I'd always held back on trying one of these Showcase locomotives, mostly because of the 4-wheel pickup and the non-functional front truck. I've done enough 4-wheelers to know how erratic pickup can ruin an otherwise great model design.But after messing with my Nn3 Climax A, I discovered that Rokuhan SA-001 chassis front truck, a Z scale version of the Kato chassis. End axle pickup, 4x4. If it worked, this makes Walter Vail's design about perfect, nobody can argue with the quality of the parts.Decided to gamble and see if it could be adapted and put on the Showcase Nn3 bitty Shay. Long story short, complete success. And getting wires to the front also let me wire it for dual directional headlights. Man, this thing is SMALL....!...snip...This really, really runs well, good low speed, dependable pickup - now. One of the best critters I've built yet.
Ack! Nice! Don't we get to see it run! And I see a gear under there. Did you power both trucks?
