The IEP can solve the white space issue on the ECML fast tracks (ie the
ex Cambridge Cruisers), but there's also the stoppers - who can live in
their own space on the slow tracks and flow through Thameslink rather
than terminating at Kings Cross.

Except that there are no slow lines for a few miles north of Welwyn.

There are a certain number of paths through Welwyn, increasing the top
speed of 2tph from 100mph to 125mph isn't going to change that. What's
the track speed there, anyway?
