It looks like in the comments of the video they might have already solved this and these cars might be here for erosion control. I don’t know if they got the location or railroad correct though and I didn’t look myself using Google Earth. Interesting video though…
On Long Island in the 1930s a bunch of old cars were dumped on the beach to try and preserve the sand dunes which move all the time. They get uncovered from time to time and then get recovered as the sand moves. Some great photos in that video I must say.
Dumping old railcars for erosion control? Imagine trying to do that now on an inland waterway!
It would be pointless on the Lower Mississippi River.
Yawn…
(1) Probably would lose his mind if he ever saw the Salt Lake Causeway.
(2) “Suitable rip-rap material” back in the day. Plenty of places out here that have no source of large rock rip-rap on the CO-KS-NE-OK plains where anything from old cars and trucks to old railcar bodies were used as flood protection mitigation, especially where you had to drop something in in-a-hurry to keep from losing a fill or bridge to flood water. If it slows down or diverts water, it was good enough. Kellner Jetties could not be be built in a hurry or in flood conditions.
