This was a German railbus last year at Bury Station. This was on the East Lancashire Preserved railway that runs up to Ramsbottom and Rawtenstall. The line is run by volunteers. This was part of a line that extended up to the Keighthly and Worth Valley railway. But a section was lost when Dr Beeching cut many of the railways in the early 1960’s when masses of steam trains were scrapped. Some of this was done when passenger use was light (eg school holidays). Lines were shortened and diesel trains were bought in (which sometimes proved unreliable). Info from my hubby.
