A fault with the signalling system between Alton and Farnham means all lines are blocked. As a result, trains may be cancelled, delayed or revised to terminate / start back at Farnham.

Disruption is expected until 21:00.

South Western Railway Customer Advice:

We have been informed that there is a track circuit failure between Farnham and Alton. This means that trains trains are unable to run on these lines.

For further information or onward travel advice please speak to a member of staff or use a station help point.

Further information:

A track circuit is one system used by signallers to identify where trains are on the tracks. When these fail, trains have to stop at each affected signal and verify that the track beyond the signal is clear. Once they have authority from the signaller to continue, they must do so at caution until they have traversed that signalling section. This process takes up to 10 minutes per affected signal.
