Class 323, no. 323209 waiting at Birmingham New Street on 24th September 2003. This unit was operated by Central Trains (now London Midland) and is painted in Centro livery.

The British Rail Class 323 electric 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.

[edit] 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 Transportation Projects Limited of Birmingham, who were a new company set up by a team of engineers and managers that had left Metro Cammell. Metro Cammel were also at the time a Birmingham based renowned train builder. During the course of the project the company was acquired by Jenbacher transport system who supported the company in the hope of further orders for new trains but these units proved to be the last trains built by the company for the UK market. The trains were also some of the last constructed in the UK pre rail privatisation as Class 323 was in production just before the infamous 1,064 day gap in train orders. Hunslet TPL went on to deliver designs for Keretapi Tanah Melayu Berhad Class [1] 81 EMU which was built under the company's control and Glasgow Underground Trailers which were assembled by sister company Hunslet Barclay. Presently the company continues in Birmingham as Transys Projects Limited they remain active in the rail industry providing consultancy, refurbishment and enhancements to rail vehicles both in the UK and internationally. See [2]

In December 2007 the Class 323 Units operated by Northern received a coveted industry award the Modern Railways "Silver Spanner" because a team engineers maintaining Northern Rail's 17 Class 323 trains had increased the service's reliability by over 100%.

Forty-three 3-car units were built, numbered in the range 323201-243. Each unit is formed of two outer driving motor vehicles (each equipped with four Holec DMKT 52/24 asynchronous traction motors), and a central intermediate trailer with a Brecknell Willis High Speed 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.

[edit] Current operations

[edit] London Midland

The former Central Trains inherited a fleet of 26 units from British Rail, comprised of sets 323201-222 and 323240-243. In November 2007, these were passed on to London Midland.

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 Soho when the elderly class 304's retired. Since the 323's moved there, a workshop has been built for maintenance and repairs.

It was intended for the units to be introduced on the newly electrified 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 surveillance equipment. The Centro livery has also been modified, with the addition of yellow doors to aid the visually impaired.

During 2008 the London Midland fleet received London Midland livery. During this refurbishment the seats have been retrimmed with the new London Midland trim, new labels have been applied inside the carriages and handrails on the seats are now yellow.

323205 has been fitted with a new experimental, prototype interior saloon lighting diffuser, called 'BASIL' (short for Bright Ambient Sensing Interior Lighting) which is slimmer, more modern looking and makes the interior look brighter. The lights are actually LED and automatically light up brighter whenever the train is in a tunnel or at night. The system does this quicker than the human eye can blink, so passengers cannot notice the sudden change in brightness.

New livery on a Northern Rail unit.

Northern Rail operated 323225 at Manchester Piccadilly station. This unit is painted in obsolete First North Western livery.

At the time of the privatisation of British Rail in 1997 North Western Trains (NWT) inherited 17 of these units, North Western Trains became First North Western and its operations were taken over by Northern Rail in 2004.

They were used to replace older stock of Classes 304 and 305, although some of the latter were retained in reserve until 2000. The units are used on services on the Manchester electrified network, which is primarily to the south of the city. Services include:

The fleet is maintained on behalf of Northern Rail by West Coast Traincare Limited at its Manchester Traincare Centre Longsight, which is a few miles south of Manchester Piccadilly with units stabled at Stockport Edgeley carriage sidings where they receive overnight cleaning.

The trains were originally painted in the Greater Manchester PTE livery. Two units, Nos. 323224 and 323233 were painted into NWT dark blue livery with gold stars. The franchise was later acquired by First Group and renamed First North Western (FNW). In the period 2003-2004, the entire fleet was refurbished, which included a repaint into FNW blue and magenta "Barbie" livery.

In December 2004, the Arriva Trains Northern and First North Western franchises were combined into a new Northern Rail franchise. Northern Rail is operated by Serco-Ned Railways (A joint partnership between UK company Serco Group and Ned Railways). The Class 323 units retained FNW blue livery, awaiting Northern Rail to finalise their corporate image.

In June 2007, the Northern Class 323s began a refurbishment programme that included the introduction of over 20 reliability improvement modifications, replacement of cab desk panels and new LED lighting for the front of the trains. No. 323239 was the first unit to receive this upgrade and was released back into passenger traffic on 18 August 2007.

On 6 January 2008, No. 323223 was repainted in Northern livery - the first Class 323 in the Northern fleet to be branded. This unit returned into service on 15 February 2008 in full livery.^[2]. 323225 has now received Northern branding, alongside 323230.

As part of the Department For Transport Rolling Stock Plan, published in January 2008, Northern's fleet of Class 323 EMU trains will be transferred to London Midland to create a uniform fleet and allow multiple EMU operation and 24 new units will be ordered for Northern.^[3].

323235 spent 6 months out of action after derailing at Alderley Edge. This occurred on 13 September 2008 when shortly after operating the 23:31 Deansgate to Alderley Edge service 323235 had run ECS into the up siding and was returning to Stockport for overnight stabling. It was at this point that the driver passed a signal at danger which resulted in the train derailed on the points, causing wheel damage to one of the bogies and damaging the traction motor. The unit was traveling at about 10mph when the incident occurred. During the time it was out of service receiving repairs, it was also put through the fleet modification program and was repainted in Northern Rail livery. It re-entered service on Saturday 24 January.

323231 is currently out of service after derailing at Congleton on December 18 after hitting a car which had rolled down Mow Cop. It is expected to be out for 12-14 months, with a return date of February 2010. It suffered lots of underbody damage as well as losing its pantograph. Due to a shortage of electric trains at peak time after the derailment of 323235 and 323231, Manchester Piccadilly to Alderley Edge and Hazel Grove services are worked by Northern DMU's. Before the derailments of the 2 units, it was expected that 2 trains an hour (one was an existing service, the other a proposed enhancement for the December 2008 revamp) would operate during the day between Manchester Piccadilly and Hazel Grove which would have been worked by Class 323s. However contingency plans have now been put in place which has resulted in the one service which already ran from Hazel Grove before the timetable change, being extended to Preston. The other proposed service has now been temporarily postponed.

Approximately 11 Units have now been repainted into Northern Livery. 323223 is a full paint job with 323224, 323228, 323229, 323232, 323233, 323234, 323235, 323236, 323237 and 323239 receiving vinyls.
