British Rail Class 323
British electric multiple unit passenger train
The British Rail Class 323 electric multiple units were built by Hunslet TPL from 1992-96. Forty-three 3-car units were built for inner-suburban services around Birmingham and Manchester. These trains were the last vehicles to be built by the struggling manufacturer Hunslet before it collapsed.

Notes
change- ↑ Hunslet Transportation Projects Limited (HTPL) sold its Birmingham-based design, engineering, and project management functions – including responsibility for the Class 157 and 323 contracts – to the Dutch electrical engineering firm Holec in March 1994.[1][2]
- ↑ Between Birmingham and Bromsgrove.[11]
- ↑ The Alstom IGBT system delivers improved reliability, though – in order to avoid the need for expensive recertification – it is configured to emulate as exactly as possible the control and electromagnetic interference characteristics of the original system.[13]
- ↑ Both types of bogie are derived from the British Rail Engineering Limited (BREL) BT13 design.[15] RFS Industries was formed in 1987 through a buy-out by former BREL managers of British Rail's Doncaster Wagon Works.[16]
- ↑ The regenerative system is the primary brake for the train in normal operation, blended with the friction brakes as required. Emergency braking uses the friction brakes alone, at a force 30% above the normal 'full service' application.[17]
