In 2018 there are still many more five car Class 800s compared to nine car units, with the result that a lot of services on the Great Western Mainline are operated using a pair of five car units. Here however, one of the few nine car units (800304) passes Uffington on 25 September 2018 with the 1L50 10:36 Cheltenham Spa to Paddington GWR service.
