I understand that the two narrow gauge locomotives that used to work the Dolcoath railway from Stray Park to the stamps, and from Harriet Shaft to the stamps, were sold at closure to C & M Powder Co. Ltd at Treamble. Does anybody know anything about this company at Treamble? There's no info on the Web!! Were they something to do with the iron lode at Perranporth? When did they cease to exist? Whereabouts did the Treamble railway run?
