 The locomotives were initially allocated to the G&SWR's Carlisle Currock shed for goods trains to Glasgow, Greenock and Ayrshire.Under LMS ownership they were transferred to the former Caledonian Railway shed at Carlisle Kingmoor, after which they were also used on runs over the Caledonian Main Line and occasionally the Settle-Carlisle Line.As new LMS 'Crab' 2-6-0s took over their duties in the early 1930s most were displaced from Kingmoor to various LMS sheds throughout Scotland, with some even operating from Inverness for a time.
