In 1935, five BDSE carriages were converted from mail sorting use to baggage and van use. The new class letters were BCE, numbers 1 - 5.
Cars 1 - 5 were converted from BDSE 4, 1, 2, 6 and 7 respectively.
These vehicles saw use on passenger trains to replace the dead weight of large bogie vans.
With the change in passenger train rostering and new carriage sets, these cars were out of service by the mid 1980's. All were set aside for preservation with some running on chartered trips.
