I believe the plan is
Liverpool - Newcastle 1tph fast
Liverpool - Scarborough 1tph fast
Man Air - Saltburn 1tph via Ordsall then Hudds/Leeds only
Man Air - York 1tph via Ordsall then Hudds/Leeds only (to be extended to Newcastle if/when capacity upgrades north of York are actually done)
Man Picc (Shed) - Hull semi-fast 2tph (Stalybridge, Hudds, Dews, Leeds)
As it will be 8-10 years before this new fleet can be built, tested and fully deployed much can happen in the meantime, not least demand for rail.
I have been using the roads between Sheffield and Newcastle and Hull for the last 50 years. Rarely have I used trains. To nearer Manchester? I can only recall using the car once. Why the difference?
It's relative convenience at both ends of the journey. Going to Manchester I can catch a train at least hourly from a station within walking distance of my home. My visits to Manchester (or Liverpool) are for city centre based events.
Going to Newcastle or Hull requires a change of train in Sheffield and I'm travelling for social reasons well away from the city centres.
I used to use the car to Leeds, even for city centre business meetings. Not any more. The M1 has got wider and busier, roads to the M1 are very congested and parking is far more difficult. London has always been a train trip for me (although before the M25 I drove through to Surrey).
Our trip to Newcastle for this year's Great North Run reminds me of how much more congested our roads have become generally, and every day. The increased distances being travelled by more people by road over the last 50 years should encourage greater use of longer distance rail.
For some journeys that's happening but nothing like as much as our increasing population is taking to roads. Which brings us back to TRU, TPE, GBR and the DfT. Where, when and what units are to be deployed? These new units are a relative drop in the ocean when it comes to satisfying our increasing demands to move around the country.
And then to 9 car Elizabeth line trains and Thameslink at 12 car, both rammed full through London at peak hours, even from personal experience at midnight!
Earlier this week roads into Manchester Airport were gridlocked feeding back onto the local motorway network. Drop off charges are high yet cars keep coming. We need better rail connections and that's what TPE are all about.
5 car trains are better than 3 but there's a serious lack of effective capacity to satisfy greater ambition. There aren't enough paths to run many more trains reliably. There aren't enough platforms long enough for trains over 6 car, some even for that. Access to many stations is restricted with limited parking nearby and poor integration with bus routes and services. Drop off can also be congested with fees starting to copy those at airports.
These new trains themselves are a very small part in a highly complex scenario that will change many times over the next 50 years before they should have been replaced!
