The British Rail Class 755[5] is a class of bi-mode multiple unit train built by Stadler Rail for Greater Anglia. Part of the FLIRT modular train family, the trains first entered service on 29 July 2019 and are used on regional and local services throughout East Anglia.
History[]
In August 2016, Greater Anglia was awarded the East Anglia franchise with a commitment to replace all of the existing fleet with modern trains. As part of this an order was placed with Stadler Rail for 38 bi-mode multiple units that would join the FLIRT family.[6] These new trains were classified as Class 755s with the order composing of 14 three-car 755/3 sets and 24 four-car 755/4 sets with intention to replace the diesel Class 153, 156 and 170 fleets. Alongside the related electric multiple units of Class 745, the units are maintained at Crown Point TMD.[7][8]
The plan was for the units to be assigned to Greater Anglia's more local and regional routes throughout Norfolk and Suffolk, which include the Wherry Lines (Norwich to Great Yarmouth and Lowestoft) and the Bittern Line to Sheringham. The units would also be assigned to services on the Breckland Line and on the Ipswich–Ely line, as well as the Felixstowe and Sudbury branch lines.[9] Compared with the diesel multiple units they replace, the 755s have more seats, mains and USB sockets, faster Wi-Fi, air conditioning and improved passenger information systems. Because the trains have power-packs to contain the diesel generators, the floor is lower than usual, providing better accessibility to wheelchair and pushchair users.[10]
Operation[]
The first unit was delivered to the UK in November 2018 which gave an initial entry into service date planned for May 2019.[11][12] By May 2019, the trains had not been authorised to enter service yet and instead were given a service date for the end of June or beginning of July.[13] Following this, the trains were authorised to enter service on 30 May 2019 by the ORR[2] and the trains finally entered service on 29 July 2019.[14]
As more units have gradually entered service, it has allowed Greater Anglia to withdraw all of their diesel multiple units in favour of the 755s. All 38 of the units have entered service.[15][16] The delay in all units entering service has been caused by some initial multiple faults ("result of disruption due to a mixture of train faults and a problem with the signalling system on the Norwich-Sheringham line").[17]
Technical details[]
The Class 755 has three or four passenger vehicles, along with a separate power pack vehicle containing two or four[18] Deutz V8 16 litre[19][20] diesel engines and generators. All vehicles are linked by Jacobs bogies, with the end bogies being motored. The unusual layout for a British train allows a lower than normal floor level, enabling step free boarding at standard height platforms. Pantographs are mounted on the intermediate cars.[4]
Accidents and incidents[]
On 24 November 2019, unit 755416 was approaching a level crossing at New Rackheath, Norfolk at 45 mph (72 km/h) when the barriers lifted as the train was 200 m (660 ft) from the crossing and cars started crossing in front of the train. Emergency braking started immediately, but the train was unable to stop until 230 m (750 ft) after it had crossed the level crossing. A collision was avoided by a quarter of a second.
The Rail Accident Investigation Branch opened an investigation into the incident.[21] In response, Greater Anglia imposed a temporary 20 mph (32 km/h) speed restriction over six level crossings on the Bittern Line.[22][23] The cause of the incident was contamination of the track interfering with detection of the train by track circuits. The equipment was set to open the crossing 16 seconds after a loss of signal.[21]
As a result of the incident, flange lubricators were removed from the class.[24] The equipment operating the level crossing was reset to open the level crossing 99 seconds after a loss of signal. A computer program on the train was rewritten to remove a 10-second delay in the application of sand in the event of wheelslide. The frequency of Rail Head Treatment Trains over the Bittern Line was increased from weekdays only to daily during leaf fall season.[21]
On 30 January 2022, unit 755331 became stranded between Reedham and Haddiscoe due to a damaged track in the Wherry Lines along the Haddiscoe Cut. Six passengers were onboard the unit at the time with no fatalities or major injuries.[25] Following repairs, the line was reopened on 5 February.[26]
