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 unit Stadler Flirts. The order is composed of 14 three-car and 24 four-car sets and replace the Class 153, 156 and 170 fleets.
The first unit arrived in the UK in November 2018; entry into service was initially planned to begin in mid-May 2019, but during May it was delayed to the end of June or early July. On 30 May 2019, the ORR authorised the 24 Class 755/4, and the first entered service on 29 July.
All are scheduled to enter service in 2019. They will be maintained at Crown Point TMD. Faults with the vehicles discovered during their introduction led to staff at Crown Point awarding them the nickname "Basils", after Basil Fawlty.
Accidents and incidents
On 24 November 2019, a unit of the class was approaching a level crossing at Thorpe End, Norfolk at 45 miles per hour (72 km/h) when the barriers lifted as the train was 220 yards (200 m) from the crossing and cars started crossing in front of the train. Despite emergency braking, the train was unable to stop before the crossing. A collision was avoided by a quarter of a second. The Rail Accident Investigation Branch has opened an investigation into the incident. In response, Greater Anglia has imposed a 20 miles per hour (32 km/h) speed restriction over five level crossings on the Bittern Line.
The Class 755 has three or four passenger vehicles, along with a separate power pack vehicle containing two or four Deutz V8 16 litre 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, this allows step free boarding at standard height platforms. Pantographs are mounted on the intermediate cars.
