Yeah, I tried contacting MTH for a couple of months. The techs there thought at first I was doing something wrong. Then they thought the engines I was comparing the speed with maybe off. I have a ton of their engines. I know enough to do damage anyways.
The first engine that did this was a ps2 that I just sent out to be fixed and paid for it and shipping. That one also should have been warrantied. MTH did not respond.
Now I have a brand new one with PS3 and they won't fix it. So I will. I love their products but I can't stand dealing with them anymore. Urrrgggg!
For anyone into G scale, every product I've ever gotten anyways, needed work. So this is not a surprise.
So what tech will make me a special PS3 reader with a spacer?? They'd have to admit there was a problem first. I must be crazy that it's that fast.....

I need to start my own MTH service station! 
To bad, I don't do electronics!

Against my pride and better judgement, I just took a dremel to it and now it runs correctly. Yuck. done.
