Here's what happened to this locomotive after hitting a medium sized 
John Deere tractor at a local grade crossing.  The tractor was "cut"
in half (luckily the farmer was un-injured!(well...at least not physically...)) 
and the locomotive has relatively minimal damage to it! 
Please, please, please... don't try this at home!!!
