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 (number 917) 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.

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.

They were displaced by new LMS standard locomotives such as the "Crab" 2-6-0s and were withdrawn for scrap between 1930 and 1935. source: BritishSteam[3]
