 So for the rest of us, what is the answer?

Sorry, the Shay cylinders work just like a regular steamers. Both the up and down strokes are powered. So the tree Shay engine cylinders produce six exhaust chuffs per one revelution of the crankshaft.

Lot's of chuffs - little speed. Lol

I got everything set up now and even set the top speed at a prototypical 15 mph. 

Life is too short not to play with trains, so grow old not up my friends.

There is someone who posts by the name of Geared Steam.   I think this is his website.

If I am in error about the website I apologize.

After many years of procrastination, my Spectrum 80-ton 3 truck Shay is running on the layout. NWSL metal gears and a SoundTraxx sound decoder is installed. Now I am setting up the sound. 

My question is, did the cylinders on the Shay operate like the cylinders on a non geared locomotive? By this I mean was steam pressure applied to the piston on both the downstroke as well as the upstroke creating two exhaust chuffs per cylinder per rotation of the crankshaft? Or was there only pressure supplied on the downstroke resulting in one exhaust chuff per cylinder per revolution of the crankshaft?

Thanks

Jeff
