I am just wondering how UK steam had less components than US steam. I know that UK had more instances of poppet valve gear, which is pretty cool, but a maintenance access issue. (and have a problem above a certain speed, which is a shame because they are really cool.)
I was just talking about the base components of running a steam locomotive that I thought all post 1920 locos had. Air system, steam system, and water system. What components do US engines have that UK engines don't have?
BTW, I am not being all US is greater than UK here. I am legitimately curious.
Oh, and you can't claim that US engines didn't have as much longevity as UK engines due to how long they lasted after dieselization, you would have to compare prewar figures, which would probably be comparable. The US was able to dieselize faster than the UK since the US wasn't bombed to all hell during the war and had a bunch of spare capital, while the UK had to spend that money on reconstruction so they had to make due with steam.
