Long Boiler locomotive

The long boiler locomotive was the object of a patent by Robert Stephenson and the name became synonymous with the pattern. Its defining feature is that the firebox is placed behind the rearmost driving axle. This gives a long boiler barrel, with long fire-tubes. There is thus a generous heating surface area, giving a boiler that is both powerful and efficient.
