20137 passes a fine show of Rosebay Willowherb (Epilobium angustifolium) near Hailes on 11 August 1995, whilst working the 13:00 Toddington to Far Stanley freight. This was one of a number of demonstration freights run during the Gloucestershire Warwickshire Railways Diesel Week. Although very rare in the later days, such as depicted here by the Railfreight livery, short freights headed by a single Class 20 were relatively common in the early days of the class.
