The "Guarda tren" is the equivalent in Argentina to the Conductor on US railroads, until 1992 this basic bay window caboose was their refuge in the tail of the freight trains, without radio communication with the locomotive, they only protected the end of the train by regulation, occasionally at night they used their hand lantern to tell the engineer that the train came complete, it was very rare that trains in those times had a continuous braking system.
