Some operators made heavier weather of Covid than others. The restrictions in place in Wales were more onerous than those in place in England, but at no point did they forbid in-cab training, any more than they forbade ambulance crews, airline pilots etc. from being in a shared environment. TfW restricted themselves to a degree no other TOC did.That is incorrect, operators are now cooperating again on route learning, the lifting of different covid restrictions in Wales just meant that timescales were in the end too short for this summer (the summer timetable starts this coming weekend).
I’m not sure why operators would try and find an ‘excuse’ to make route learning harder. Covid was not an excuse, it was a global pandemic.
