How about we mix things up with some prewar articulated streamliners?
On the tinplate loop, I'm running my Chicago Flyer Green Diamond set. This is probably one of my favorite American Flyer trains, I just love the wedge-shaped nose on the locomotive.
On the inner mainline, I have the set of 1700 series cars that I restored last year behind the set of prewar period, semi-scale diesels that I usually run them with.
On the outer mainline, my MTH command control Hudson is hauling a set of Lionel Classics Railchief cars. These are a very heavy set of metal-bodied cars that need a very strong locomotive to pull them.
Quite a bit of tinplate thundering around the layout! Here's the video so you can hear for yourself.
