Because as they hadn't figure out how to recycle the steam, huge puffs of it was released as the engine worked.
The first successful steam engine was Watt's pumping engine. The first sucessful steam locomotive 'The Puffing Billy' was called such because the puffing sound it made going uphill (under load) reminded people of a puffing billy goat.
it was called the puffing billy basically because steam is produced from its chimney.it was invented by Scotsman James in 1775.
A stokker.
Maybe you are thinking of Stephenson's railway engine The Rocket.
The cause of white puffing smoke in a diesel is the crack pipe ventilator seal. Fix that it keeps the crack inside.
George Stephenson designed the first locomotive, designed for hauling coal, in 1814. He called it 'Blucher' after the Prussian general Gebhard Leberecht von Blucher.
