Got a chance to run it for 20 minutes or so. Rear truck derails every now and then shorting out. I don't think that triangular pivot likes my 42" curves. Have yet to actually see it when it comes off. I was letting it run while I tended to other things in the garage so I need to run it when I can just sit and watch for a while. Also one pair of cars uncoupled after about 15 minutes. Still a good shake down run.
