Yes if it is modelled on a semi-fast basis I can see that.
Let’s for a moment assume only the western HS2 branch is built in full. That would mean a Leeds & Doncaster/York XC service would be valuable still. On the Manchester leg, HS2 will take the demand for Manchester & Stockport to Birmingham and the majority of demand for Manchester & Stockport to Reading and Bristol. That then leaves what to do with Macclesfield, Stoke, Stafford & Wolverhampton.
Today these towns see:
- All see 2 tph XC between Birmingham & Manchester
- Stoke has 2 Avanti between Manchester & London
- Stafford has 1 Avanti between Liverpool & London
- Wolverhampton has 1 Avanti between Scotland & London
- Macclesfield has 1 Avanti between Manchester & London
In addition Stafford has 3 semi-fast LNW to Birmingham and 1 semi-fast to London, Wolverhampton has 2 semi fast Avanti between Liverpool & Birmingham, while Stoke has 1 LNW between Birmingham & Crewe.
Post HS2, there will potentially be:
- 1 HS2 London-Stafford-Stoke-Macclesfield (potentially on to Stockport & Manchester)
- 1 ICWC London-Manchester (semi-fast), calling at Stafford, Stoke, Macclesfield & Stockport plus stops on the south WCML.
The HS2 and ICWC provision covers what is needed to London and at best it can be argued that the Birmingham services should, like LNW, be 1 tph semi-fast. In that scenario I would split the two XC paths as:
- 1 tph (semi-fast) Bristol-Manchester calling at:
- Cheltenham, Birmingham, Sandwell & Dudley, Wolverhampton, Stafford, Stoke, Congleton, Macclesfield, Stockport, Manchester
- 1 tph Birmingham-Crewe calling at:
- Smethwick Galton Bridge, Wolverhampton, Penkridge, Stafford, Stone, Stafford, Kidsgrove, Alsager,
- 1 tph Stoke-Manchester caking at:
- Kidsgrove, Congleton, Macclesfield, Addlington, Poynton, Bramhall, Cheadle Hulme, Stockport, Manchester
This then improves commuter services in to Birmingham & Manchester as well as keeping connectivity with Stafford & Wolverhampton and Bristol etc. I’d also be tempted to extend the Birmingham-Crewe slow service to Manchester via Wilmslow, calling at Sandbach, Holmes Chapel, Goostrey, Alderley Edge, Wilmslow, Handforth, Cheadle Hulme & Stockport.
Not if you just do one change at Moor Street or New Street from HS2.
