Good day
I was running around in the EU07 on the EN1 server (can't remember the station), and I got routed onto a track without overhead catenary. Instinctively I put down my pantograph, and coasted towards the exit signal. After I stopped, I put the pantograph back up, just to see what would happen. To my surprise, when it got up, i managed to get power, even without the overhead electric wire. I assume this is a bug.
