Planned engineering works will affect some Thameslink services over the weekend – here’s everything you need to know.

On Sunday there will be a number of timetable changes and service alterations as engineering works are set to take place over the weekend.

Some early morning services will be altered or will not run whilst engineering works take place and some services will not serve certain stations.

A replacement bus service will run for some services affected and customers are being advised to use alternative services with their Thameslink tickets to complete their travel.

Here’s everything you need to know:

Saturday, August 5

On Saturday there are currently no planned works scheduled to take place and so a normal service is expected to run on this day.

Sunday, August 6

An amended service between Slade Green/Sidcup and Gravesend will be running on Sunday.

Trains on this line will run once every hour between Kentish Town and Plumstead.

Two trains will also run every hour between Gravesend and Rainham.

Thameslink customers are being advised that tickets will be accepted on Southeastern services between Plumstead and Slade Green, or on Southeastern replacement bus services between Slade Green and Gravesend.

Between 6.46am and 7.16am planned engineering works taking place between Orpington and Bromley South will close the line before 9am.

Customers traveling from Orpington to London Blackfriars on the 6:46 or the 7:16 service will need to travel to Bromley South via a rail replacement bus service, and travel from Bromley South where the service starts.

There will be no Thameslink service running between London Victoria and Sevenoaks whilst engineering works take place.

Engineering work taking place between London Victoria and Loughborough Junction will close some lines until 10am on Sunday.

Trains that usually run between London Victoria and Sevenoaks will be diverted to start and terminate at London Blackfriars.

The 8:30am and 9am services between London Bridge and Sutton will start from London Friars instead of London Bridge whilst engineering work takes place between London Bridge and Tulse Hill.
