After NXEC fell over, DOR was working well. They were innovative, they were fresh, they were profitable, they were stable
They were innovative and fresh? Well, they gave up on the NXEC plans for daytime services to Lincoln and Harrogate, meaning that the leased 180s spent their days pottering around Manchester on loan to Northern.
Profitable? Well, everyone operating the ECML franchise ought to be handing a premium to the Treasury - AIUI Stagecoach/Virgin were paying more than DOR managed - DOR are often praised for being "profitable" but they didn't have a benchmark/ commitment so paying *anything* back was seen as good enough for them.
Stable? Well, there were no franchise commitments to stick to, there were no shareholders to worry about, there was no benchmark for success/failure, so it's probably quite easy to be "stable" in such circumstances.
Apart from that, they gave away lots of "free" tickets and some people think that the website was nice.
Maintenance cutbacks in their six years in charge? I don't know. I've seen people suggest that the fact that VTEC require a couple of 90s to maintain services was linked to DOR's handling of the 91s but that could just be because the 91s are getting towards the end of their lives and the "bathtub curve" means that they were bound to become less reliable, regardless of who had looked after them.
I'm not saying that they were a
terrible operator, not a
great one - they just abandoned the ambition of NXEC, stuck to the basics, I'm not sure why they are so eulogised on here (other than a chance for political point scoring from people seeking a reason to criticise private operators).
If DOR had been a six year franchise run by another bus operator/foreign Government then I don't think many people would remember them a decade later - fairly dull/functional livery, fairly unambitious operations, some nice perks for First Class passengers but probably not in the top/bottom ten of TOCs we've had since privatisation. BUT, as poster boys for Westminster-controlled operations, they are elevated to special status.
