In the last day London has experienced flooding as part of the consequences of the most recent storm to grip the UK.
As a consequence many train lines are flooded in and around London, including the HS1 Eurostar and Javelin high speed line between the coast and London, including the HS1 line under the Thames (rain, not river, water).
All services on Eurostar in the UK are cancelled (and were last night) until at least tomorrow.
At 7:37 GMT 31 Dec 23 this morning one of the two tunnels on the HS1 line under the Thames near Ebbsfleet has reopened allowing some trains to run on the Eurostar and Javelin services.
Engineers are still working on the second tunnel which still has water in it.
Check before you travel
Mid morning update - water is now out of both tunnels and trains are running, some Javelins turning short. Eurostar are predicting delays and more people than seats into midweek.
