[modeleng] Re: Winson Jubillee

Tim,

Three cylinder locomotive engines were not unknown over here in the
Colonies, but the only one I remember ever actually seeing is a switcher at
the Museum of Transport in St. Louis.  It seems that the valve motion on it
is somehow worked by a system of levers on top the pilot beam.  They are
connected to the valve rods on the two side cylinders and through some
trickytrac movement, they operate the valve for the centre cylinder.  I have
a close-up photo of all the banjo work somewhere if I can find it.

What is the problem about the cylinders not being in line on the Winson?  Is
the centre cylinder lower than the other two?
