British Rail Class 323 - Definition and Overview

The British Rail Class 323 electrical multiple units were built by Hunslet TPL from 1992-93. 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.

Description

In the early 1990s the Regional Railways sector of British Rail placed an order for new EMUs to both replace older units and to work services on the newly electrified Birmingham Cross-City line. The contract was awarded to Hunslet TPL in Leeds, who at the time were in financial difficulties due to lack of orders. It was hoped that the builder of the Class 323 units would turn the fortunes of the company around. However, this was not to be the case, and these units proved to be the last trains built by the company. The trains were also some of the last constructed before the infamous 1,064 day gap in train orders.

Forty-three 3-car units were built, numbered in the range 323201-243. Each unit is formed of two outer driving motor vehicles, and a central intermediate trailer with a pantograph for collecting the overhead current of 25kV ac. The technical description of the unit formation is DMSO+PTSO+DMSO. Individual vehicles are numbered as follows:

• 64001-64043 - DMSO
• 72201-72239 and 72340-72343 - PTSO
• 65001-65043 - DMSO

In general, the last two digits of the vehicle number correspond to the last two digits of the set number, such that unit 323227 is formed of 64027+72227+65027. The last four PTSO vehicles are numbered in a separate range to avoid clashing with Class 365 vehicles.

Current Operations

Central Trains

Central Trains inherited a fleet of 26 units, comprised of sets 323201-222 and 323240-243. The units were delivered in 1993/94 painted in Centro green and white livery with a blue stripe. They were originally allocated to Bletchley Depot, but have since been reallocated to a new depot built in Soho.

It was intended for the units to be introduced on the newly electrified Birmingham Cross-City Line from Redditch to Lichfield (via Birmingham New Street). However, all did not go according to plan, and initially the units suffered from reliability problems. This meant that the ageing fleets of Class 115, 116, 117, 118 and 119 diesel multiple units, which the Class 323 units were meant to replace, continued in service longer than planned. They were finally withdrawn in 1995 once the Class 323 units had become more reliable.

The units were also used on various other routes, including Coventry to Wolverhampton, and Birmingham to Walsall (Chase Line) suburban services, as well as longer distance Birmingham to Liverpool Lime Street services. On these services, they were used alongside the existing fleets of Class 310/1 and Class 312 slam-door units. The introduction of the new trains also allowed the withdrawal of the elderly Class 304 units, and the cascading of Class 308 units to operate suburban services around Leeds.

Since being introduced, the units have recently undergone works attention, which included the fitting of CCTV suveilance equipment. The Centro livery has also been modified, with the addition of yellow doors to aid the visually impaired.

First North Western / Northern Rail

First North Western inherited a fleet of 17 units.
