Services between London Victoria and Horsham will be affected from Monday, January 5 to Thursday, January 8, with works scheduled to take place between Three Bridges and Horsham.
A key service impacted is the 11.35pm London Victoria to Horsham train, which will terminate early at Three Bridges instead of completing its usual route.
A rail replacement bus will operate for passengers needing to travel beyond Three Bridges, departing at 12.46am and serving stations onward to Horsham.
A spokesperson said: “Please be advised that replacement vehicles may be busier than usual, and you should allow extra time for your journey.”
Passengers can check journey plans and rail replacement service details on the National Rail Enquiries website.
Further advice on accessibility and bicycle policies for replacement buses is available on the National Rail Rail Replacement Services page.
Pick-up and drop-off locations for the replacement service are displayed at stations and can also be found online via the National Rail Find a Station tool.
