In stark contrast to the rudimentary road network of the time, the railways could transport large quantities of supplies, heavy equipment and troops rapidly and efficiently.
For operations to the front lines the military developed its own system of field railways (Feldbahnen), usually built to a narrow gauge.
The Heeresfeldbahn is tied to this fixed infrastructure; under artillery bombardment or other acts of war it is not flexible enough compared with lorry transport.
Due to these disadvantages, the Heeresfeldbahn completely lost its importance in the second half of the 20th century and was replaced by road vehicles which were now more technically advanced, cross-country capable and did not require specially trained crews.
Transportable Feldbahn track materiel, locomotives and wagons were often sold to civilian companies after the cessation of hostilities and the politically driven disbandment of the troops responsible for them.
For example, in some peat works today there are still track sections from the Imperial Austrian Military Railway to be found and in Feldbahn museums there is a variety of steel relics to be seen.
