PASSENGERS hoping to travel by train to and from Somerset stations this week are being warned to plan ahead due to industrial action.

There will be severe disruption to rail services due to the action by the RMT, Aslef and TSSA unions,

On both strike days (Wednesday, July 27, and Saturday, July 30) an extremely limited service will operate between 7am and 6.30pm.

On non-strike days, no services will run before 7am. Due to the timing of the strike action, services either side of the strike days will also be affected up to and including Sunday (July 31).

Passengers are advised to find alternative ways to travel during the strike period. Only travel if absolutely necessary.

The majority of train services will not operate and there will be no services on some routes.

GWR will operate as many trains as possible during the strike action, however, most train services will be affected on the days announced.

No rail services will operate on Wednesday July 27 on the following routes:

• All lines in Cornwall, including all branch lines;

• Beyond (west of) Exeter towards Plymouth / Cornwall (due to no contingency signallers);

• All branch lines in Devon (Barnstaple, Exmouth, Paignton, Okehampton);

• South Wales main line (Carmarthen/Swansea-Cardiff Central);

• Berks & Hants line (Reading-Taunton via Castle Cary);

• Wessex main line (Bath Spa-Portsmouth Harbour);

• Heart of Wessex line (Westbury-Weymouth);

With train drivers set to strike on Saturday, July 30, GWR expects to operate even fewer services on the second of the two strike days.

On Saturday an extremely limited service will only operate on the routes below. Services will also start later and finish much earlier than normal.

• Bristol Temple Meads-London Paddington;

• Bristol Temple Meads-Cardiff Central;

• Reading to Oxford;

• Reading to Basingstoke.

No other GWR services will run.

Customers who have already purchased tickets can claim a full refund or amend their ticket; those who travel and are delayed may be entitled to delay repay compensation if they are delayed by 15 minutes or more. Season ticket holders can apply for compensation through the Delay Repay scheme.

Where GWR is able to run services, they are expected to be extremely busy. The train operator is not able to provide bus replacement services.

To help customers, GWR is allowing people with tickets for travel on strike days to be able to travel on the day before and up to and including Tuesday, August 2.

GWR is working to update journey planners with the changes to timetables as soon as possible. Online journey checkers are expected to be updated with the latest timetable information as per below:
