+1000 on this. There's been a lot of woolly-minded mucking about with logos, corporate images and colour schemes. The flag logo was (almost) universally panned on various forums. The navy/white/snot green railcar livery had to be the worst example of an awful colour scheme,reminiscent of something a budget airliner would carry.
I wouldn't mind the DARTS so much, at least they're easily identifiable, looks reasonably well and it's a strong brand name.
