Description

A safety inspection of the track between Wimbledon and Sutton means that trains have to run at a reduced speed on the line towards Sutton. As a result, trains running between these stations may be delayed by up to 10 minutes.

This is expected until 16:45.

Customer advice:

Can you tell me more about the incident?

Network Rail is carrying out a safety inspection of the track between Wimbledon Chase and St Helier following a report of a possible problem in the area.

When a possible fault is reported or detected by track-monitoring equipment, railway safety rules require train drivers to reduce their speed through the affected area until the track has been inspected. This allows trains to continue running safely while specialist teams investigate.

Because trains are travelling at slower speeds, they may begin to queue behind one another. In severe cases, some services may need to be cancelled or revised to prevent delays from building up across the wider network.

Once the safety inspection has been completed, Network Rail will decide whether any further work is needed or if it's safe for trains to run at normal speeds.

Ticket flexibility:

If your train is cancelled, you will be able to travel on an alternative service operated by any other participating train company, either two hours before or two hours after the original departure time of the cancelled service, in order to reach your destination.

If you decide not to travel or cannot complete your journey due to cancellations, you are entitled to a full refund from your original point of sale.

For further information and guidance please contact your train company or speak to a member of railway staff.

Check before you travel:

You can check your journey using the National Rail real-time Journey Planner.

Compensation:

You may be entitled to compensation if you experience a delay in completing your journey today. Please keep your train ticket and make a note of your journey, as both will be required to support any claim.
