I didn't get a very good look at what went through Chippenham around 1030 this morning. Four or five yellow coaches topped and tailed by what sounded like a couple of class 66 locomotives (but that last bit is little more than guesswork!)

What was it?

Network Rail have a number of these trains, the true flying banana is officially known as the NMT 'New' Measurement Train (although I think new has been changed to National) this is 2 class 43 and a rack of Mk3 (basically an HST (High Speed Train)); the train has a whole range of geometry, gauging, ride quality instruments, there is another train called Mentor which is OLE (Overhead Line Equipment, more often "OHLE") specific, telcoms have one for GSMR, plus a there a small track recording trains for lesser lines.

Resurrecting an older thread rather than starting a new one because the subject is so similar.

Quote
Light Detection & Ranging and imagery capture technology will be installed on passenger trains operated by Great Western Railways. This will allow for real-time track monitoring of Network Rail's infrastructure, reducing the need for special measurement trains.

Here's the full quote from an investment news service.
Quote
Cordel Group PLC, up 27% at 6.69 pence, 12-month range 4.00p-16.25p. The transport-focused artificial intelligence firm wins a five-year contract with London-based stock rolling firm Angel Trains for the installation of automated hardware on passenger trains. Cordel's Light Detection & Ranging and imagery capture technology will be installed on passenger trains operated by Great Western Railways. This will allow for real-time track monitoring of Network Rail's infrastructure, reducing the need for special measurement trains.

I guess the cost of the technology has been gradually coming down thus making it economic to deploy on more trains, just as video recording now seems to have become ubiquitous on anything that moves.

That story has, perhaps, more to do with this thread - being about fitting LIDAR or other monitors equipment to passenger trains. There was also a news item about Northern Trains doing much the same, though it didn't mention who was providing the equipment/service.

But in both cases the obvious reaction is the same - it's not their (Angel or Northern) track, is it? presumably Network Rail are involved in this in some way, in which case it's odd that they are keeping out of sight. They were involved with Fugro in that earlier trial, and Cordel have got NR» (Network Rail - home page)'s logo on the web site ...

The Southern Regions' Kent Route has been trailing thermal imaging camera fitted in a class 707 to look for 'hot lugs', 'hot joints' and failing 'pots' especially ceramic ones on the third rail.  The Region is looking to trial the camera in class 377's
