The British Rail Class 323 is a class of electric multiple unit (EMU) passenger train built by Hunslet Transportation Projects and Holec. All 43 units were built from 1992 through to 1995,[5] although mockups and prototypes were built and tested in 1990 and 1991.[22]
Entering service in 1994, the 323s were among the last trains to enter service with British Rail before its privatisation in the mid-1990s. The units were designed to operate on inner-suburban commuter lines in and around Birmingham and Manchester with swift acceleration and high reliability. Of the 43 units built, 34 are in service with Northern Trains, with the remaining 9 being in storage.
The units are known for their rapid acceleration, being the fastest-accelerating trains on the UK rail network.[citation needed][dubious – discuss]
