Absolute madness?
You know what would be absolute madness... trying to unload hundreds of London - Manchester passengers on the narrow "through" platforms (13/14) whilst others board for Bolton/ Preston/ Carlisle/ Edinburgh/ Glasgow, in the short dwell time that trains have at these busy platforms... unless you are planning to replace eleven coach 390s with twelve coach 350s (so that the doors would be more suited to such alighting/ boarding)?
It "works" on the Birmingham route if you accept that there are lots of through platforms at New Street (rather than the bottle neck you get at Piccadilly), and you accept that passengers doing journeys like Crewe - Birmingham have to wait around fifteen minutes (xx:31 - xx:45) due to the Scotland - Wolverhampton path not matching up very well with the Wolverhampton - London path. Okay, there's space at Wolves for this, but what if you found that a Glasgow - Manchester - London service had to wait ten/ fifteen minutes at Bolton to meet the path of the existing Manchester - London service?
That's the problem with these "one a day" services... if they are well timed for business people then they are "a rip off" (since there are no cheap tickets available...
...but if they are timed off-peak (to use marginal resources and allow cheap tickets to London) then they are "useless" since they won't give sufficient time in the capital before you need to head home.
Really, we should be forgetting about these kind of "one a day" services and concentrate on good connections.
Agreed - I'm not sure what a Glasgow - Manchester - London service would "solve" (is there a huge demand from Glasgow to Stoke? Carlisle to Macclesfield?).
Even if you accept only a five minute wait in Manchester (rather than the ugly fifteen minutes in Wolverhampton on the Glasgow - Birmingham - London service) then you'll be talking a journey time of over an hour longer than the current Glasgow - London fast services (3h15 from Glasgow to Manchester plus 5 minutes in Manchester plus + 2h15 from Manchester to Glasgow = 5h35). Maybe if there were no Glasgow - Birmingham - London service then you could make a case for filling empty seats on a "via Manchester" service with cheap advanced tickets, but I can't see a case for a "via Manchester" and a "via Birmingham" service (as well as the fast hourly "direct" service).
Seems to be a solution in need of a problem.
Without wanting to get too involved in a discussion about local government boundaries, I think that a reasonable chunk of your four hundred thousand people will live within a ten mile radius of Wigan North Western (which has an hourly train to London taking under two hours). Regular trains from Wigan (Wallgate) to Bolton too.
The first thing I thought of, when I opened this thread, was the inevitable wailing and gnashing of teeth at the prospect of Manchester Airport losing more direct links
If Bolton *must* have a London service then that seems the most sensible way to do it (like the VTEC method of serving Sunderland). BR used to be good at this kind of resource allocation (e.g. I think that one of the reasons for the Highland Chieftan was the fact that there was an HST diagram that didn't start off Craigentinny until late morning whilst there was another that finished at Craigentinny at tea time - i.e. you could start the first duty in Inverness and extend the second duty to Inverness without requiring any more trains).
Does anyone know what time the last Pendolino leaves Longsight in the morning (i.e. if there's one that doesn't leave Longsight until eight in the morning then could this be run ECS from Longsight to Bolton and then in service from Bolton to Piccadilly where it would pick up the existing diagram towards Euston?). And equivalent time for the first Pendolino to finish its diagram in Manchester in the evening?
Agreed.
This would also have the benefit of freeing up frequencies/ patterns on other lines (e.g. at the moment the need to fit a slot from the Airport to Piccadilly means that the Cleethorpes service makes a 20/40 minute frequency with the Norwich service between Manchester and Sheffield) and allow links through Manchester (e.g. Sheffield to Blackpool was a direct service under BR).
Tying everything together into the congested Airport branch is a real waste of resources. The tail is wagging the dog.
