Obviously, the single deckers must have been getting full enough to get an upgrade (and in the X1s case, a full upgrade rather than partially but the Citaros do only have 40 seats).But the point is, if any service is having standing loads on multiple journeys, double deckers should be considered over single deckers when investment is being planned.
As someone who has no idea of the official figures, I'd argue Sunderland's 'flagship' routes are indeed services 16 and 20 - where's the double deckers?
