You will get the hang of it, Dennis. I just got a long train for my layout rolling in May before I needed to take a hiatus for back surgery. After one glitch of a car derailing, the train has run fine ever since. Knock on wood. Yes, the die cast cars are in the front and the grades are approximately 4%. I ran the train around the layout in reverse once and was amazed it make it without a hiccup. Probably one of those things, I'll never to be able to replicate.
