A two-car set weighed 53 tons and could carry 130 passengers.
Liveries
Original plans had the vehicles considered as coaching stock, the build specs show then as to be painted in Carmine and Cream (as the ex-GWR railcars were). However before delivery a change was made to consider them as Motive power and they were instead scheduled to be painted in green.
The sets were delivered in BR engine green with yellow lining above the windows and at waist level. They carried the loco style of British Railways logo with the lion sitting atop a wheel, facing the cab. Delivered without speed whiskers, they would be added later, and these would be later replaced by yellow panels below the cab windows. As the vehicles were withdrawn in early 1964, this was too early for any to receive rail blue.
