The British Rail Class 707 Desiro City is an electric multiple unit passenger train. Siemens Mobility built 30 five-carriage sets, initially leased by South West Trains. SWT's franchise successor South Western Railway began phasing them out from September 2021.[8] Twenty-eight sets are now in service with Southeastern having been transferred from South Western Railway by late 2023, with two sets remaining at South Western Railway.[9]

Background

In September 2014, South West Trains (SWT) announced plans to procure 30 five-car trains to expand its fleet to take advantage of significant infrastructure improvements that would allow the operation of ten-car trains. The Class 707 was the second product purchased for use on the British network from the Desiro City range, following the purchase of the Class 700 for Thameslink. All are leased from rolling stock company (ROSCO) Angel Trains.[10][11]

Construction of the first vehicles began in June 2015, with the first completed in March 2016.[12] The first two were completed as dual-voltage units with pantographs for operation on 25 kV 50 Hz AC overhead lines. This was a temporary arrangement for testing purposes at Siemens' Wildenrath test centre from May 2016.[13][14][15] They also operated in England in this configuration, being tested operating on the East Coast Main Line to Peterborough.[16]

The rest of the fleet was delivered with just 750 V DC shoegear for use on third rail electrified lines, but all will have the ability to be modified for dual-voltage use if required in future.[17] The first reached Britain on 9 December 2016.[18] Entry into service was originally planned for July 2017, with all 30 planned to be delivered by the end of 2017.[19] However, the first units entered service on 17 August, just three days before the South Western franchise was taken over by South Western Railway on 20 August 2017.[20][21] The last entered service in March 2018.[22]

Due to lower leasing costs becoming available, SWR decided it would replace the Class 707s with Class 701 Aventras from 2021.[23][24][25]

In April 2020, Southeastern signed a deal to lease the entire Class 707 fleet.[26] The first four units were transferred in January 2021,[27] with fourteen more following in small batches throughout the rest of 2021. The final twelve were expected to transfer to Southeastern by early 2022,[28] but in January 2022 South Western Railway announced that continuing delays to its Class 701 programme had resulted in it extending its lease on the remaining 12 units until late 2022.[29][30] By November 2022 the lease had been extended again, into 2023.[31]

Twenty-eight sets are now in service with Southeastern having been transferred from South Western Railway to Southeastern by late 2023, with two sets remaining at South Western Railway temporally.[9] The two sets at South Western Railway are planned to transfer to Southeastern in the future.[9]

Operation

SWT Class 707 at Reading in 2017

The Class 707 was introduced on services between London Waterloo and Windsor & Eton Riverside and London Waterloo and Weybridge via Hounslow, allowing the Class 458 units used on those services to be cascaded back to operations to Reading, which then allowed the Class 450 units to move elsewhere on the network.[32] When operated by South Western Railway Class 707 units were based at the Wimbledon Traincare Depot.[10]

The first Southeastern Class 707 units entered service on 27 September 2021.[28] Southeastern branded them City Beams, and deployed them on shorter-distance services from London Cannon Street and Charing Cross stations to Gravesend, Dartford, Sevenoaks, and Hayes.[33] Passengers praised the new trains for providing air conditioning and charging points for mobile devices, but expressed dissatisfaction that they were not fitted with toilets.[34] Southeastern noted in response that it was "not practical" to install toilets in the already-built units, and that the Class 376 units already in use on the same routes were also not fitted with toilets.[35]
