A high priority recommendation is for NR to seek derogation or other technical solution to resolve the sub-standard overlap problems affecting trains travelling into and out of Platforms 20 to 24 at London Waterloo
Sir Michael Holden is pleased that Network Rail has begun tackling this issue; the design phase is now complete, and work is likely to begin in early 2020.
This recommendation remains open.
In the short-term, SWR and NR should carry out a joint operability review ahead of Class 701 operation to identify any infrastructure changes that would be beneficial to performance before their introduction. This would also assist with improving the operability of the existing 10-car railway
Two joint SWR – Network Rail workshops were conducted ahead of the Class 701 trains entering service to determine any infrastructure changes that would be beneficial to its performance.
Several key actions were identified and allocated to the joint SWR and Network Rail Steering Group meeting that governs the Class 701 introduction, the associated timetable change and the Feltham Depot project. The Steering Group, including executive members from both Network Rail and SWR, meet every four weeks and are responsible for ensuring the safe and timely introduction of the new trains for passenger service and removal of the old trains from the network.
In addition – as noted in the response to Recommendation 8 (above) – since completing this recommendation, SWR has also introduced a ‘visualisation’ process, with weekly meetings attend by senior management from each organisation.
A top priority medium term action is for NR to carry out a feasibility study into increasing the Permanent Speed Restriction on the Main Suburban lines into and out of the station, and into and out of Platforms 20 to 24, from 15mph to 20mph
Network Rail has looked to increase the Permanent Speed Restrictions on suburban lines at London Waterloo station by ordering a new, harder wearing switch rail.
Longer-term actions recommended for NR also include:
Improvements to the switch rail will reduce the risk of one of the most common infrastructure failures at Waterloo. A trial of this new material is taking place at Eastleigh and will be monitored over the coming months.
✓ Sir Michael is satisfied that this can now be managed through normal BAU maintenance and the recommendation can be closed.
Considering the provision of closing up signals both the Up and Down Main Slow line platforms at Wimbledon, Earlsfield, Clapham Junction and Vauxhall;
Sir Michael has agreed that this recommendation can be closed following exhaustive feasibility studies which showed the work to be extremely complex meaning the consequential business case could not be justified.
Including the movement of the crossover at Kingston to permit extension of its bay platform to 10 cars in the core scope of the Feltham Area Resignalling project making a longer term significant operability improvement;
The South West Main Line is one of the busiest and most congested routes in the country and faces capacity constraints from rail services going into and out of Waterloo station.
Crossrail 2 would help alleviate this pressure bypassing the most congested stations in London. Several feasibility studies have been conducted as part of the Crossrail 2 development but a review of possible solutions did not identify any benefit to bringing any Crossrail 2 options forward.
This recommendation remains open with a further review of the requirement in early 2020.
Considering motorising and remotely controlling the ground frame controlled trailing crossover between Raynes Park and Motspur Park and creating a signalled route to turnback from the Up Branch platform at Raynes Park;
Network Rail will fund several minor enhancements to core renewal projects that provide similar benefits ahead of full resignalling in Control Period 7 (2024-2029).
✓ This recommendation has been achieved and is now closed.
Consider developing a package of infrastructure enhancement schemes designed primarily to improve the core resilience of the existing timetable structure
Sir Michael Holden recognises this is an ongoing, long-term recommendation which includes enhancements at Twickenham, Bracknell and Virginia Water as part of the Feltham signalling project.
Network Rail and SWR continue to identity minor enhancements as part of business as usual processes in Network Rail Projects and through JPIC.
