Heres a question that is probably obvious to everyone here but me. On a "modern" steam locomotive, a 4-8-4, for example. I notice that they seem to have two cylinders on each side, one on top of the other. Are each of them cylinders, making them compound engines?

Thanks,
Your deduction is correct; the upper "cylinder" on a simple locomotive is the valve.
