It is the duty of the Regulating Commission, as soon as it enters on the discharge of its functions and as often afterwards as may be necessary, to advise both the General in command of the Army served by the line of communication and the Director of Road Services as to the station which can be used as railhead and the facilities offered there for the accommodation, unloading, and loading of wagons. On the basis of the information so given the General-in-Command decides each day, or as the occasion requires, on the particular station which shall be regarded as railhead for the purposes of transport. He advises the Regulating Commission and the Director of Road Services accordingly, and he further notifies to them his wishes in regard to the forwarding of supplies to the point thus fixed. These elaborate arrangements for ensuring a maintenance of efficiency along the whole line of communication from the interior to the front equally apply to transport of all kinds from the theatre of war to the interior. In principle, evacuations from the army of sick and wounded, prisoners, surplus stores, and so on, are effected from railhead by means of the daily supply-trains returning thence to the regulating station, where the Regulating Commission takes them in charge, and passes them on by the trains going back to the Depôt Stations, or beyond. Should special trains be necessary for the removal of a large number of wounded, or otherwise, the Director of Road Services communicates with the Regulating Commission, which either makes up the desired specials from the rolling stock it has on hand or, if it cannot do this, itself applies, in turn, to the Director of Railways. For dealing with the sick and wounded, every possible provision is made under the authority of the Minister of War and the Director-General, the arrangements in advance, as detailed in the decrees relating to this branch of the subject, being on the most comprehensive scale. Among other measures provided for is the setting up of _Evacuation Hospitals_ ("hôpitaux d'évacuation") in the immediate neighbourhood of the Regulating Stations, if not, also, at railhead. Elsewhere along the line certain stations become _Infirmary Stations_, ("infirmaries de gare") where, in urgent cases, and under conditions laid down by the War Minister, the sick and wounded _en route_ to the interior can receive prompt medical attention in case of need. From the _Distribution Stations_ ("gares de répartition"), the sick and wounded are sent to the hospitals in the interior to which they may be assigned. It will be seen that this comprehensive scheme of organisation aims at preventing the recurrence of any of those defects or deficiencies which characterised the military rail-transport movements of France in the war of 1870-71.
