As mentioned in my email there are a number of alternative rail routes to Berlin.
1. 08.05 Eurostar to brussels Zuid. there is an hour gap then catch the 11.59 ICE to KOLN. then 34min later the ICE to Berlin. I Think it will be the same train.
The return departs Berlin at 09.48 change in KOLN arrice in Brussels 17.01 for the 17.57 Eurostar arriving London 19.05
