The Class 23 0-6-0ST locomotives were rebuilt at Horwich Works by Aspinall between 1891 and 1900, using the frames, wheels etc. from earlier Barton Wright 0-6-0 tender engines, built 1876-1887. 230 were so converted.
The class was long-lived. The first loco was withdrawn in 1926 by the London Midland and Scottish Railway, but the last survived in use until 1964 with British Railways London Midland Region. 101 were in service at Nationalisation, 20 still in service in 1961.
One locomotive, L&YR 752 (LMS 11456), is now preserved, having been sold to the NCB for continued operation and as of October 2012[update] is nearing the end of an overhaul to bring it back to working order by its owners, The Lancashire and Yorkshire Railway Trust, a Registered Charity reg no 1002627.
