Rail users in the West are being cautioned about “significant disruption” to train operations this Sunday. Great Western Railway (GWR) indicated that a combination of planned engineering work and uncertainty regarding crew availability will severely impact services. No trains will run between London Paddington and Reading prior to 11.15 GMT, with a reduced schedule operating thereafter connecting London with Bristol, Devon, and Cornwall. GWR confirmed that tickets purchased for Sunday would be honored on Saturday 23 or Monday 25 November. The company also noted that journey planning systems would not display all timetable modifications before Sunday morning due to the complexity involved in updating the schedule. Beginning Sunday morning, rail operations will either commence or terminate at Reading. From Reading, passengers can transfer to services bound for Waterloo station, or take local trains to Slough, and utilize replacement bus services heading to Ealing Broadway for access to the London Underground. Passengers are strongly encouraged to undertake journeys solely if essential. For updates, follow BBC Bristol on Facebook, X and Instagram.
