Great Northern 717017 (Siemens Desiro City) for trains from London Moorgate station, equipped for 750 V DC side rail and 25000 V AC overhead wires. The line uses the Moorgate tunnels which don't provide a walkway next to the train, so in emergency the train must be evacuated through the front door onto the track.
