if you look closely at the pic, the front
centering bracket is partially separated
from the bottom of the girder, indicating
that the load had shifted forward slightly
probably becauae of lack thereof or
insufficient restraints, wonder if cfr49
was in existence back then or would
have been the aar?

These Erie photos tend to be of damages, either to the car or lading. Could the load have shifted and hence the photo?
that also my thought, there is no forward
or backwards restrains at all, i guess back then "g's" hadn't been invented, lol

Think about the dynamics of the three cars going over the approach and crest of the hump.....the load is not secured for extreme vertical curves nor the impact of running into a string of cars after being humped (if the middle car didn’t dislodge the girder as it went over the top!!).

Lloyd's question raises another question. When was the first hump yard
built and where?
Why is there not a Do No Hump sign on this load Lloyd Keyser
