Service alerts

This page is updated regularly when we have advanced notice of issues which may cause changes to our scheduled timetable.

  • Friday, 10 October 2019

Due to the current delays on the Jubilee line we will run a River Bus shuttle service between Canary Wharf Pier and London Bridge City Pier (charged at our standard pricing) between 17:00 and approximately 19:30 (first and last departure from Canary Wharf Pier).

To help us optimise capacity during the commuter peak, customers are kindly requested to leave extra time for their journeys.

If severe delays on the Jubilee line persist after 22:00 we will run a River Bus shuttle service until midnight between North Greenwich and Greenwich piers.

What causes service delays and alerts?

Spontaneous service delays can be caused by a number of issues including river congestion, pier congestion, passenger demand, passenger disruption and occasional technical issues with our vessels. When we are aware of these disruptions, a service alert is issued via our Twitter page.

Anticipated service alerts can be caused by:

  • Thames Barrier closures
    The Thames Barrier is located between Woolwich Royal Arsenal and North Greenwich Piers. When the barrier is closed for tests, or to prevent London from flooding, our services are unable to reach Woolwich Royal Arsenal Pier.
  • Riverside activities
    The Thames is an incredibly active river and events regularly take place along its banks and on the river itself which have the potential to affect some services.
  • Tidal conditions
    At extremely low tides, our vessels may be unable to dock successfully at some of our piers or it may be unsafe for passengers to attempt to board from them. Low tide also limits the Thames’s river traffic capacity which can cause congestion.
  • London fog
    In extreme fog our services cannot operate. As foggy conditions can change rapidly, please check our Twitter page for the most up-to-date information.

About our Twitter updates

  • Our fleet control update Twitter with delay information using TfL’s wording for delays. “Minor” refers to delays between 5-15 minutes. “Severe” refers to delays that are over 15 minutes.
  • When a service is “suspended between two piers” this means that the service is not able to run between the piers mentioned or at the intermediate piers.
  • We cannot always give a specific reason for each individual delay nor can our fleet control respond to individual tweets asking about the arrival time of your service.

We apologise for any inconvenience that service disruption has caused to your journey and we always appreciate your patience while we manage the matter.
