  • This 6.5mm power unit will power our Nn3 locomotive kits and is sure to find its way into many other applications. It is gauged for both Nn3 and Z Scale and comes with an extended driven shaft to allow you to experiment with PTO drive extensions. This extended shaft can be cut to length using regular wire cutters. If you purchased a locomotive from us, and you are purchasing this power unit to operate your kit, please let us know which locomotive kit you purchased or will be purchasing this for since we will need to include the truck side frames for that particular locomotive kit. Also, there is a slight adjustment you will need to make to your already built locomotive. Please see one of the pictures in this listing for this instruction. Please click on the instructions tab below to see more information about this power unit. Also, click on the video to see the units running on the track.

    We will need to send these insured to you, so shipping will be $6.50 for domestic shipping and $12-$15 for International orders.


    Suggestions from Tom Knapp

    A 12VDC train power pack puts out 12VDC (in some cases more) when turned fully flat out. The loco will fly off the track before that happens. At normal operating speeds for the Showcase power unit, the power pack will probably be putting out no more than 3VDC at the track. Operating the power unit flat out for an extended period is impractical at best and careless at worst. In short, just because a power pack says it is 12VDC, doesn’t mean you have to run the train at 12VDC. There are two exceptions to this.

    1. Pulse-Width-Modulated throttles
    These throttles put out short bursts or spikes of voltage – reducing the gap between bursts as you increase the throttle to increase speed. Depending on the manufacturer, these can be 12VDC spikes. In the past I have had some Märklin Mini-Club iron-core motors get very hot is run for long periods of time at train shows using PWM throttles. I have not experienced that heating with the coreless motor Kenji uses. Some manufacturers such as Rokuhan and Varipulse have PWM throttles which are “kinder” to low voltage motors – both coreless and can-type.

    2. DCC
    DCC motor decoders are basically PWM throttles. The decoder can be programmed to get a better range of speed vs. throttle setting for these small motors. Bryan Vianco has a very good tutorial on setting the motor voltage CVs on his web site at tutorialstipstricks. In addition to this, voltage can be reduced electronically using voltage reduction devices between the power unit and track.

    • Tiny but very well made
      I ran it on the flex track I have and it ran very well. I knew it was small but is smaller than I thought which is a good thing.
      I don't have a plan for it with one of the shay in the back of my mind for a future layout .
      Good start for some critters .
      I bought now since I didn't want to miss out .

    • Fitting the new Power Motor to the previously purchased Climax
      Finished up today by adding the side frames and painting. Here’s what I did to make it work for me. I needed to cut off the end of the motor shaft as it stuck out too far and hit the Climax boiler. The screw head on the brass motor cover assembly needed to be filed down to help reduce the
      rear frame height. I actually used a dab of two-part epoxy to level the brass cover to the motor as the screw head kept it from seating level. I let that dry overnight. I then added a shim washer under the front truck to make everything level. I love the results and the wheelbase and overall appearance of this new power truck kit is way more prototypical.
      Next will be the Shay.
