Like a lot of ideas on here, it all sounds nice until you try to unpick the details.
First of all, would going back to the old timetables mean no TPE services over the Ordsall Chord? All that money spent on connecting Piccadilly with Victoria and we decide to abandon it? Can you imagine the reaction?
Secondly, do you go back to the exact service pattern that the Huddersfield line used to have? With a lop-sided fifth TPE service? Or, if we are simplifying the timetable, do we go back to a simpler four/hour? Newcastle loses half its TPE services – does it lose the Manchester Airport or Liverpool service? Either will inconvenience people.
Assuming that there’s a half hourly Liverpool service via Chat Moss (as you’re not going to be able to path one over the Piccadilly throat), are you planning on having a half hourly Airport service reversing at Piccadilly or using the Ordsall Chord? One would mean splitting the services between two stations at Manchester, one would mean giving up on the Chord.
Or, if the plan is to produce a resilient timetable with sufficient layover time (which may mean having a spare DMU at Scarborough etc, a layover of over sixty minutes) then why not give up on the Airport leg? The average passenger loading is only just over thirty per service at the Airport, there’ll still be seven other services per hour from Piccadilly to the Airport. If the idea is to provide reliable services on the TPE core then you surely have to consider abandoning the extremities, temporarily?
Another problem (on a line where disability concerns have seen the Pretendolino plan abandoned) is that you’d be replacing modern 185s (with accessible toilets and other facilities) with 1980s 150s (or even potentially Pacers) at local stations between Leeds and Manchester – if the plan is to bring back the old Northern stopping services. Can you see that going down well with passengers who are just getting used to being able to use the trains at their local stations?
Then there’s the issue of whether Northern do have spare DMUs (and spare staff) to run the stoppers? I don’t know what the stock/ crew were cascaded to but it doesn’t look like they have lots of spare resources to tackle TPE’s problems with – they can’t solve their own problems at the moment.
Plus some stations will lose their direct train to a big city (e.g. Marsden to Leeds, Batley to Manchester), which could attract more negativity.
I think it’d be better to address the specific clashes and conflicts – e.g. one early morning service from Scarborough to the Airport seems to run okay until it reaches the Chord, but then lose a lot of time heading east towards Piccadilly (and is often terminated there). As this isn’t happening to every service over the Chord, presumably there’s something specific affecting this service – should it be terminated at Victoria instead?
Scarborough-bound services seem to lose time heading to the coast. Would it be better to terminate half of the Liverpool – Scarborough services at York, with an equivalent bi-hourly shuttle from the terminating platforms at York towards Scarborough, to avoid some clashes over the flat ECML and ensure that Scarborough gets some guaranteed services? Maybe do the same with some Middlesbrough services too? But try some small adjustments rather than the baby/bathwater approach that some on here seem to like.
I know that nostalgia is always flavour of the month on here, but I didn't expect nostalgia for just a few weeks ago!
