20142 was in use during the Llangollen Railway's Diesel Gala on 20 May 1995. It is seen here pulling away from Berwyn station with the 12:00 Llangollen to Glyndyfrdwy service, with the River Dee in the background. It would shortly lose its tatty BR blue livery in favour of green, which it retained until recently (with either full yellow ends or small warning panel), until reappearing again in blue.
