For the Steinbeis Railway in today's Bosnia-Herzegovina, the JDŽ needed six heavy narrow-gauge locomotives, which were supplied by Škoda in Czechoslovakia. In order to obtain sufficiently strong locomotives for the light construction of this forest railway, they had five coupled axles. They did not require any carrying axles and could generate a high pulling power with a wheel diameter of 800 mm.
When operations on the Steinbeis railway ceased in 1975, two locomotives came to the Banovići coal railway. Two more were erected as a memorial and another was placed in storage for eventual erection as a memorial. The number 1932 was bought by the Austrian club “Club 760” and has been used in the Czech Republic since 2009 as U57.001.
