Anyway, the point of the line is to cut as much as possible off the
journey
time between London and Paris / Brussels. Running trains at 186mph is the
plan - your commuter trains at 140mph would get in the way.

Half the CTRL-DS trains will turn off at Ebbsfleet, and AIUI the line limit
between St Pancras and Ebbsfleet will be 140 mph or less. Between Ebbsfleet
and Ashford the peak demand for the forseeable future will be 4 tph for E*
and 4 tph for CTRL-DS, and the line will be perfectly capable of
accommodating these, even with a 186/140 mph speed mix.

Good point - especially valid if they run the Eurostars in pairs, one
to Brussels and one to Paris.

I also think St Pancras to Ebbsfleet is mostly tunnel, where the
trains are speed limited by the design of the tunnel.

So why is this an issue? Why the delay?
