The Caledonian Railway 492 Class were a class of six 0-8-0 tank engines that were built for the Caledonian Railway, in Scotland by St. Rollox Works from November 1903 to January 1904.

These engines were described as mineral engines with large cabs with doors fitted. The 2nd axle had flangeless wheels. All members survived into LMS ownership.

History

Three locomotives, numbers 16950, 16952 and 16955, were allocated to Motherwell sheds during the days of the LMS, where the last of these were withdrawn in 1939. Another locomotive served as a banker for goods trains between Ninewells Junction, and Fairmuir and Maryfield yards, stationed at Dundee.[2]
