GREAT Western Railway services have experienced disruption across its whole network today due to a shortage of trains.

Customers were warned to expect cancellations and delays after 'more trains than usual' needed repairs at the same time.

Many services are also running with fewer carriages,with engineers attempting to fix as many trains as usual before the evening rush hour.

An earlier points problem between Swindon and Didcot Parkway has now been cleared. 

Passengers are advised to check before travelling.
