I tried to make my own Nn2 things a very long time ago. I was able to get a couple of sets of wheels and a little vee-tipper built. Then I build some track but a powered engine was way beyond my means. After watching the Craft video on Youtube about the turntable I went to their stream to see what else they might have on offer and saw this train set:
N scale, 3.75mm gauge. Check out that little Koppel steam engine. Boy that’s cool.
