Here is our weekly travel update to help you get around London this weekend, 21-22 April, and also the following week. Most of the network will be open with services running as normal, but please check if any of the following affect you.

Strike action is taking place on the DLR from 04:00 on Friday 20 April, until 03:59 on Tuesday 24 April. The strike has been called over a dispute with KeolisAmey Docklands who operate the DLR on behalf of TfL.

We aim to offer a limited service over the four days, which coincide with the London Marathon on Sunday 22 April. For up to date information on what services may operate.
