8 castle class locomotives currently preserved. Ignoring Thornbury Castle for a moment. 1 is on static display at Swindon. 2 are at didcot railway centre, including the only operational example that does not run on the mainline. 3 are in the care of Tyseley. 1 is with the lovely folk at LSL. If I really wanted to see an operational castle but couldn't afford a mainline rail tour my options are very limited. Can anyone involved with didcot, night owl, GWS, or indeed any of the critics on the internet see any point in restoring a third example for Didcot? No. But before didcot/4709/GWS acquired Thornbury Castle it was never being restored for use at Didcot. It was being restored to regularly run on a railway much longer than the demo line at didcot. By my reckoning that was a unique prospect we appear to have had collectively taken away from us.
