Found a really interesting link about the future of certain Transpennine services from the elventh item in the reference section of the Wikipedia page about TransPennine Express. The link is to a Government website page, titled,
Future of Northern and TransPennine Express rail franchises.
I have read the entire document but there are plans afoot to split the East Anglia to Liverpool service, currently run by East Midlands Trains at Nottingham so that Transpennine run the service from Nottingham to Liverpool giving Transpennine all the express services from Sheffield to Manchester, I would imagine.
As regards the Scarborough to York line, there were different possibilities mentioned:
- Scarborough to York
- Scarborough to Leeds
- Extending the service between Blackpool and York to run as far as Scarborough
- Maintaining the status quo by running a service from Scarborough all way across the pennines under the wires.
There is a pie chart illustrating that most passengers from Scaroborugh go to either Leeds or York with a mere 2% travelling to Manchester.
Of course, these ideas are still in the planning stage and nothing is concrete yet as far as I can gather.
