I agree, the 36/42 being merged would be a brilliant idea. I've briefly thought of suggestions similar to those that have been suggested already, but I hadn't ever come close to this one!
A merge of those two "SimpliCity" services would be great. I know the 42 is regularly used, but I haven't seen the 36 being used to a great extent in recent weeks when I've been out photographing buses in the Town End Farm area... Perhaps if these were merged, those two different kinds of passenger numbers would cancel each other out and the final service would stand more of a chance of running on-time?
