This device not only saves lives it also saves equipment, a train rolling onto a active track can cause a full out train wreck, it's better to haul your equipment to the repair shop then the scrap yard.

In conductor school for CSX, they showed us some footage of a cut of about 20 cars rolling at a pretty good speed, then derailing and pilling up on top of each other. It was an awesome sight, I'd love to see it again.

To see If it can with stand the pressure of it

I noticed right when the 3rd wheel derails, it looks like one of the fans falls out of place in the screen area

Apparently Bin Laden found this video.
-
Ha, looks like that unit has derailed at least once before
-
@derailexpert Fair enough.
-
they use it at yard exits to derail runaway trains. prevent them from getting into the mainline.

@jorasave The test was to a) set a baseline for the actual dynamics involved in using this particular derail geometry, b) text the unit for strength and durability relative to theoretical determinations, and c) determine the what areas need to be improved.

What I find interesting is how the second axle skid and then spit the derailer out the back, and the third axle did the same. It was only tight for the first one. Kinda makes me wonder if it would survive the second truck, let alone any successive units or cars.

@kleetus92 If you look closely that happens on all three wheel strikes. Common with lower-speed derailments. The wheel lacks the velocity to maintain a full-pass trajectory upon exit. That is, the rate of wheel decent is too great for the longitudinal velocity to keep the wheel flange clear of the derail. You may also note that this movement is withheld to one tie space; by design. Yes, it does survive the second truck and successive cars.
