37219 slowly approaches Charlbury station on 2 December 2015 with the 1Q15 09:08 Derby RTC to Derby RTC (via Oxford) Network Rail test train. As if the yellow Network Rail vehicles were not bright enough, the recent handing of the contract to Colas has made the whole train even more colourful! 37175 is on the rear of the train. The train would have to wait in the station for a few minutes (as booked), as the 1P43 11:22 Worcester Shrub Hill to Paddington Turbo unit was still on the long single track section to Wolvercote Junction.
