As described above steam railmotors were introduced in the area from 1905. This did not displace locomotives completely, and a number of 517 class 0-4-2T locomotives were in use with auto-trailers in the area. Both forms of train were referred to as railmotors and there is some ambiguity about the term; it is likely that both forms of traction co-existed. The goods service declined in volume considerably in the 1920s, and the goods trains were reduced at first to three days a week, and later to mixed trains only.
