Class 322 (BREL York Stansted Express)

The Class 322 was a variation of the Class 321 built for the Stansted Express between London Liverpool Street and Stansted Airport. The chief difference between the 322 and the 321 is that the former has a larger first class seating area in the DTCO with different windows. They were fitted with low density seating and given extra luggage space [1]. The Class 322 was the last class of electric multiple unit to be based on the Mark 3 coach.
