Here's a long one.....

Hi all,

Just found this on OTT. Presumably used to check the condition of the track on various routes but certainly taking rather a while about it. About 17 hours in fact....!

Damn, that's long. Any idea what it is, looks like a NR test train or a tamper or something like that. I'm guessing they do several crew changes en-route :P
Check out that route map. :P

I suspect it is either an ultrasonic test train or a plain line pattern recognition train, even so, it is a long schedule. It must have crew changes as normally you require 2 x 30 min PNB or 1 x 45 min on a circuit that is half that length.

It's the Bristol-based 'water cannon' RHTT (RailHead Treatment Train),
one of 20 loco-hauled RHTTs which operate each November and December.

(the paths are kept 'in the system' year round to ensure they are
not used for something else in the other ten months!)

Are NR masking class 3 schedules aswell then ? (should have guessed RHTT if I had bothered to look at the date.....)

Which annoys the freight bods intensely as they see them as valid white space outside leaf fall.

Schedules operated by ATOC code ZZ, so even the mail trains, etc. will be masked
