On Sunday a service train was on the Northbound platform at Colindale.
It looked quite different from the usual trains, and there were
computers, desks and things like that inside - plus a guy who looked
fairly busy.

I know the NL was messed up on Saturday, but I've never seen a mobile
office of this kind before. Someone here must know all about them,
though!

Track recording train?

Depends. The Track Recording Train was stabled in Highgate Depot on Sunday
afternoon, however if the sighting was morning or evening then it would be
very likely to be the TRT on the basis that it was on the Northern Line on
that day.

Record the state of the track?

Basically, there are lasers and cameras and alike that can check the track
for internal cracking.

That figures, as it was in Highgate at about 1430-1500.

See reply from Mr. Mayes!
