Network Rail's 950001 passes Didcot North Junction on 8 October 2010 with the 2Q08 08:25 Didcot to Banbury test train. You might think that it's going the wrong way for a Didcot to Banbury train, but as with all test trains the route is somewhat convoluted. Didcot to Severn Tunnel Junction and return, followed by a trip to Oxford via Didcot's West Curve. Back to Didcot (as seen here), then off via Oxford again, this time to Claydon Junction. Finally on to Banbury via a reversal at Oxford!
