The vehicle is mentioned in the following images:

DMU

Date: circa 1970

The cab of one of the vehicles (975007 or 975008) on the Derby Lightweight Ultrasonic Test Train showing the loggers seat and panel. If you look carefully you should see a fine vertical rod attached to and set in from the outer edge of the drivers window. There was one on each side for the logger to line up this with the mile posts as they were passed. This was recorded on the film to give the film examiner a method to precisely locate the location of any defects detected. The driver had a similar set up in front of him to activate a trolley axle locking system when passing through crossovers or S&C. This was necessary as the axles of the trolley were spring loaded outwards to ensure the flanges were always pressed against the gauge corner. Philip C Johnson.

DMU

Date: 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 Note the traditional Yellow Diamond 'cowhorn' throttle and the matching early style gear controlled has been replaced by the later style controls used on Blue Square vehicles.

From the kitchen window of my then nearby home on a date I can't find in my notebooks, but probably in 1985, I saw 31426 arrive at Stratford-upon-Avon with the Derby Lightweight Ultrasonic Test Train (TDB975007/8) in tow. It went into the Down Goods Loop where the class 31 was detached, ran along the up main line to the crossover before being coupled to 6Z08 and prepared to leave. Here, the second man watches the locomotive approach along the by then rarely used loop which was taken out of use within a few weeks. Peter Tandy.

DMU

Date: circa 1985

From the kitchen window of my then nearby home on a date I can't find in my notebooks, but probably in 1985, I saw 31 426 arrive at Stratford-upon-Avon with the Derby Lightweight Ultrasonic Test Train (TDB975007/975008) in tow. It went into the Down Goods Loop where the class 31 was detached, ran along the up main line to the crossover before being coupled to 6Z08 and prepared to leave. After a brake test carried out I took this picture as 6Z08 left the loop to use the crossover (which the signalman maintained wasn't fit to use!) and joined the up main line towards Bearley Junction. Peter Tandy.
