Specially designed American locomotive for the battlefield.
Easy to build and maintain. The
result is a combination of riveted and welded
structures, a rods frame, Crampton fire box with a grid surface of 1,78m², relatively large wheels (1.372 mm) and cylinders, consisting
of two assembled castings which also form
the support of the smoke box. The
construction of the boiler gives the engine a
typical American appearance.
