A Derby Lightweight DMBS inside Norwich erecting shop circa 1971. The caption states it's a 'scrap car' so it's perhaps undergoing component recovery. Tim Stubbs.
circa March 1971
The equipment operation control position on DB975008, part of the ultrasonic test train, circa March 1971. The operator can monitor the signals being recorded on film and the operation of the camera, and adjust the positions of the ultrasonic probes which he can observe through transparent panels in the floor.

The floor at the control desk area on Derby Lightweight Ultrasonic Test Train vehicle 975008. It shows two flaps opened up to show access to equipment and the floor windows which allow observation of the probe trolley. Image courtesy of Philip C Johnson. British Railways Board.
circa March 1971
The 35mm photographic recording unit inside 975008, part of the Derby Lightweight Ultrasonic Test Train. These recorded the results from the probes, the analysis of the film afterwards was a slow manual process restricting operation to about 2,000 miles a year. They were later replaced with magnetic tape, the digital analysis was much faster allowing yearly mileage to be increased to about 10,000 miles a year. Image courtesy of Philip C Johnson. British Railways Board.

An official image showing British Railways new two-vehicle ultrasonic rail testing train at work. The power car DB975007 is leading, the trolley carrying the ultrasonic probes is mounted underneath the trailer car (DB975008). Taken circa March 1971, the vehicles were formerly M79018 and M79612 based in the West Cumberland area. British Railways Board.
circa March 1971
An official image showing the trolley under ultrasonic test car DB975008 (ex-79612). This carried the ultrasonic probe heads, these could be lifted to pass over points and crossings, the whole trolley would be raised clear of the rails to allow running at normal traffic speeds. British Railways Board.
circa March 1971
An official image showing the cab of one of the vehicles (975007 or 975008) of the ultrasonic test train circa March 1971. The extra raised seat in the centre of the cab was for the logger who would use the keyboard on the console to note the sighting of lineside mileposts which would record then on the film produced by the ultrasonic test gear. A third seat, out of view, was fro the train captain. Note the traditional Yellow Diamond 'cowhorn' throttle and the matching early style gear controlled has been replaced by the later style controls used on Blue Square vehicles. British Railways Board.

An official image showing the cab of one of the vehicles (975007 or 975008) of the ultrasonic test train circa March 1971. The crew are sitting in position, probably just posing for the photograph, the driver to the left and the logger on the right. Out of sight to the right is another seat position for the train captain. British Railways Board.
circa March 1971
An official image showing the equipment operation control position on DB975008, part of the ultrasonic test train, circa March 1971. Although they can be barely seen in the poor quality image, there are floor windows on either side of the sliding seats. The operator could monitor the operation of the trolley underneath and its ultrasonic probes, the signals being produced and the recording camera function. British Railways Board.

Spring 1971
All of the original West Cumberland trailer cars (M79600-12) were scrapped by Arnott Young at various locations other than two which moved to Derby. There one became part of the Ultrasonic test train, the other, M79610 (which was the original partner of the ultrasonic test train power car M79018) was scrapped at Cohens in Kettering in early 1971, where it is pictured. Tony Wilkins.
Spring 1971
M79610 at Cohens in Kettering in early 1971. During it's time at Derby it's had a hole cut in the side (why?) and glass removed, but otherwise looks complete. Grey paint has been applied (covering graffiti or an experiment?) but it's clear its last livery in traffic was plain blue with yellow cab doors and 3" numbers. Tony Wilkins.
