Rail passengers are being warned of delays and cancellations on services running between London Paddington and Slough this morning.
A signalling fault between Slough and West Drayton means some lines are blocked.
Operator Great Western Railway said services running to and from Slough and Paddington may be cancelled, delayed by up to 30 minutes or revised.
Disruption is expected to continue until 1pm.
More than 50 street parties are set to take place this weekend across the Royal Borough of Windsor and Maidenhead and the surrounding areas.
