For the third time this week, commuters using Southwestern Railway are facing disruption because of strike action.

There is a reduced service on much of the network this morning (January 12) and even rail replacement buses on the line between Weybridge and Virginia Water.

The disruption is a result of a strike by the RMT Union.

Southwestern Railway said in a statement it expected to run more than 70 per cent of its normal service, including by running longer trains to provide a higher percentage of routes.

Below is the operator's map showing how the strike is affecting routes.
