New Nn3 power truck from Showcase Miniatures

[TomBo3]

Just got this new Nn3 power truck today from Showcase Miniatures. The photos show it beside my Searails power truck. The one from Showcase runs smooth and slightly slower then the Searail unite. It looks like the new power truck will fit wherever the searails one will with some slight modification to the loco you want to power. If you want one, better order now as the first shipment to Showcase is only 20 unites. Tried to add pictures but a popup states I'm not allowed to add pictures???

It looks smaller and with a shorter wheelbase to better match their Shay kits.

My Showcase Miniatures Nn3 power chassis arrived yesterday and I also took some comparison photos next to the Searails PowerMAX. This new power chassis is meant to be a replacement for the now OOP Searails PowerMAX which was used in the Showcase Miniatures Nn3 Shay & Climax kits. The wheel base on the Searails unit is around a scale 5’ 3/4” and the Showcase Miniatures scales out to 5’. The rear truck side frames on the new Showcase power unit attach to an etched metal box (comes with the power unit & you have to fold & assemble) that fits over the chassis. If you have one of their Climax or Shay kits just specify which kit & they’ll include the side frames when you order the new power chassis. The rear truck side frames on the Searails unit were attached by first removing the bottom plate and then replacing it with a new cast bottom plate & side frames from the kit.

Showcase Miniatures on left, Searails on right. My initial test run results were similar to what TomBo3 saw...IMHO it seems to run better (and is quieter) than the PowerMAX but your mileage may vary.

Any problems with wheel wobble on the Showcase truck?  It took me 3 Power Max chassis to get one with straight wheels.

No wheel wobble that I could notice Chris. The PowerMAX in my photos does have some wobble when it runs and requires additional weight on top to improve electrical pickup. I'll try to post some videos of each once I get them uploaded to YouTube

Cool. The short WB should look better under their Shay as well.

Some videos of both power chassis running on test track. My power pack is a Rokuhan RC-02
