Nine day closure affecting all trains via Horsham from Saturday 14 August to Sunday 22 August 2021 (inclusive)
Passengers are advised to plan ahead for major work on the Arun Valley Line in summer. Network Rail engineers will be rebuilding a crucial section of West Sussex’s railway, including a nine-day period in August when there will be no trains at all through Horsham, plus five weekends of engineering closures in July, September and October.
From Saturday 14 to Sunday 22 August 2021, buses will replace trains along much of the Arun Valley line, from Arundel to Three Bridges including Horsham and Crawley, and the Mole Valley line between Horsham and Dorking.
Additionally, there will three weekends of engineering closures ahead of the main work and these will take place on Sunday 11 July, Saturday 17 to Sunday 18 July, Saturday 31 July to Sunday 1 August 2021. Following the main closure, there will be a further two weekend closures on Saturday 4 September to Sunday 5 September and Sunday 3 October.
Network Rail engineers will use the time to invest £8.5m to replace 1980s track and infrastructure, with new, more reliable equipment.
Arun Valley Line improvement project survey
We are asking passengers to take a few minutes to complete this short survey on the renewal project and line closure on the Arun Valley Line.
What the work will involve and where
- The complete renewal of 9 sets of old switches and crossings, the movable sections of track that guide trains from one track to another and allow them to cross paths. The existing equipment has been in place since the 1980s, is old and unreliable and needs to be replaced. The new, more reliable equipment will reduce faults and delays to passengers.
- A section of rail, sleepers and ballast will be renewed at Horsham station, and track drainage improved to help reduce or prevent the risk of flooding on the line. The upgraded track will give passengers smoother, more reliable journeys and maintain track quality for the long-term.
- Enabling work for the upgrade of Parsonage Road level crossing to a full barrier CCTV crossing to improve safety, and recontrol of Littlehaven signal box to the Three Bridges Rail Operating Centre (ROC) in June 2022.
- To give passengers additional benefits Network Rail and train operators are looking at options to refurbish stations when they are closed.
Better, more reliable journeys – Arun Valley services are amongst the worst performing in the region, experiencing more delay than the average train service in the area. These essential renewals and upgrades to the Arun Valley Line infrastructure will help modernise the network, allow for future passenger growth, and improve passenger journeys.
Reduced risk of flooding on the line – Drainage improvements will also help reduce or prevent the risk of flooding on the line.
Less overall disruption to passengers and the benefits delivered sooner – This investment was originally planned for several bank holiday closures, supported by a long series of weekend possessions over two to three years. By doing the work over nine consecutive days and two weekends, the overall disruption to passengers can be significantly reduced, while fast-tracking the delivery of the reliability, safety and connectivity benefits of the project.
- Enabling work: Sunday 11 July, Saturday 17 – Sunday 18 July and Saturday 31 July – Sunday 1 August 2021 – Weekend closures affecting all trains via Horsham.
- Nine-day closure: Saturday 14 August – Sunday 22 August (inclusive) – Nine-day closure affecting all trains via Horsham.
- Follow-up work: Saturday 4 September – Sunday 5 September and Sunday 3 October – Weekend closures affecting all trains via Horsham.
Map of key affected routes
The work requires all lines via Horsham to be closed. Crawley station will remain open on weekdays during the nine-day period but closed on all affected weekends.
Services on longer distance coastal journeys to Chichester, Littlehampton, Bognor Regis and Portsmouth will still be running, but will go via an alternative route using the Brighton Main Line, meaning journeys will take longer.
The closures have been planned for summer, when some people may be more flexible with their travel plans. We’ll ensure that alternative routes are fully open on these dates, and we’ve timed the work to avoid Brighton Pride.
Passengers wishing to travel along the Arun Valley line on these dates will need to allow considerably more time for their journeys and should expect to use either diverted trains via longer routes or a replacement bus or coach to connect with rail services.
We are working to ensure people have as many alternative options as possible over the closures and will confirm detailed travel arrangements next year.
