If the onboard system is working it does tell you it runs non stop, of course it never works and I've had it tell me numerous times the train is running non stop when its not
I know IE will roll out all class of excuses of software problems but it really depends on the driver more than anything else, they frequently forget to push the start button
I watched a stand off a few years back between a passenger and a driver when the system was way out of sync, driver kept saying he couldn't switch it off, 30 seconds later it shut down
