Background information:

Since early 2022, Network Rail have 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 between Saturday 25 October and Sunday 2 November, during the autumn half-term.

The main focus of this final phase is the commissioning of the Farncombe to Petersfield resignalling scheme. 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. More information on this project is available from the Network Rail website.
