The Caledonian Railway 55 Class were 4-6-0 mixed-traffic locomotives designed by John F. McIntosh and built at the railway’s St. Rollox works in Glasgow in 1902-1905. The class was intended for use on the Callander and Oban line and were sometimes known as Oban Bogies, a nickname they shared with the earlier Brittain 179 Class 4-4-0s and the subsequent Pickersgill 191 Class 4-6-0s, all of which were built for use on the same route. ==Design== The Oban line had numerous short but steep gradients along with tight curves and lightly constructed bridges, and was therefore a challenging route to operate. McIntosh therefore designed a small 4-6-0 which was essentially an elongated hybrid of his 812 Class 0-6-0 and Dunalastair series 4-4-0 types.〔Atkins, C. P. (1976), ''The Scottish 4-6-0 Classes'', Ian Allan, p.45〕 The class featured a particularly short driving-wheel wheelbase to cope with the curvature of the line, and short tenders to enable the locomotives to fit onto the existing small turntable at Oban shed.
