Rail strikes beginning tomorrow are expected to disrupt travel around Buckinghamshire until October 8.

Trade Unions at Great Western Railway (GWR) and Network Rail are among those taking industrial action on Saturday, October 1, Wednesday 5, Thursday 6, Friday 7 and Saturday 8.

On these days train services will be “severely disrupted” and some parts of the GWR network will have no train service at all, according to the train operator.

The strike action will affect travel to this Sunday’s London Marathon.

Delegates travelling to the Conservative Party conference this weekend will be among those affected by the disruption.

On strike days an extremely limited service will operate between 0730 and 1830, first trains will start later, and the last trains will leave much earlier.

Where GWR is able to run services, they are expected to be extremely busy and bus replacement services are not able to be provided.

Online journey planners have been updated with the latest timetable information.

Passengers are advised to find alternative ways to travel on these days. Only travel by train if absolutely necessary, said GWR.
