The new Chiltern Railways livery made its mainline debut on 25 September 2025, when 68020 and a Mk5a set made a series of test runs from along the Cherwell Valley, after travelling up from Eastleigh. The early running 5Q71 12:54 Didcot Parkway to Leamington Spa is pictured passing Wormleighton Crossing. The dark blue livery on this end of the loco looks almost black in this severe backlighting. Driving trailer 12805 is bringing up the rear.
