First Trip to Europe...

There's a 1000 tonnes triple expansion steam engine (the world's biggest working one) in west London. They run it about 7 times a year (Kempton steam museum).

Sure, but when I said working, I meant that it is still being used for what it was originally built for

Oh , I knew that, just wanted to say there's an enormous steam engine here. There are two, but the second is rusty and doesn't work. There should have been three but by the time the second was built it was cheaper to replace the third with steam turbines (much cheaper to buy but more expensive to run). The other steam museum in the area is mostly beam engines, including a "Bull" engine (no beam), a working 90", a non working 100".
