Well that was definitely a day of two halves. It was great to be behind Tornado again, back where it belongs, as they say. The running between Durham and Berwick, also beyond Berwick until we were halted by the North Berwick stopper at Drem was superlative. Plenty of speedy running and impressive hill climbing aided a bit by the relatively lightweight (for Tornado) load of 11. Thanks to DBC and A1ST support crew for making it happen. The return was a disaster and very sad for Deltic devotees. I'll leave others to discuss why a locomotive straight off significant maintenance found itself on a charter without intensive proving activities (as was required for Tornado). Perhaps it happened and we missed it. Anyway, DBC did what it could to get people home and luckily the failure was somewhere that other trains could get by. My instant decision, with one or two others, to bale out immediately at Berwick was pragmatic. A 10 pm return to Doncaster was late enough for onward car travel southwards. As it turned out my actual return to Doncaster on IE28 was at precisely the time we should have been back on the charter, not two hours later.
