M41

Take a look at http://www.udmes.co.uk/

The track is dual gauge 3-1/2" and 5", extending round most of the park,
with a second 500 feet track for those that don't want to run passenger
trains. Until the larger track was built in the early '80s there used to be
two 500 feet tracks. It's elevated, so an easy driving position, but of
course that means traversers rather than points - when they still had the
two 500 feet tracks, they were very basic and built using the bases of
barbers chairs, which if jacked high enough would lift above the vertical
guides and allow the track section to be spun right round to reverse a
loco. In those days they had a good supply of Welsh steam coal, but these
days they can only get hold of filthy stuff that covers everyone.

The M41 was a surprise, I suspected it would be a lot further South.

I don't recognise it, but I was quite young when I was taken to
exebitions and steam rallies. My brother was into model engineering and
he used to take me around with him, but he is 11 years older than me, I
never knew where we went.
