Thousands of rail workers and train drivers are going on strike this month – with an overtime ban which started on Monday and mass disruption expected today.

But planned industrial action by London Underground workers has been cancelled, it was announced on Tuesday.

RMT (the Rail, Maritime and Transport union) and ASLEF (The Associated Society of Locomotive Engineers and Firemen) members are striking in an ongoing dispute over pay and conditions.

ASLEF represents drivers, whereas the RMT represents workers from many different sectors of the rail industry – including station staff and guards.

Here is everything you need to know about which services are affected this week.

London Underground

Tube workers had been planning to walk out on Wednesday 4 October and Friday 6 October.

The industrial action would have “severely affected” most underground lines and there would have been no night tube on 6 October, either.

But on Tuesday unions announced the planned strikes have been called off.

Around 3,000 members of the Rail, Maritime and Transport union (RMT) had been due to walk out during the two days of strikes.

The RMT said that following talks at the conciliation service Acas it has managed to save jobs, prevent detrimental changes to rosters and secure protection of earnings around grading changes.

The union said: “The significant progress means that key elements have been settled although there remains wider negotiations to be had in the job, pensions and working agreements dispute.”

RMT general secretary Mick Lynch said: “I congratulate all our members who were prepared to take strike action and our negotiations team for securing this victory in our Tube dispute.

“Without the unity and industrial power of our members, there is no way we would have been able to make the progress we have.”

Avanti West Coast

Avanti West Coast will not be operating any services on Wednesday 4 October.

Customers who booked tickets to travel on these days can claim a full, fee-free refund from their point of purchase.

Customers with pre-booked tickets for travel on a strike day can use their ticket the day before or the two days after.

Avanti plans to run its normal timetable during overtime bans, but recommends you check before you travel as the impact will vary from route to route.

C2C

There will be no C2C service on Wednesday 4 October.

On days when overtime bans are in place, there will be a reduced peak time service and a reduced frequency of two trains per hour during off-peak hours across all routes.

First and last trains will be unaffected.

Chiltern Railways

There will be no Chiltern Railways services on Wednesday 4 October on any routes.

Although industrial action on the London Underground has been suspended, there will be impacts on Chiltern Railways services at the London end of the route.

On 5 and 6 October no services will be calling at stations including; Harrow-on-the-Hill, Rickmansworth, Chorleywood, Chalfont & Latimer and Amersham. This is until after 8am on Thursday and all day on Friday.

On Saturday 7 October, no Chiltern Railways services will call at South Ruislip until after 8am.

GTR

GTR, also known as Govia Thameslink Railway, is the UK’s biggest railway franchise and operates Southern, Thameslink, Great Northern and Gatwick Express.

On days when an overtime ban is in place, GTR says an amended timetable with fewer services will run.
