Class 442 5-WES 2416 passes Potbridge on 28 April 1991 with the 08:24 Poole to Waterloo Network SouthEast service. One of these stylish units holds the world speed record for a third rail EMU of 108 mph. The limiting factor of course not being the traction equipment or the third rail itself, but the shock of the pickup shoes hitting the start of each rail section.
