The zigs and zags should be the same on both rails and if the speed is right small zigs and zags are not a problem, it is when one rail zags and the other one zigs that you get in big trouble. 
Now the same zigs and zags at 40 mph will put you on the ground. 
If the track was in gauge (which I would question) this could have been caused by rock off. There are certain speeds that you just don't want to run especially with covered hoppers.
