Looking at the timetable it appears that the Ely starters at xx:58
don't join at Cambridge (at xy:15), so no 365 units needing to stable
there for a while.
Whereas the Kings Lynn trains arrive Cambridge at xx:41 and spend
six minutes coupling to the spare half of the xx:30 arrival from
Kings Cross (before departing south at xx:47.
While there's a certain diagramming elegance to this, it means that
Ely passengers don't get 2tph "new trains" as promised.

Misters Rosenstiel and Perry, do you even know what group you are in? I
know a bit of off-topic stuff is inevitable and even welcome, but you
two are repeat offenders.

Like it or not, at the very least Cambridge North on what will soon
become Thameslink is a London train service.
