Having re-read what Paul has written it looks like the through trains
from Horsham will only stop (I'm guessing here) at Stevenage, Hitchin,
Letchworth, Baldock and Royston.

What's going to serve the various intermediate stations north of
Baldock? Colin's been thinking there's a previous undisclosed 5th train
per hour terminating at Kings Cross.

Shepreth and Foxton are a pain because they have AHB crossings at the
London end so over length trains cannot stop in the down direction.

Foxton's a full barrier (with signal box next door). Shepreth might need
converting, a drop in the ocean compared to all the other Thameslink
upgrades.
