We have some really unique display pieces not seen in many museums! These are early “end-of-train” devices (EOT), also known as “FRED’s” (Flashing-Rear-End-Device), these electronic devices started out as super simple devices that only measured the air using a hose attached to the train air line and a gauge on the side of the device that allowed for a visual confirmation on the pounds of air pressure registering at the rear of the train. Years prior to these devices, the caboose was where the gauge would be found. However as the railroads worked toward cutting overhead by reducing the labor force needed to operate a train, the EOT quickly became the viable replacement for the caboose, eliminating two job positions and put the Conductor in the cab of the locomotive with the engineer.
Seen below are a couple examples of EOT’s. The yellow units are basically flashing markers that were used, predominantly by Amtrak back when they were running the express boxcars on rear of their trains. They do not do anything other than flash, providing a visible indicator of the rear of the train. Normally Amtrak passenger cars (even private cars too) are equipped with two red markers, positioned on both sides of the end of the car.
The other two EOT’s are from fright railroads. The marked one obviously coming from Conrail and the unmarked one coming from the Southern Pacific Railroad.
All four units operate via battery power. The only major differences between these older models and those seen today are weight (today’s models are lighter), air driven battery charger, GPS telemetry, radio communications and can be controlled from the head end of the train in case of an emergency. We are very fortunate to have these unique pieces of railroad history as part of our collection!
Come on by, Saturdays from 10 to 5, and take a look at all the cool things we have for display! We also encourage you to join our organization! We have multiple division, found in multiple counties, Bexar, Wilson and Jim Wells Counties! We’re a rapidly growing organization, faster than others in the region! Come be a part of the team and help grow the organization!
