They actually date from 1987 and were originally 35 two coach trains used in the West of England and on the Marches Line .. they were fucked up in the early 1990s by being converted to 70 single coach trainlets. You are actually getting new Swiss designed "Flirt Trains" trains in Norfuck over the next couple of years. Most of these little "darlings" are going off lease but actually migrating elsewhere. I expect that they will be still around in 20 years time. "White Knuckles Brian" and "Happy Tom" (R.I.P.) of Crewe used to get 85mph out of them.
