From my South Western Railway email alerts here are a selection of recent messages:
On 2/8/22
We have been informed that a road vehicle has struck a bridge between Clandon and London Road (Guildford). Staff are en-route to examine the bridge. In the meantime, trains will remain at stand.
We're sorry but we expect there may be cancellations, delays or alterations to services until 14:00.
On 3/8/22
We have been informed of a safety inspection of the track between Clandon and Guildford. This means that the line towards Guildford is currently blocked.
Until further notice, trains between London Waterloo and Guildford via Cobham will be terminated at/started from Effingham Junction. Trains from London Waterloo to Guildford via Leatherhead will be diverted via Woking.
We have requested rail replacement buses to run between Guildford and Leatherhead and these will be in place from 17:30.
On 8/8/22
We have been informed that a road vehicle has struck a bridge between London Road Guildford and Clandon. Staff are en-route to examine the bridge. In the meantime, trains will be unable to pass between these stations.
On 10/8/22
We have been informed that a road vehicle has struck a bridge between Clandon and Guildford. Staff are en-route to examine the bridge. In the meantime, trains are unable to run over the bridge so may be diverted or delayed.
Ok, so the alert on 3rd August may not relate to a bridge strike but do all the others this month relate to the same bridge? What is happening in this area?
Searching all my emails dating back to 2017 I see no other alerts for a bridge strike in that area.
