The little trains of the Great War

To illustrate the importance of the military railway track 0.60 m during the First World War, an arrangement was made from film footage shot between 1915 and 1918 by the operators of the film section of the army.

This montage of archive this material system developed by Colonel Péchot (bogies, locomotive Péchot-Bourdon, artillery platform model 1888 and its derivatives, especially the lookout Combed-Canet) and other materials requisitioned or ordered by the army as French manufacturers and Decauville Crochat or foreign, as Baldwin or Kerr-Stuart.

The images also show the construction and maintenance of networks by the men of the two regiments of foot artillery that were loaded. They illustrate the different types of way (on floor, forest, trench, under camouflage or underground), and daily life on the road of 0.60 m, which liaised between the stations of the railway lines standard gauge and the immediate vicinity of the front: transport ammunition and supplies, transportation of men and equipment, locomotive maintenance, forestry work and contribution to the functioning of the artillery.

The narrow path is finally for operators of this new art of the cinema, the opportunity to experience traveling, which shows examples of this assembly.
