Classic Collect

Hi, I am doing a retro review article on the Triang class 33. Does anyone have any recollections of this loco? Also when did it first appear etc, On another point I am trying to build a recreation of a 1950's Triang layout with standard track. The class 33 pictured has had new brushes and wheel sets fitted, but will not run on Triang standard track. It runs OK on normal modern track. On the Triang track it will not go round even 2nd radius curves, without the gears screaming and slipping. I have tried to pick the least warped and twisted track with no joy. I know of the link below. http://www.tri-ang.co.uk/indexlocoD.html Regards,Geoff.
