I see... I guess Heaton Chapel, Levenshulme and Cheadle Hulme are stuck with the messy pattern indefinitely then, which seems odd considering the new service pattern means that paths for these services should no longer need to match up across both sides of Manchester. To my mind this should mean more flexibility, not less, but then again, I'm no expert so I shall assume those responsible have done their best to fit everything in.
On the plus side, reliability should improve with less going through Castlefield. The trains are also less bunched in the southbound direction, and the odd arrangement where trains stop at one but not the other of HTC and LVM is gone entirely.
It's mostly gone from the small stations on the Airport line as well. Two stoppers per hour with the Heald Green, Gatley and East Didsbury each getting one "fast" makes a lot of sense. Unfortunately they're still unevenly spaced, but considering the amount of different traffic that line has to cope with with just two tracks and most of the trains heading for a terminus which is rather undersized, it's a miracle the service works at all.
