166207 arrives at Charlbury on 9 March 2017 with the 1P51 12:09 Hereford to Paddington GWR service. With a mix of Class 165, 166, 180 & HST traction, it is not always the case that the type of stock matches the length of journey over the Cotswold Line. Whereas this three car unit traverses the whole of the route, a few hours later a HST only goes as far as Moreton-in-Marsh, before returning to London.
