Industrial action means there will be a very limited train service today.
Train operator GWR is advising only travel by rail if necessary. If you do travel, expect severe disruption and plan ahead.
Services will will only operate between 7.30am and 6.30pm on Saturday and there will be a knock-on effect on Sunday.
On Saturday the operator is aiming to provide about 30 per cent of its usual timetabled services, and about 50 per cent on Sunday.
However, they hope to provide full services again from Monday June 27.
GWR Managing Director Mark Hopwood said: “We recognise that this week has been difficult for those who need to travel. We’ve been doing our best to provide scheduled services on key routes, which is hopefully making a difference.
“Services are however starting and finishing earlier throughout the strike period with an extremely limited service operating this Saturday between 0730 and 1830.
"On Sunday, no services are running before 0700, and we will also be working hard to re-position our fleet for Monday’s return to normal.”
Where trains are able to run, they are expected to be extremely busy and replacement bus services are not able to be provided.
Today is the final strike day by the RMT union against train operators and Network Rail.
