Ruston & Hornsby 165 series (including Class D1/3 and Class 97/6)

Ruston & Hornsby built hundreds of small industrial shunters between 1947 and the mid-1960s [1], they were known as the 165 series and had diesel-mechanical and diesel-electric transmission versions and also versions with both 0-4-0 and 0-6-0 wheel arrangements.

Although most went to industrial users two 165DS 0-4-0 shunters were sold to British Railways as the Class DY1, later renamed D1/3 [2]. Incidentally the prototype of this type of shunter was loaned to the LNER for a short period just before nationalisation for testing and evaluation though nothing more came of this at the time. The two D1/3s worked in the Stratford area until withdrawal in the late 1960s. One was preserved along with a good number of ex-industrial 165s which are a common sight on preserved railways.

Five 0-6-0 165DE shunters were also bought for departmental service by BR Western Region's civil engineering department, the first arriving in 1952 and the rest 1959 [3]. These were known as the Class 97/6 [4] and served until the late 1980s and early 90s at locations like Radyr, Taunton, Reading and Swindon [5] mainly shunting long welded rail trains [6]. Three of these locomotives have been preserved.
