68018 & 68023 pass Charlton-on-Otmoor on 3 August 2026 with the 5O86 09:52 Wembley to Eastleigh Chiltern Railways ECS. I was expecting this to just be a Chiltern Railways Class 68 and Mk5a set, so this double header was a definite bonus, especially as the lead loco is wearing unbranded DRS blue livery.
