A Garrett in Zimbabwe:
One thing about Garretts made no sense to me: Why the cylinders were placed as far as possible from the boiler. That means that the steam lines from the throttle dome have longer to run and that the exhaust from the cylinders also have further to go before they are exhuasted out the blastpiple. The engines of a steam locomotive don't really care in which direction they run; see, the Southern Pacific's Cab-Forwards.

If the cylinders were at the other end of the driver units, I think they'd interfere with the articulation joints.
True, they'd have to make an already-long locomotive even longer. Which means bigger turntables, etc.
But it also allows for a lower locomotive, plus the equivalent of two engines in one.
Wouldn't it have also been an issue that as water and fuel were consumed, the reduced weight on the drivers would have had an effect on traction? Still, a handsome locomotive.
