British Rail Class 139 is the TOPS classification [5] for PPM60 model lightweight [6] [7] [8] railcars built by Parry People Movers, [6] for use on the British rail network. The class were originally built in 2008 for operation on the Stourbridge Town branch line following an extensive trial with a prototype registered as a Class 999 unit.

Contents

The first newly constructed Class 139 was shown on 28 June 2008 at the Tyseley Locomotive Works Open Day. The full fleet of two units entered public service on the branch line in June 2009.

Technology

The Class 139 units are typical of the Parry People Movers concept, in that they utilise flywheel energy storage to recapture and supply the motive force for moving the vehicle. [9] The flywheel captures the vehicle's kinetic energy when the brakes are used, [9] and re-uses the energy for acceleration. This eliminates the need for a large diesel engine. The small onboard engine (fuelled by LPG) is used to initially bring the flywheel up to speed, to add speed to the flywheel after the vehicle is started in motion, and to provide power for the onboard systems. [9]

The concept of using the lightweight [3] [6] [7] [8] railcar dates from 2006, when a year-long pilot scheme began on the Stourbridge Town branch line on Sundays, using a PPM50 unit constructed in 2002 and numbered as 999 900 under TOPS. The success of this trial led to the provision of regular services using the technology in the franchise plans for the new West Midlands franchise. Following the award of the franchise to London Midland, it placed an order for two PPM60 units with Parry People Movers, through Porterbrook leasing, with the service itself operated by Pre Metro Operations.

These two units are 139 001 and 139 002, composed of vehicle numbers 39001 and 39002 in the British carriage and wagon numbering and classification system. The vehicles are mechanically similar to 999 900, but are approximately one metre (yard) longer. They were intended to start operating on the Stourbridge Town branch in 2008. [10] In January 2009 it was confirmed that 139001 was still undergoing testing at Chasewater Railway and 139002 was still not completed. [11]

Despite the difficulties in the commissioning of the two Class 139 units, London Midland consistently outlined its faith that they would be ready to enter service. In March 2009, it was announced that the first unit had received its passenger certification from Network Rail, allowing it to carry passengers. London Midland said it would begin a phased entry into service, starting with weekend operation in April, leading up to a full service by the timetable change in May 2009. [12] Until then, London Midland temporarily returned a Class 153 to operating the branch service. [13]

139 002 officially entered service on 29 March 2009 as part of the type's phased entry. This unit had previously worked in full service, including all-day on Monday 11 May 2009 and previously had worked all morning services during February/March 2009. [14] In May 2009, the first unit, 139 001, was finally delivered to Stourbridge, with 999 900 removed at the same time. [14] Test unit 999 900 had been on the branch line between 2005–2009. [14] At the point of introduction, they displaced a single Class 153 DMU that was previously allocated to the branch line. By December 2009, the 200,000th passenger had been carried by the railcars. [4]

In 2010, a trial service was planned between the Mid-Hants Railway, a heritage line in Hampshire, and Go-Op, a planned open access operator, which would see the former 999 900 restored to its original designation as Parry Car No. 12, operate peak time trains between Medstead and Four Marks and Alton, intended to connect with South West Trains services to London in the morning and from London in the evening. [15] Problems with the vehicle during testing meant that this project was postponed. As a consequence, the vehicle, since purchased by Lightweight Community Transport, [16] underwent a major rebuild to bring it up to Class 139 standard, and was renumbered as 139 000, then later 139 012. [17] [18]

Future

Parry People Movers is using London Midland's purchase of the Class 139 for the short Stourbridge line to promote the PPM concept for other lines that are short and essentially separate from the main railway network as a means of reintroducing rail travel to areas that have seen it curtailed. [19] PPM indicated that it intended to use a variation of the PPM60 model, to be known as the PPM220, to bid for the contract to build a small fleet of experimental tram-trains for use on the Penistone Line, and for the new generation DMUs intended as part of the government's rolling stock plan. This will entail an articulated unit, with a pair of PPM60 variants at either end of a fixed passenger unit—the whole unit will be capable of accommodating up to 220 passengers and travel at up to 60 miles per hour (100 km/h) on railways or 50 miles per hour (80 km/h) on tramways. [20] The Penistone trial however was cancelled before a bidder was selected, and was replaced in September 2009 with an electric Rotherham-Sheffield trial. [21]

Unit 139012 is planned to be used as a technology demonstrator following its upgrade, with testing planned initially for the Chasewater Railway, a 2-mile (3.2 km) long heritage line in Staffordshire, before further tests on the much longer, double track Great Central Railway in Leicestershire. [22] The intention then is to transport the vehicle to test a more frequent service on the Ellesmere Port to Warrington Line between Ellesmere Port and Helsby. [22]

In cooperation with Lightweight Community Transport, Parry People Movers is developing a new, four–axle bogie vehicle with a more powerful diesel engine and greater passenger capacity that it plans to market as the flagship product for use on branch lines, which it is classing as 139/1 (with the original, two axle units being 139/0). The success of the Stourbridge units has led to more interest in using such vehicles elsewhere by train operating companies, with at least one pre-qualified franchise bidder in the 2012 round including the procurement of Class 139s in its franchise bid.

The Weymouth Harbour Tramway was a heavy rail line running entirely on the streets of Weymouth, Dorset, England from a junction to the north of Weymouth station to Weymouth Quay station at Weymouth Harbour. Built in 1865, it was last used for timetabled British Rail services in 1987 with the last special train running in May 1999. The line was dismantled in 2020-21. Street running tracks still remain but very little. The link to the mainline still exists, but only down to the street.

A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
