Look at the size of the boiler !! That would heat a small town or a huge factory!! I prefer an automatic stoker system myself,,, that 'stoker' looks like he's haveing a bad day...
That is about the size of one of the 28 boilers in the titanic!! Each one was three times bigger than a boiler in a big boy locomotive! How many tons per hour? How many stokers werw needed to keep it lit and up to pressure?
