The Bury copper-covered hemispherical firebox gave rise to the nickname, while the bar frame distinguished this class from the more common plate frame. The boiler was considerably bigger than most locomotives of the time.
These were the first locomotives for the Furness Railway, with number 3 leading the line's first passenger train on 24 August 1846. Most of their service was devoted to iron-ore and slate trains between the quarries and mines and Barrow-in-Furness. Number 3 was retired in 1898; it still survives and was run as recently as 1996.
