[@POOHEAD189] Your story is more exciting than mine. That was a narrow escape. Happy to see you alive, bro.

I used to work for a railroad as a conductor. I was spotting an empty "boxcar" at a customer's dock. I backed into the customer's spur and tied my empty onto an existing empty rail car already on spot. Since the existing car already had a hand brake on it, I did not put one on the new car I was leaving. I assumed the hitch was good and that the knuckles would hold the car in place. I closed the air valve on the last car I was taking back into the rail yard tied onto the engine and then pulled the lever to separate from the car I just spotted. I told the engineer to take it ahead over the radio and then had him stop just past a derailing device on the customer's track. The spur was on slightly elevated ground. We shoved the train up hill to spot the car. If a car were to get away on the spur track, it would roll over a derailing device before it re-entered the yard. I stepped between the rail to put the derail back on the track. I heard a noise and looked to my right. The empty rail car, weighing roughly 25 or 30 tons was heading at me, at about two or three miles an hour. When I spotted it, it was about ten yards away. I yelled an expletive and dove out of the way. The runaway rolled over the derail and went on the ground. I was safe, but shaken. Apparently, the hitch was not good, the knuckles opened allowing the downhill car to roll away. The air reservoir used to hold the brakes had bled out. There needs to be a high amount of air pressure in one reservoir and zero psi in the other in order for the brakes to hold. The reservoir that should have been under pressure, was also at zero psi. When the two reservoirs have equal air pressure, the brakes release.
