Class & Prototype

  • Running Number: 79727

The British Rail Class 171 "Turbostar" represents Bombardier's specialised diesel multiple unit variant built exclusively for Southern Railway in 2003-2004. These units are mechanically identical to Class 170 siblings except for Dellner anti-climber couplers enabling emergency coupling with Class 377 Electrostars. Powered by MTU 6R 183 TD13H diesel engines producing 315 kW per vehicle through Voith hydrodynamic transmission, the fleet operates the Uckfield Line (London Bridge to Uckfield) and Marshlink Line (Eastbourne to Ashford International) serving rural Sussex and Kent routes beyond third-rail electrification. The current fleet comprises approximately 4 two-car and 12-13 three-car units following 2022 reformation.
