Good evening ladies and gentlemen,
I think it is a captain's captain of the country railway sections (SCFC), in this case the 4th section.
Created and organized before 1914, there are 10:
1st: P.L.M. (Paris-Lyon-Méditerranée)
2nd: P.L.M.
3rd: P.O. (Paris-Orléans)
4th: State
5th: North
6th: East
7th: Noon
8th: East, State and North
9th: State
10th: secondary railways.
In 1917, an 11th section was formed by the 1st section: P.L.M.
After the armistice, a 12th section will be formed by all the networks / sections, for the management and supervision of the service in Alsace-Lorraine.
