In my railroad career in the U.S. we rerailed MANY cars with frogs, wood blocks, tie plates, rocks, whatever was available. So far as I know this still happens regularly. If this was the first car presumably it was one of the full length domes. Those are heavy, top heavy, and have disc brakes....in general not good candidates for improvisation. Easy to damage the discs or rotors, and you don't want to turn one over. It is not so much that the SLURG guys were not as resourceful as your Ecuadorian friends, they simply had a much bigger problem with a lot more at stake.
