The TRV (Its correct name is Track Recording Vehicle but is commonly called the Track Recording Train even on timetables!) records the entire Underground network every 8 weeks (with the exception of the Waterloo and City) and does so either via an STN (Special Trains Notice) or the EWSA (Engineering Works and Special Arrangements) publications.
To enable the TRV to record the Chesham branch the above alteration is made. Previously when the shuttle was in operation one round trip would be cancelled.

Thanks Dave, so the three cars should be known as the TRV. I thought only the converted 1973 stock car was the TRV and the 1960s cars were pilot motors.

The middle car is the TRC (Track Recording Coach).
BTW, I'm on it Tuesday (one of the engineers in the TRC)

The Met is the most complicated for us with regard to different routes, roads, crossovers etc but it is one of the easiest when it comes to liaising with controllers and signallers to get those routes. It takes Three days to cover the whole of the Met

dagdave when out on a "run" as such, how often do you find defects with the track?
Is it on a daily basis or does it vary from line to line?
And what exactly does the TRV do - I understand it records the condition of the track but what does it look for?
Thanks in advance bud!

It takes Three days to cover the whole of the Met Hypothetically, if the whole Met was to be done over 3 consecutive days: a) How many hours would the train be out per day? b) How much track could be covered per day? |

Mikeyr1234 and Sean B, I would not expect any defects requiring immediate action, these are extremely rare now with all the track renewals over recent years. There will be a handful of faults requiring track inspection within 24 hours and hundreds / thousands of other measurements indicating the overall track quality.
Parameters measured include 2m Twist, 10m Twist, Cant, Alignment, left and right Tops and Gauge.
We run at line speed so can cover many miles in a day, normally off peak between 10:00 and 15:30 ish
Thanks MetControl, coming over to Neasden tomorrow afternoon.

Interesting mate and many thanks for the response Do you work nights too or is it just normal operating hours? |

We work mostly days during traffic hours except for the Victoria and Jubilee due to the TRV not being fitted with the necessary signalling equipment. We run as the sole train on those lines once all the others have stabled to an Operational Safety Plan.

And don't forget your main people - the Picc and District signalmen!
I've spoken to the TRV the past two days, yesterday as my colleague couldn't give you a Train Description (pressed Circle and Hounslow came up!) and today to see where you were going as you were a tad early ;-)

Yes, I was on board both days Harry. We rely on the Picc and District to get us out and about most of the time. Especially grateful when you let us out on a "Local Arrangement"

Always happy to help of course Unfortunately it went a bit t**s up at a certain location this morning. I won't go into detail anymore but certain locations really must check the fax machine more frequently. No harm done anyway  |
