Caledonian Railway 908 Class

The Caledonian Railway 908 Class were 4-6-0 mixed traffic locomotives designed by John F. McIntosh and built in 1906, at the Caledonian Railway's own St. Rollox Works.

Overview

McIntosh developed six different classes of 4-6-0 for the Caledonian Railway:

large 49 and 903 Classes for express passenger traffic, with driving wheels
intermediate 908 and 179 and [184">Caledonian Railway 179 and 184 Classes">179 and [184 Classes|179] Classes for mixed traffic, with driving wheels
small wheeled 55 Class|55] and 918 Class|918] Classes for the Oban line and express goods traffic respectively

Only one batch of ten 908 Class locomotives was built, but the subsequent 179 Class was essentially a superheated version of the 908. All were originally delivered in the Caledonian's blue passenger locomotive livery. Two locomotives were named "Sir James King" and "Barochan", though these names were later removed.
Although most of the locomotives had cabs of the standard Caledonian Railway style with curved cut-outs on the sides, the last of the batch had a more modern style of cab with two arched windows on either cabside. Sources differ as to whether it was built in this form or whether the cab was modified early in the locomotive's life. Apart from No. 917 the only other Caledonian engines to carry side-window cabs were the 179 Class.

LMS ownership

The locomotives passed into the ownership of the London, Midland and Scottish Railway upon its formation in 1923. They were classified as passenger locomotives by the LMS and were therefore repainted into crimson lake livery, although this later gave way to lined black. Oddly, the very similar 179 Class were treated as goods engines by the LMS.
They were displaced by new LMS standard locomotives such as the "Crab" 2-6-0s and were withdrawn for scrap between 1930 and 1935.
