Probably the best place for this but had the privilege of popping to Germany the other day for some train and rollercoaster based silliness

I've never been into US locomotives but just the sheer size of that thing must make it an operational nightmare? Presumably they built triangles to turn them at the end of the line and the minimum curve radius must be measured in miles not chains! RichB said:

American railroads are indeed well-furnished with triangles ('wyes', as they call them) but remember that the giants like Big Boy operated out in the deserts of Utah and the high plains of Wyoming where there is, if anything, too much empty space. So they just built very big roundhouses and 140ft turntables, mechanised coal hopper towers and high-capacity water towers to turn and service them.And don't forget that's an articulated locomotive - the front 'engine' (the front bogie and the first set of drivers) is on a swivelling frame and the four trailing wheels are on a pivoting truck. The front pair of axles on the 'centipede' tender were also carried on a bogie. So the fixed wheelbase is actually not a great deal longer than a conventional eight-coupled steam locomotive. 'Big Boy' could negotiate 10-degree curves in traffic and 20-degree curves at very low speeds in yards.

That's a good demonstration of 'Big Boy's' flexibility. The whole video is a good watch, but the timestamp should start it at the right point (11:33 in if it doesn't).
