and Arthur Koppel introduced
narrow gauge railways into new markets around the world,
revolutionizing transportation of bulk goods. Initially O&K
were reluctant to get into the manufacturing of locomotives, instead
they were focusing solely on laying the rail tracks and purchasing
from other distributors.
It wasn’t until 1890 that O&K opened
its first locomotive factory. When the company became more serious
about locomotive manufacturing, it purchased a new factory in Drewitz.
The new facility was designed to manufacture 300 locomotives per year.
However it produced 100 locomotives its first year, 200 in its second
year, and fluctuated the following years until it reached its potential
in 1905. From then on, the factory excelled in production, and by 1908
it was producing 600 locomotives per year.

O&K delivered 13.264 steam locomotives to almost all
in the world, many of which are still in use. O&K is
worldwide famous for its field, forest, plantation and industrial
narrow gauge locomotives.
Design of narrow gauge locomotives was
mostly standardized. The locomotives were built in a number of sizes,
providing a range of horsepower’s. There was a choice in
four, six and even eight & ten coupled designs. They were built with
inside frames or outside frames. Outside frames were used in case
of very narrow gauge, in
case the wheel gauge had to be adjustable and for locomotives with flexible hollow axles patented by O&K.
In 1945 O&K stopped building steam locomotives.
