kenben Still having problems with by 6-axel ScaleTrains engines going through turnouts. This EMD SD40T-2 engine (out-of-the-box) running at speed 7 (on my NCE Power Cab) will derail 50% of the time through this Peco #6 turnout. The main line is to the right. The straight track on the left is a very short spur. But the front 3-axel truck will jump over the point rail on the left (in this photo) and end up just beyond the frog in the middle of the trunout and shorting out. Running at speed 6 or below it dose not derail. This same engin also comes off the rails in one of my Walthers curved turnouts. I've tried to file down the plastic sections in the frogs. It appears they are low enought to where the wheels do not raise up through the frogs. But derails still happening. My 4-axel F7 and other 4-axel engines run fine through all the turn outs. ???? Don't know why my photos do not show up. ???

I highly doubt that it is a defective turnout. ScaleTrains locos are high quality and I doubt that it is a truck or wheel issue.
It's almost certainly a track-laying issue. Six axle diesels are sensitive to undulations in trackwork, especially side to side. Many will use a six axle diesel to test their trackwork.
I say take up the turnout and check the road bed and subroadbed and re-lay and rewire the turnout again.
