The last couple of quarterly TfL Investment Programme reports have stated "following an evaluation exercise, we have selected the option for replacing our track recording vehicle, which records and monitors the alignment and condition of the track." Presumably replacing the 1973TS TRV will include replacing the 1960TS motor cars. Any ideas what the future holds? Do we expect a new TRT, or some alternative like fitting equipment to ordinary rolling stock, either temporarily or permanently?

If the weed killing unit was replaced by a couple of flat wagons top and tailed by battery locos, wouldn’t the same apply for the TRV?

At an Acton Depot open day a while back I remember being shown monitoring equipment mounted on conventional passenger stock.

Yes, ATMS has spread to more lines, but cannot fully replace the TRT. Indeed, the measurements taken by the TRT is used towards calibrating ATMS.
The “latest” plan (it regularly changes, and there are often multiple ones floating around) is either to refurbish the actual 1973TS TRV and run it top and tail between battery locomotives (with all the complications that would bring), or to get the lamented Asset Inspection Train running, or to refurbish the TRV pilot motors (the 1960TS) and install the new signalling on them.
Ultimately it’ll come down to whichever is the cheapest.

Funny enough, going though Ruislip depot the other day, the TRV was outside coupled between locos in this formation, loco, trv, dm, dm, loco

What are the different degrees of signalling compatibility with the yellow submarines?

What are the different degrees of signalling compatibility with the yellow submarines? CBTC and EVs don’t (currently) mix. That’s the important bit; the TRT can cope doing other lines in engineering hours. |

Carl S Watson’s photo site says the TRV has received recent attention at Eastleigh.

I wouldn’t read too much into that! The pilot motors have been back and forth several times over the last couple of years, and most recently the TRV itself. This has mainly been life extension works to keep it running whilst a final decision is made in the future track recording strategy on the network.

There is a medium term project to fit new recording equipment to new wagons and have them hauled by appropriately signalled Battery Locos.
Short term the TRV carries on, but as the railway is re-signalled this becomes increasingly difficult/impossible.
The 1960 Cravens have had a lot of work done to them recently to extend their life but investment has not been forthcoming to fit new signalling, therefore the difficult bit is bridging the gap between now and when the new wagons enter service. Consists involving Battery Locos and the TRV have recently been trialled and works to enable this solution are currently being developed.
