Major changes to Streatham's train services from this Saturday

We have just received this notice from Network Rail about changes to train services through Streatham:

Starting this Saturday, 20 December, there are major changes to train services as Network Rail continues to rebuild London Bridge station.

We have been working closely with train operators and Transport for London to communicate these changes to passengers. We would appreciate it if you could encourage your residents to check before they travel by making this information available on your website, in emails and on social media.

From January, longer-term changes mean that some passengers may have to have their train tickets reissued in order to use alternative routes. More details can be found on our Travel Advice webpage.

As a reminder here is a summary of the service changes.
