The Lancashire and Yorkshire Railway (L&YR) Class 23 is a class of 0-6-0ST steam locomotive. Their main use was for shunting and for short-trip freight working.

Construction[edit]

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.[1]

Ownership changes[edit]

EX-L&YR 0-6-0 saddle-tank No. 11429 at Low Moor Locomotive Depot 25 May 1947

The class was long-lived; the first loco was withdrawn in 1926 by the London Midland and Scottish Railway, but the last survived in use until 1964 with British Railways London Midland Region. 101 were in service at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.[1]

Preservation[edit]

One locomotive, L&YR 752 (LMS 11456), is preserved, having been sold to the NCB for continued operation is now[timeframe?] under overhaul back to working order.
