just received my new Lionel 2233151legacy diesel DD 35 SF 1650 22 inches long, dual smoke stacks, Bluetooth etc. I run it on my two long outer loops with 72 curves. I can also run it on my inner routes which are minimum 54 curves. It is designed to run as low as 42 curves. See my video on following post . It may not fit in next post but it will be there.
