimes switch over before Jamaica in bound, and the train would stop, ventilation go dead, maybe the lights, and then they'd give up, try to restart the diesels to go into Jamaica to dump the trainload. Sometimes, they'd tell people to get off, then get it working, and go on into Penn with about 2 passengers per car. And sometimes the problem would be the opposite - they'd come out of the tunnels heading east, and try to start the diesels. If you were in the first car, you could hear and feel them trying, and you were praying for the huge cloud of black smoke, the rumble, and electrical power being restored. And at times, only one of the 2 DM's would work.
Sort of entertaining. But, IOTW, unreliable loco systems that are too complex are nothing new.
