I'm new at this, I am setting up a Polar Express display for under my Christmas tree. This year, I'm just going to have an oval with 48" curves and 4' straight away on each side. I purchased the upgrade engine with the dicast tender with the railroad sounds, and I want to know the right transformer to get to eventually operate the cars, and maybe a village. Eventually, I want to do it with the mountain and all that. I'm not afraid to buy a transformer that's a little bigger, but I don't want to go overboard. Any input would definitely be appreciated!
Thanks!
