The Government had approved of four new diesel -powered motor coached & two trailer cars from existing stock suitably modified.The bodies were built at Islington Workshop, with motors & gearboxes obtained under contract. The first power cars, the 300 class were equipped with driving controls at one end only. The 24 - 800 class steel cars built for steam suburban servives in 1944-46 were modified and re-iussed to service as 860 class trailers for use in between two power railcars.The first three car set entered service on 6th. October 1955. By 1958 more railcars were starting to replace steam hauled trains. It was also apparent that the demand during the day, at night & weekends didn't justify three cars.
