It's all getting connected and high-tech now. I once made a mistake of forgetting to change the tail lights from Marker lights only to Auto, (train had been berthed the previous night at buffers with white lights). Get to destination, change ends then pull leave. Alarm flashed up after pulling out and thought oh bugger! First stop was only about 1 minute away, yet before I had pulled in I had a "contact signaller" message on GSM-R. "Hello driver, control just wanted me to tell you your marker lights are still on in rear of your unit"
Big Brother is always watching, of course our units send faults to maintenance desk who sit next to control!
