Longest route in/through Merseyside?
Any ideas what the longest in terms of distance (local stopping) bus service within Merseyside, (or calls through Merseyside)?

My contender is the Cumfybus 811, dep 11:52 SSuX Leasowe - Broughton arr 13:44. Probably the best pence per mile ratio too, just £1.10.

Probably would have said the X2 Liverpool-Preston before the route got split to Southport, at least, on paper.
