Which specific boiler type did the Tom Thumb locomotive incorporate?

Answer

Vertical fire-tube boiler

The Tom Thumb featured a unique vertical fire-tube boiler design. This engineering choice allowed for quicker construction and addressed the need for immediate, functional results during a time when standard locomotive architecture, such as horizontal boilers used in Britain, was still being adapted for the distinct challenges posed by American track conditions and nascent boiler-making techniques.
