The British Rail Class 507 is a type of electric multiple unit (EMU) passenger train built by British Rail Engineering Limited at Holgate Road carriage works in two batches from 1978 to 1980. They are a variant of British Rail's standard 1972 design for suburban EMUs derived from PEP stock, which eventually encompassed 755 vehicles over five classes (313, 314, 315, 507 and 508). ^[5] They have worked on the Merseyrail network from new and continue to do so, having been refurbished by Alstom's Eastleigh Works.

The Class 507 units are all now at least 43 years old, and, following the withdrawal of the Class 313 fleet in 2023, are the oldest units operating on the mainline rail network in Great Britain. ^[6] However, the even older 1972 Stock and 1973 Stock are still in service on London Underground's Bakerloo and Piccadilly lines.

History

With the Class 502 units life-expired, unable to cope with the demands of the new Link tunnel and approaching 40 years old, by 1977 a replacement was sought. Owing to the success of the Class 313 fleet on suburban services from King's Cross, four sets were temporarily transferred to Merseyside and based at Hall Road TMD. Sets 313013/063 ^[7] were used for clearance trials on the Southport, Ormskirk and Kirkby-Garston lines. The results showed that a similar type of stock would be suitable for the Merseyrail Northern Line.

Initially, 47 sets were ordered (507001–507047) but cost issues forced this number to be reduced to 38 units, then 30 by early 1978 when the first sets were under construction. Ultimately, 33 units were built between September 1978 and October 1979. The first set was delivered to Birkenhead North depot during September 1978, ^[8] with the first test run taking place on 9 October 1978. ^[8]

On 25 October 1978, a Royal Special involving units 507001 and 507002 conveyed The Queen and several other VIPs on a special service between Moorfields and Kirkby. Following the journey, she declared the new-look Merseyrail network officially open. ^[9] The first passenger working occurred on 1 November 1978, with unit 507001 working the 07:39 Southport-Liverpool Central with a commemorative headboard. ^[8] It worked between Liverpool and Southport for the remainder of the day, while unit 507002 operated between Liverpool and Ormskirk. Further Class 507 units steadily entered service and the Class 502 was, in turn, withdrawn. By mid-1980, Northern Line services were entirely in the hands of the Class 507 and all of the sets were in service by October 1980. ^[8] A host of new liveries appeared following sectorisation of British Rail.

Following privatisation, the Class 507 units were used interchangeably between both the Northern Line and the Wirral Line, working a further four routes regularly. The remaining 32 units were refurbished by Alstom Eastleigh during 2002–2005. They received new interiors, CCTV, light clusters dot matrix displays and the 2+3 seating was replaced with 2+2 seats. ^[10] Unit 507033 was the last Merseyside set to be refurbished, entering service having been named Cllr George Howard in August 2005. ^{[11] [12]}

A farewell tour for the Class 507 is planned for Summer 2024, the tour is planned to be operated using units 507001 and 507003. ^[13]

Description

Class 507 units are formed of three cars, and numbered 507001 to 507033. ^[14] Original plans were drawn up for 47; later 38 Class 507 units to be built, but costs enforced a reduction in the number. Sets are made up of two driving motor cars ('A' DMSO with the compressor; 'B' BDMSO with the battery) and a trailer.

Originally, each three-car set seated 234 passengers, this figure being reduced to 222 following interior modifications during the 1990s. After the introduction of high back seats during refurbishment in 2004/2005 this was reduced to 192 with space for cyclists and disabled people improved.

The Class 507 (and 508) replaced LMS-designed Class 502 EMUs on the Northern Line and Class 503 EMUs on the Wirral Line.

Current operations

From new, all Class 507 units have worked the Merseyrail network. Sets have been used interchangeably between the Northern Line and the Wirral Line since 1997, so work the following:

Northern Line

• Southport – Hunts Cross line
• Ormskirk line
• Kirkby line

Wirral Line

• New Brighton line
• West Kirby line
• Chester line
• Ellesmere Port line

Replacement

Merseyrail expected that the Class 507 and 508 units would be withdrawn around 2014 and replaced by a new EMU, but this was postponed following a refurbishment. In May 2012, Merseytravel announced that it had formally begun a project for replacement. ^[15] The fleet received a refresh package including external re-livery, internal enhancements and engineering work. ^[16]

In January 2016, Merseytravel announced the short list of companies bidding to build new trains which will replace the Class 507 and 508 on the Merseyrail network. ^[17] In December 2016, Merseytravel announced that Stadler had won the £460 million contract and that the new Class 777 trains would be delivered from summer 2019 with all the old trains replaced by 2021.^{[ citation needed ]} The first unit entered service late in January 2023. ^[18]

Preservation

In March 2024, the Class 507 Preservation Society reached an agreement to preserve 507001. ^[19]

Accidents and incidents

• Unit 507022 was written off as a result of a serious collision with unit 507004 at Kirkdale TMD on 30 September 1991. ^[20] The DMSO vehicle 64388 from 507022 was used to replace the corresponding vehicle in 507004, while the BDMSO vehicle was used as a replacement for a written-off vehicle in Class 314 unit 314203.
• Unit 507029 was damaged in a collision with buffer stops at Kirkby in 1991.
• Unit 507032 was damaged in a collision with buffer stops at Kirkby in 1997.
• Unit 507019 was damaged in a collision with buffer stops at West Kirby on 11 January 2007. ^[21]
• On 30 June 2009, unit 507002 ran away from Kirkdale TMD under power –but not under the control of a driver – and reached an estimated speed of 30 mph (48 km/h) before being derailed at a set of points that joined the depot to the main line. ^{[22] [23]} Following the derailment, the train came to rest blocking the main line at a position where a passenger-carrying train had passed only seconds before. ^[24] The incident was caused by a failure by depot workers to apply to the train's brakes before isolating the train from the traction current supply when conducting diagnostic testing. When the isolation was subsequently removed, the train's traction supply was re-energised and it proceeded to move under its own power. ^[24] Merseyrail pleaded guilty to breaching the Health and Safety at Work etc. Act 1974 by failing to ensure that its workers met the required safety standards, and was ordered to pay a fine of £85,000 and legal costs of £20,970.15. ^{[24] [25] [26]}
• On 13 March 2021, unit 507006 was the lead unit of a train that overran the buffer stop and derailed at Kirkby station. Twelve people sustained minor injuries and the unit was written-off. ^[27] The Rail Accident Investigation Branch found that the driver failed to apply the brakes at the appropriate time, due to being distracted. ^[28]
