I’ve mentioned several times Burnham’s apparent lack of interest in the Castlefield corridor problems. He only seems interested in cycle lanes and GMPTE’s “Mancrail” aspirations...
In fairness to the guy, he seems to be focussed more on the kind of things that the Manchester Mayor can control.
The Castlefield corridor is a "national" issue (in that it affects trains to Glasgow/ Newcastle/ Norwich/ Llandudno etc) - any attempt to tackle the corridor in the short/medium term will mean removal of some of these long distance links (and spending hundreds of millions of pounds on bringing it up to the standard that people on this Forum want) would mainly benefit long distance passengers, so it's less of a priority for the people who vote for the Manchester Mayor.
That's a fault of the system, not a fault of Burnham. Castlefield is something for TfN to sink their teeth into, or maybe even the DfT.
If I were Mayor of Manchester, I'd be looking at the kind of things that my constituents wanted, which is why bike lanes and Metrolink will always be more interesting than tackling a national bottleneck so that we can run more/reliable services to places like Glasgow/ Newcastle/ Norwich/ Llandudno.
I hear these “Manchester gets everything” complaints regularly from work colleagues from Yorkshire. The Chord benefits people from Yorkshire and the North East by providing direct links to Manchester Airport. It does very little for Manchester just creates rail chaos. Services to Piccadilly from West Manchester and Lancashire have been reduced to make space for the Yorkshire airport trains.
Those links to the Airport were there already - there aren't currently any additional services to the Airport due to the Chord opening.
The plan was that diverting them that way would benefit shorter distance commuting into Manchester (additional paths for Hazel Grove, Macclesfield, Greenbank) due to the Scarborough - Liverpool service not closing the entire Piccadilly throat down when it crossed from the Guide Bridge side to the Oxford Road side. When you look at it like that, Cheshire was due to get a big benefit from the Chord but no change at the moment for Yorkshire (there are
plans for a Calder Valley - Airport service over the Chord, but that's not happened yet and would require additional DMUs and additional paths - both of which are in short supply!).
