Curious. The trains are timetabled at only 125MPH, with higher speeds
only used to catch up when running late.

Presumably the speeds in tunnel are lower still?

No, the max speed in the newer section from Southfleet Jn to London is 230
km/h (140 mph). It is Eurostar that is running below normal speed in this
whole section, including the London tunnels...

The proper LGV speeds cease where they used to turn off into South London
