Duane-all I can imagine is that since Brits drive on the "other side".
Maybe the owners of the railroad wanted a loco with everything backwards!
Please don't shoot at me, I just report what I have heard.
That is all...

Yes, it is a two cylinder--
you can see that the crankshaft has two "throws" at 90* to each other--
but I too, have to wonder why.
First thing that I looked at was the lettering, to see if someone flipped the negative.
The only way a single cylinder Shay could work would be if there was a way to uncouple the crankshaft from the trucks-
so that it the locomotive happened to stop with the engine on top or bottom center, it could be de-clutched-
and the engine could be barred over to a position where the connecting rod was at an advantageous position for starting-
then reconnected to the trucks-
either that or push the whole dang loco enough to get the engine in this position.
Some time I will relate to you kids the story about the British loco designer who came up with a compound locomotive that-
under certain conditions would try to start both ways at once.
But only if you behave.
