RMT rail staff are taking industrial action this weekend leading to Thameslink cancelations and timetable chances – here’s everything you need to know.

Today (July 29), RMT union rail workers will be taking industrial action leading to a number of timetable alterations and cancelations.

Services are expected to start later on Sunday (July 30) following the industrial action of the day before.

Customers are being advised to check before they travel, with stations and services anticipated to be busier than usual.

Thameslink customers are also being advised they may have to queue, with some possibly not being able to board trains if overly busy.

Here’s everything you need to know:

Saturday, July 29

On Saturday there will be an amended timetable with fewer services running.

There will be no cross-London Thameslink services running between London St Pancras and London Bridge on the day.

For passengers traveling south of London routes to and from Oxted to Uckfield, Eastbourne to Ore and Kent services to and from Rainham and Sevenoaks will be open from 7am until 7pm on Saturday.

Anyone traveling with Thameslink to the north of London should plan their journey and check train times as services are expected to start later and finish earlier than usual.

Customers are advised to plan ahead and check before they travel, with some stations expected to be busier than normal.

Customers traveling to and from Gatwick Airport can still travel using Thameslink and Southern trains, however the non-stop Gatwick Express service will not be running on July 29.

Sunday, July 30

On Sunday services are expected to start late following the previous strike day.

However, the timetable is expected to return to a normal Sunday service following the later start.

Chris Fowler, Head of Network Operations for Govia Thameslink Railway, said: “We’re really sorry about the impact that this round of industrial action is having on our customers, especially as many will be looking to start their summer holidays.

“We’re running as many trains as we can, but unfortunately on most routes there will be some times where people will be left without a service.

“It’s incredibly important that people check their journey before they travel and leave plenty of time, as trains will be much busier, particularly where services are starting later and finishing earlier than usual.”
