British Rail Class 322

The British Rail Class 322 was a class of electric multiple unit passenger train built by British Rail Engineering Limited in 1990 for the Stansted Express service from London Liverpool Street to Stansted Airport, which opened in 1991. British Rail built a dedicated fleet of five four-car units for the new service, to the same basic design as the Class 321 but with a larger First Class area in the driving trailer and a different window arrangement. They entered service in a special white livery with a broad green band. After becoming surplus to requirements on the Stansted route the fleet saw further use with other operators, passed to Arriva Rail North and Northern Trains, and was replaced by Class 331 units, the last being withdrawn in May 2020.
