Wow! Nice photo. The wheels look so fragile for the weight they carry. Also I notice they have different amounts of counterweight cast into them. How did they know how much to cast into each wheel? Maybe due to the position of the connecting rods?
Now that you've mentioned it, I got curious to. Found this on REDDIT.
Counterweights for the valve gear linkage, the part opposite the weight should be of similar mass so that the rotational force isn't off balance. Just to add, this is also why some are bigger than others. In the photo here the counterweight is bigger on the second wheel because that wheel has more things attached to it, so needs a bigger counterweight.

Almost, a work of art, just to pull 100 tons of cargo along a steel rail.
We need to be able to see (reproductions) steaming across America, today.

Ha Ha..well spotted John. Just before I was going to 'add' some shots of some very old locomotives my mobile phone went off (I was expecting a call from my local surgery) and somehow in that distracting moment I must have pressed send...It's an old age thing!
Looking forward to more
