Most locomotives of this arrangement were built and served in North America, but there were exceptions. The Bavarian State Railways (K.Bay.St.B) built a total of 25 0-8-8-0T tank locomotives of class Gt 2x4/4 between 1913 and 1923, classified after unification of Germany's railway systems as class BR96. These worked trains over heavily graded stretches of line, mostly as bankers (US: pushers) and were the largest locomotives in Europe when introduced.
