Lab 6 'Prometheus'

In 1975 a Mk1 SK coach W34875 was converted into an electrical systems test car at Swindon and was known as Lab Coach 6 RDB975442. It was utilised for main line OHLE tests by the R&DD Electrical Engineers Section and originally based at Rugby but was eventually transferred to RTC Derby.

It was designed such that it could carry a pantograph under 25kV OHLE and was fitted with insulators on the roof and earth brushes on the axles and was initially based at Rugby.

The vehicle was equipped with a conference area and kitchen (below the flat roof area) a large instrumentation area, a generator compartment and a separate  workshop.  It had a vertical internal ladder situated between the kitchen and the instrumentation area which accessed the flat roof. This was via a hatchway which was locked and the key was only available via a safety control procedure for use under 25kV OHLE.

The main instrumentation area has a raised dias from which any pantograph fitted to the flat roof area could be observed. Instrumentation including a large speedometer were also fitted on a facia below the window which was fitted with strengthened glass.

The vehicle was also equipped with Mk3 bogies and was capable of being hauled at up to 125 mile/h

The vehicle has now been scrapped.

Stafford

Test Car 5 (ex-Prometheus) in its Serco livery at Stafford - it was only used as a test car on rare occasions and eventually fell into very poor internal condition. Such a shame as it was originally a 125 mile/h vehicle.

Lab 6 pictured leaving RTC and going for scrap on 21st February 2007.

From the left was the engine room, workshop, instrumentation area with roof window (and wipers still in situ), the roof access compartment (with hatch visible on roof) and then the kitchen/conference area with two seats visible.
