Cogar;
More likely than not the cabinet in question was probably never used by the railroad, I was just guessing out loud. But, I have had some oddities that did have a RR connection. One that comes to mind was a tall (7’), narrow, RR marked cabinet with two padlocked doors. One side had a stretcher inside, while the other side held a 1884 Springfield rifle with attached bayonet, and a compartment for about 10 rounds of ammunition. There were printed orders that stated use of the weapon had to be under the direction of the station master. Strange setup...when would you have the need for a stretcher along with a rifle and bayonet?
I grew up next to the tracks, and was awestruck by the way the RR did things at times
