query: What is the heaviest pig recorded in history?
passage: List of pigs
The world record for the heaviest pig so far is held by Big Bill, owned by Elias Buford Butler of Jackson, Tennessee. It was a Poland China breed of hog that tipped the scales at 2,552lb (1,157kg) in 1933.[14] Bill was due to be exhibited at the Chicago World Fair when he broke a leg and had to be put down. At about this point in time, the trend in hog production began to shift to hogs that were much trimmer and very lean.[15]
passage: Union Pacific Big Boy
Without the tender, the Big Boy has the longest engine body of any reciprocating steam locomotive. The 1944 4884-2 series Big Boys were also arguably the heaviest steam locomotives ever built, at 1,208,750 lbs for engine and tender, and 772,250 lbs (engine only) in working order. There is some speculation that the first series of C&O H8 2-6-6-6 engines may have weighed as much as 778,200 lbs, but during subsequent re-weighs of early production H8's under close scrutiny by the builder and the railroad owner, all engines were found to be less than 772,250 lbs .
