Peter Kerslake says "This is the former Metropolitan Vickers Gas Turbine 18100 which following withdrawal from service with British Railways Western Region and an abortive attempt to convert it to use alternative fuel oil was stripped of all its gas turbine power equipment. It ended its days as a crew training locomotive for the forthcoming electrification of the West Coast main line then subsequently as a static test plant for wind effects on the overhead pantograph systems.
Whilst on crew training duties in the early 1960s it was allocated to Longsight. The locomotive was eventually scrapped at Tipton in 1972."

Alistair B Moffat says "This locomotive was also used in Scotland around the time that the Blue Trains were introduced for the North Clyde route "electriification" between Airdrie and Helensburgh.
I remember one evening seeing the loco heading upgrade between Garrowhill and Easterhouse stations bound in the direction of Airdrie. There have been are at least two images of the locomotive coupled to a freight brake van in print. They show the subject in a siding or loop just South West of Coatbridge Sunnyside station. The talk at the time was that it was involved in tests for the overhead catenery on the inert sections between the 25kv and 6.25 kv sections used at that time. I cannot confirm whether this was before, during or after the tranformer/rectifier problems which gave us an Indian Summer of the return to steam at that time."
