CrossCountry came to the aid of GWR on 10 May 2021, by lending an HST set and some Voyagers to cover for GWR's Class 800s, which had been withdrawn to check for underframe cracks. 43207 is pictured passing Thingley with the 1Z14 05:34 Plymouth to Swindon service. The set (with 43239 on the other end) then spent the rest of the day working Swindon to Bristol Temple Meads shuttles.
