The analysis of geographical spaces and the way in which physical-geographic elements influence the planning and conduct of military operations is related to military geography as a component of military science. From the military point of view, the parameters of the relief are of particular importance. In this respect, in the Bârgău Mountains, the mountainous landforms, with slopes leading to the lack of viability, then the high ridges and dominant points that offer wide views, the regime of the currents, the rain, the harshness of the climate in different seasons, the high temperature variations and atmospheric pressure, are elements that oppose or which, on the contrary, can be used as a real weapon against the enemy
In the context of the World War I outbreak and given the lack of a direct railway line between Transylvania and Bukovina, the Austro-Hungarian army is forced to find a quick and operative solution to the supply of weapons, food, but also to restore the supply to the Austro-Hungarian empire with manganese ore, dolomite, lumber, cereals, animals and other goods provided by Bukovina. Therefore, they considered building a fast link between Transylvania and Bukovina, along a spectacular route, namely, the Prundu Bârgăului-Vatra Dornei railway line. In the successful realization of this great project an ingenious, even revolutionary solution was found for those days: the construction of a railway line with normal gauge, adapted to trains and the petrol-electric traction, according to a model that was used and successfully put into practice since 1912 in Austrian Tirol. The works were completed in a very short time, even though there were very harsh working conditions and the route was extremely difficult. Both the Austro-Hungarian army and civilians from neighbouring villages and prisoners of war contributed to this success.
Tourism as any other human activity causes a negative impact on the environment when the general rules of behaviour and management are not fully respected. Actually the growing development of tourism and the increasing number of tourists in the area, have had a negative but prominent effect on the local environment as well.
The former petrol-based electric railway, built during First World War originally served for the food and ammunition transport meant for the armies, which had settled down the mountain peaks nearby, today in the area of Vatra Dornei or Cârlibaba and which were guarding the passage towards Transylvania. They were often used to evacuate the wounded and for commercial purposes as well, in order to transport cereal and many other kinds of grains at the blooming 1916, all this acquired from the requisitions of Bucovina and even from the smuggling or imports of Romania, which still enjoyed neutrality by the time.
