This video from oorail.com looks at the BR Mk1 Sleepers from Bachmann. Bachmann recently released the Sleeper First (SLF) and Sleeper Second (SLSTP) in Inter-City BR Blue and Grey livery and BR Maroon livery. This video looks at the Inter-City version which is 39-501 (SLF) and 39-503 (SLSTP). BR Mk1 sleepers were used to provide sleeping accommodation to passengers during long overnight travel. There were no BR Mk2 sleepers, and the BR Mk1 sleepers were eventually replaced with BR Mk3 sleepers in the 1980s. The introduction of high speed trains resulted in the scaling back of the BR sleeper service.
