Instruction in reconnaissance and survey work is given to officers while at head-quarters, and a certain number of N.C.O.'s and men are also instructed in railway survey work. Parties, each commanded by an officer, are sent to carry out a reconnaissance and final location of a railway between two points about forty miles apart on the assumption that it is an unmapped country, and complete maps and sections are prepared. The Companies have also undertaken the construction and maintenance of the Woolmer Instructional Military Railway,--a 4 ft. 8½ in. gauge military line, about six miles in length, connecting Bordon (London and South Western Railway) with Longmore Camp. All the plant necessary for railway work and workshops for the repair of rolling stock are provided at Longmore. In time of war the chief duties of a Railway Company, R.E., would be to survey, construct, repair and demolish railways and to work construction and armoured trains. In the South African campaign, when the military had to operate the railways of which they took possession in the enemy's country, some difficulty was experienced in obtaining from the ranks of the Army a sufficient number of men capable of working the lines. As the result of these conditions, it was arranged, in 1903, between the War Office and certain of the British railway companies that the latter should afford facilities in their locomotive departments and workshops for the training of a number of non-commissioned officers and men as drivers, firemen and mechanics, (capable of carrying out repairs,) in order to qualify them better for railway work in the field, in case of need. This arrangement was carried out down to the outbreak of war in 1914. The period of training lasted either six or nine months. In order to avoid the raising of any "labour" difficulties, no wages were given during this period to Army men who were already receiving Army pay as soldiers, but a bonus was granted to them by the railway companies, when they left, on their obtaining from the head of the department to which they had been attached a certificate of their efficiency.
