221126 races through Culham station on 25 February 2018. This is not quite the mundane passenger service that it appears to be, but is in fact the 5O16 15:15 Oxford to Bournemouth ECS. This was a VSTP (Very Short Term Planning) substitute for the cancelled 1O16 14:16 Oxford to Bournemouth CrossCountry service. The line north of Oxford was closed for engineering works, but that still does not explain the cancellation.
