Page 109 Manchester to Sheffield: rationale and alternatives considered
3.89 The Government's commitment on NPR related only to Manchester-Leeds, but the IRP has also considered Manchester-Sheffield links. Currently, the journey between Sheffield, one of the core cities in the Northern Powerhouse and the centre of the South Yorkshire region, and Manchester, takes 50 minutes, despite the cities being 30 miles apart.
3.90 The Government agrees with Transport for the North that any further future improvements to Manchester–Sheffield would best be based on an upgrade and electrification of the existing Hope Valley Line.
The Proposed Portfolio for the North and Midlands
3.91 The Hope Valley route has also been identified as a potential candidate for electrification by the Traction Decarbonisation Network Strategy. Moving heavily loaded freight trains using electric traction would enable journey times to be reduced and make best use of the available network capacity.
Work by Network Rail has shown that – if combined with a connection to the HS2 station at Piccadilly – electrification and upgrade of the existing Hope Valley line between Manchester and Sheffield could give a journey time of between 30 and 35 minutes and support up to four trains per hour (2 via Marple and 2 via Stockport). The scope of interventions that need to be delivered within the Peak District National Park will need careful design to ensure environmental impacts are mitigated and reduced as far as possible.
3.92 The main alternatives that have been considered are:• a new route from Manchester to the HS2 Eastern Leg, capable of serving both Leeds and Sheffield; this has been rejected for the reasons set out in paragraph 2.28 above; and a new alignment focussed on Sheffield to Manchester;this was rejected as likely to have a poor business case and unacceptable impacts on the Peak District National Park.
3.93 Works to improve the Hope Valley line are already underway, including line speed and capacity works, the removal of a bottleneck at Dore, and provision of a freight loop at Bamford. These works could help facilitate a possible future third fast Sheffield to Manchester service each hour.
3.94 Network Rail’s capacity analysis suggests that three NPR trains per hour between Manchester and Sheffield can be operated via the Hope Valley Line with trains continuing to Stockport through targeted investment, using the existing Network Rail station at Manchester Piccadilly.
This would likely require the doubling of the Hazel Grove chord (to enable three trains to be evenly spaced, around every 20 minutes) and restoration of a third line between Dore and Sheffield, although more detailed analysis is needed to confirm this. The infrastructure required onthe Hope Valley route itself is potentially similar if four fast NPR trains are planned. However, operating a fourth train via Stockport into the existing Piccadilly station would require either a major package of interventions on the existing railway or a reduction in other services in the Manchester area.
3.95 The feasibility of a connection from the Hope Valley line to the HS2 station at Manchester Piccadilly has also been explored. This could use a section of the Marple Line, and then join the Leeds approach line to the new Manchester Piccadilly station. Strategically, this would have benefits in terms of faster journey times from Sheffield to Manchester, Manchester Airport, Warrington and Liverpool, and could allow a 4tph fast service between Sheffield and Manchester: two via Stockport and two via the Marple route. This would also mean some long-distance NPR services would not need to use the Castlefield corridor. However, costs for the initial designs of the Marpleconnector appear high, raising challenges in terms of affordability and value for money; and there are potential conflicts with Transport for Greater Manchester’s longer[1]term ambitions to extend Metrolink services onto the Marple line.
3.96 Recent work has suggested there may be potential to significantly reduce the cost of options so far considered.
Any future development work will therefore focus on an upgrade of the Hope Valley route, including capacity and the Proposed Portfolio for the North and Midlands line speed improvements, and route electrification; and an assessment of whether there is a case for moving from three to four trains per hour taking account of demand, costs, and service options at the Manchester end of the corridor. As noted above, the Government has identified a core pipeline of schemes and any further schemes will be subject to affordability, delivering commitments on time and to budget, and complementary investments being made
