We’re upgrading signalling and track on the Portsmouth Direct line to improve reliability and safety of services between London and Portsmouth

Since early 2022, we’ve been delivering a major programme of upgrades on the Portsmouth Direct line. These improvements have been delivered in phases and are designed to provide a safer and more reliable service for everyone travelling on this route.

We’re now entering the final phase of this programme. To complete the work, rail services will be replaced by buses between Saturday 25 October and Sunday 2 November 2025, during the autumn half-term.

What work is taking place and why?

The main focus of this final phase is the commissioning of the Farncombe to Petersfield (F2P) resignalling scheme. There will also be upgrades to nine level crossings and two footpaths.

As part of our work signalling control will be transferred to the Basingstoke Railway Operating Centre (ROC) and the 90 new signals and 17 new signalling equipment buildings that have been installed and constructed, will be tested during the line closure. Transferring to the ROC WILL enable faster and more efficient train management.

Between September and November, we’ll be upgrading nine level crossings to make them safer for all road users. We’re replacing manual level crossing operations with new technology including Obstacle Detection (OD) and CCTV control. These upgrades will result in slightly longer barrier downtimes but will significantly reduce the risk of accidents and injuries for pedestrians and drivers.

When is the work taking place?

The line between Guildford and Havant will be closed for signalling work from Saturday 25 October to Sunday 2 November 2025.

We will replace manual level crossing operations with new technology including Obstacle Level crossings with the closures as scheduled below:

  • Liss Common Level Crossing Closure: Saturday 27 September – Friday 24 October 2025
  • Kings Fernsden Level Crossing Closure: Saturday 4 – Friday 24 October 2025
  • Princes Bridge Level Crossing Closure: Saturday 11 October – Saturday 25 October 2025

  • Liss Level Crossing Closure: Sunday 26 October – Monday 3 November 2025

  • Farncombe East Level Crossing Closure: Saturday 25 October – Sunday 2 November 2025 (nights only)
  • Farncombe West Level Crossing Closure: Saturday 25 October – Friday 14 November 2025

How will this work impact me and how will we be informed?

We’re committed to keeping passengers, residents and road users informed throughout our works. Updates will be regularly posted on this webpage.

Lineside neighbours closest to the works will receive letters in advance with full details of activity and any likely impacts. While some noise and disruption is expected, we will work hard to minimise this wherever possible.
