In the early 1990s, British Rail took the decision that running 2-car trains on rural routes was inefficient, and identified the need for single-carriage trains. Initially consideration was given to splitting the Met-Cam Class 156 units to form class 152 units, however due to various problems with the Class 155 units, the decision was taken to split these units instead.
Work was undertaken by Leyland Bus 1988 to 1989 at their Workington Dockside plant  The modifications included fitting a cramped cab to the B end of each carriage, making it extremely difficult to load a bicycle.
