 Although Barton gained a reputation for having a varied fleet of vehicles during the 1950s and 1960s, from 1946-9 the vast majority of new chassis were from Leyland, and virtually all coachwork was from Duple.The Duple A type coach was chosen for PS1 Single deckers, some featuring a more compact front-design allowing up to 39 seats in the then maximum overall length of 27 ft 6in.The 40 postwar double deckers on PD1 or PD1A had an updated version of the forward entrance lowbridge body with more brightwork and power-operation for the entry door.
