apologies if this has already been posted, but I searched and couldn't find it here, thought it should be shared :O
That would have needed several Kardashian-sized cabooses on the back-end of each of those forklifts to try to balance out that load.I think the height was to get over the bolsters that held the rails in.
Why lift so high? Isn't that one of the principles taught in forklift training school? Once the side supports had been cleared they should have been able to back out.
Also notice the way that the ballast falls away as the forklifts try to back out. Only for the excessive size of the load (causing it to fall forward), it may well have come back onto the forklifts with possible fatal results.
David, note the side supports. Once the rails hit that, then it was "all over red rover" for the wagon. The momentum would have taken the wagon onto its side.
