Does anyone know why Skyliners are running some X61's?
I agree that the Tridents were a long overdue and necessary step (no pun intended) to low-floor operation.
However, judging from what Paul McGill has said, they simply cannot cope with the route. Therefore I would suggest replacing them with new Scania/E400 deckers and cascading them elsewhere, eg. Lancaster to see off the 4 Leylands and a few Volvo Olympians, which could then be divided between Lillyhall and Barrow to displace more Leyland Olympians.
J126 and J127 XHH still do the X35s in place of tridents.
