Description

A fault with the signalling system between London Paddington and Reading means some lines are blocked. Trains running between these stations may be delayed by up to 20 minutes or cancelled.

Disruption is expected until 15:00.

Great Western Railway customer advice:

Local stopping services between London Paddington and Didcot Parkway / Newbury will only run between Reading and Didcot Parkway / Newbury. Most longer distance Intercity services will continue to run between London Paddington and Reading, but may be subject to delay.

If your train is cancelled, you may travel on either of the two services before, or two services after, your original train. If these are peak services or less flexible, you can still travel with your original ticket, at no extra cost.

Check before you travel:

You can check your journey using the National Rail Enquiries 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.
