Hornby R3898TTS BR Class 08 0-6-0 3817.
Designed by BREL and built at Horwich Works, D3817 entered traffic on 18 March 1959. After being allocated to Newport for just overs ten years, the locomotive spent its entire British Railways service life in the south. It was initially based at Ashford and then Eastleigh, during which time it was renumbered as 08650. Foster Yeoman purchased the locomotive in August 1989, transferring it to operations on the Isle of Grain where it continued operation into Aggregate Industries' ownership. Now owned by Mendip Rail, 08650 has operated under private ownership longer than it did under that of British Railways.
This model is 124mm (length) and is decorated in BR Rail Blue livery.
