I would still like to drive a DMU. In particular the one at Quainton as I remember travelling up to the City quite a lot on those (in blue livery).
Unfortunately, GWR have a habit of swapping out driver experience courses, so even if I book a DMU I might not get it.
BTW I forgot one of several 03s in that list

Anyway, as Brian said earlier, didn't every schoolboy want to be a train driver at some stage?? I have added trams (well one narrow gauge at Seaton Tramway) - a half day course, the instructor, Mike Ward, was a distant descendant of Daniel Gooch. Had a short drive of a narrow gauge steam 040 at the Perrygrove Railway in Forest of Dean £5 for 20 + minutes and a tour of their engine sheds / workshops. Plan, sometime, to also do a course at Crich tramway, and a couple of other railways.
Another reason I can't afford to retire - all these experiences are not cheap!
Cheers,
