A Class 313 emu with North London Line

Photograph taken on: 29 June 2003. (Larger image)

One of Class 313 emu fleet dwelling at North Woolwich station, when I took the North London Line service to see Woolwich Free Ferry. The train is equipped with the dual-voltage system (25kV 50Hz overhead / 750V dc third rail). On North London Line both voltages are required; however, the switchover from one supply voltage to the other is not noticeable as a passenger on board. The drive mechanism is, as usual for British railcars, nose suspension drive.
