Prototype 4-Bogie Nuclear Flask Wagon - Suspension Cleaning
During the testing of new wagons, poor riding or instability was often caused by insufficient damping in the suspension; this could be attributed to contamination of the friction damper surfaces, which meant that the bogie or suspension had to be dismantled to clean and de-grease before a retest was carried out.
The Y25 cast frame 1.8m bogie of a 4 bogie Nuclear flask wagon being attended to at the EDU workshop in the RTC Derby in 1989.
