"Commuter times and weekend trains can be quite overcrowded on GWR trains (especially on trains to/from London Paddington), mainly due to the fact they tend to opt for 5-carriage trains instead of 9. I’d recommend booking a seat if travelling at these times to save you battling for one. "

"The Pullman Dining experience really is something everyone should try at least once. You can opt for 2 or 3 course meals prepared by chefs Monday–Friday with produce sourced from regions across GWR’s network. First Class passengers can book 2 weeks in advance (not included in the ticket), and Standard passengers can enquire with staff about availability on the day."

"On event days, the station gets extremely busy, and queue management systems are put in place. The regular routes through the main ticket barriers and subway can be cordoned off, meaning passengers may need to follow temporary one-way systems to move around the station or reach platform 1. Allow extra time and check local station staff directions on the day."
