Odd design, I seem to recall that they were used for logging. The 3
cylinders make me wonder whether they are triple expansion engines.

Not an odd design, it's a necessary design if you want to negotiate
sharp curves. The Shays were never triple expansion, that was restricted
to marine engines, likely for increased efficiency. The simple expansion engines used in Shays had 3 cylinders and gearing for high torque. They
were used in logging. They were very slow but effective. I know they
were used in Queensland.
Two other types of geared locomotives were the Heisler and the Climax.
Both of these us twin cyinder engines, the Heisler being a V Twin.

I could do one in a Shay in zero minutes. Hint, steam engines don't tend
to require a clutch - 100% torque at stall.

Easy, it uses bogies linked by drive shafts with universal joints. Ideal
for sharp curves on logging, mining or construction railways.

Nah, been an interest of mine since as long as I can recall. In fact,
you can go and look at something similar, a Climax, up at puffing billy
in Belgrave.

https://puffingbillyrailway.org.au/about/rolling-stock/locomotive-fleet/climax-1694/

Similar concept apart from engine orientation. The Shay makes more
sense, the Heisler even more so in terms of engine orientation. Even the Garrett followed a similar concept - articulation.

https://puffingbillyrailway.org.au/wp-content/uploads/Locomotive-G42.jpg

Puffing Billy has one of those too.

What do you mean, overengineered? It's engineered for the environment in
which it operates. The steam engine part is fairly standard. Instead of
a long rigid chassis with big driving wheels, the frame is suspended on
driven bogies (US:Trucks) that provide more articulation of the drive.
You can have a two truck Shay or a 3 truck Shay, either way spreads the
loco weight more evenly on sharply curved, rugged and poorly maintained
tracks providing better traction. There are actually 3 locos in the
video clip, all being 3 truck Shays. Count them! The drive shafts have universal joints in each driveshaft segment. nothing particularly overengineered there. The bevel drives are no different to what you
would find in a truck final drive, the primary difference being that the
gears themselves are exposed. Lubrication of such gears is interesting,
they need a lubricant that adheres to the gears, resists being thrown
off at low speeds, and doesn't pick up too much dirt. Marine grease
would have been the order of the day back when the Shays were new.

I have actually worked with exposed gear systems like those on the Shays
- but they were on face power shovels in the mines. The *grease* used
there was called blackjack and resembled semi-solid tar. It was
definitely a bituminous material and a bugger to get off the overalls.
This is one, now preserved, that I actually worked on.

https://www.earthmoversmagazine.co.uk/digger-man/view,giant-ph-shovel-becomes-a-tourist-attraction-blog-revisited_284.htm

The swing motor and swing circle gears used blackjack as did some of the
gears and couplings on the boom. The Shipper Shaft and Shipper Stick
gears used blackjack.
