Don't you love your modern locomotives that run prototypically slow and smooth?
Here is my first contribution:
Above is a Lionel TMCC D&H diesel made around 2003 that I bought at a train show last year. It also has great sound and smoke. It is effortlessly pulling heavy Postwar operating coal dump cars, a few tanker cars and a caboose.
Here is an opportunity for you to share your Slow & Smooth Power.
