Hi

In the mid to late 1970's when Banana Splits and then Noel Edmonds Swap Shop 
was shown on Saturday Morning TV, there used to be other 'filler' type 
programmes as well. One of these 'one-off'' programmes was called (I think!) 
"Trains Unlimited" although it may have been "Railways Unlimited". It was 
only a short film showing model railways starting off serenely and then 
going out of control to various musical accompaniament. I seem to remember 
the controller pulling the plug but this seemd to make it worse (but my 
memory is not what it used to be).

Does anyone else remember this very entertaining piece of cinematic history?

If so, would you know where to get a copy as I would love to get hold of 
one.

Thanks in advance

Mike
