This locomotive was built by the Yorkshire Engine Company to works number 2677 in 1960.
Formerly numbered DH1, it used to work at the St Helens glass works of Pilkington Brothers Ltd, who generously donated the locomotive in November 1982. The diesel is similar to the now defunct BR Class 02, except for not having vacuum brake equipment and other minor details. It has thus been restored in BR livery as D2870, the next one in the series.
The loco arrived in Preston on 30th March 1999, and D2870 is currently awaiting full restoration whilst being a worthy addition to the museum exhibits.
