Frequently Asked Questions

Other Scales

We do not sell any N or Z scale products. Kadee® manufactures HOn3 through G scale products only. We recommend that you contact Micro-Trains at for N and Z scale information.

Kadee® Quality Products and Micro-Trains split into two completely separate companies in 1990. Micro-Trains manufactures only N and Z Scale products, and a few HOn3 products.

We’d like to but we have so many projects going on and a very long list of future projects. So unless something becomes a priority we really do not know when we’ll get to it.

Back Ordered Products

We rarely, if ever, have back ordered products.

While we can't control the inventory or business practices of hobby shops, we do provide Kadee® products factory direct when they are not available from your hobby shop.

Some hobby shops may not order directly from a Kadee® and instead may use a distributer that might not stock all Kadee® products. Please feel free to order direct from us at anytime.

New Products

We do not announce new products prior to their release. The production of new products is dependent on demand and priorities.


No. We do not offer bulk orders or quantity discounts.

Coupler Conversions

Models with Factory Knuckle Couplers are easily converted by using our #148 or "scale" head #158 Whisker® Couplers.

If your model does not have Factory Knuckle Couplers please visit our Coupler Conversions page for our complete list of conversions.

Coupler conversion recommendations are based on: manufacturer, type of model, overhang, end-of-car clearance, and if the original coupler mounting will be used.

"RTR" Cars

We use an industrial paint company to formulate our paint and custom match the colors we need. Unfortunately we do not have any infromation regarding alternative aftermarket paint colors that match our paints. We leave it up to the modeler to find a paint match when needed.

Also, the bodies and doors of our cars have a thin coat paint on them and the add-on detail parts are unpainted Acetal plastic. We spend a great deal of time getting our paint and plastic to color match.

Kadee uses a water base paint for the bodies that matches the color of the styrene parts. The other parts are unpainted Actel Delrin plastic.

The steciling is Silk Screen Enamel and for those who wish to remove the stenciling Acetone or Acetone base solvent works the best but you can also use Alcohol but there’s a bit more scrubbing. Both Acetone and Alcohol will also remove the paint which leaves a shiny area.

We have not yet decided on our next car. We have quite a number of projects we are presently working on so it may be quite some time before we start another car project.

Our main focus is on our coupler production, which is our primary product. Our freight car line is only a secondary line.

We sure can. And we have done so several times for customers. Have a custom run of the finest cars produced for your club or organization. We require a minimum order of 300 cars. Completely made in the U.S.A. Call Kadee® today at (541) 826-3883.

As a matter of fact we do sell to several model makers and we are certainly willing to sell to any manufacturer that wants quality couplers on their models. The main issue is the bottom line the manufacturers are willing to pay for couplers and their lack of regard for the modelers desire for quality couplers installed at the factory.

Our 20 and 30 series couplers have very strong plastic shanks and heads but have metal knuckles (moving part of the head).

Our 20 and 30 series coupler have very strong plastic shanks and head but have metal knuckles (moving part of the head).

Perhaps, eventually. But it really won’t happen for a very long time. The #5 coupler is still the back bone of our coupler line, however, any new HO Scale coupler we make will have the Whisker® centering spring type of shank.

Yes, The Scale Head couplers were designed to function with all of our other HO Scale couplers.

The 140 Whisker®® Coupler Series is complete and replaces the 40-Series couplers that have been discontinued.

We will not be making any Scale Head Offset Couplers for a number of reasons.

The 2-56 x 1/4” and 2-56 x 3/8” screws are the most common for mounting couplers. See Machine Screw Sizes Chart

Most of the time body mounted couplers are operationally better than truck mounted couplers.

Our #148 Whisker® Coupler is most often a direct replacement for EZ-Mate, McHenry, or Accumate couplers.

Electric Uncouplers

The most common reason is the wire on the coil has a clear thin insulation which needs to be scraped back for the wiring connections. Because the insulation is clear it is often overlooked.

Trucks and Wheelsets

Our self-centering trucks have a special wedge shaped bushing in the bolster that secures the truck to the car. When you lift the car the truck drops onto the wedge which aligns it with the length of the car. This reduces the fooling around you have setting the car on the rails. When the car is setting on its wheels the trucks are disengaged from the wedge and a pivot freely until the car is picked up.

The 2-56 x 1/4” and 2-56 x 3/8” screws are the most common for mounting trucks. See Machine Screw Sizes Chart.

Our trucks are designed to mount on a flat surface which usually requires that you trim off any post the original truck pivoted around. Our trucks, as well as most after market trucks, are designed to be mounted with a #2 size of screw.

The term Code 110 and Code 88 relates to the width of the wheels.Code 110 wheels are .110" wide and Code 88 are .088" wide.

Code 110 wheels are the common (or standard) width wheels and Code 88 are what is called "semi scale" and are used when the modeler wants a more prototypical looking wheel width.

Track code and wheel code have no relationship meaning Code 110 and Code 88 will run on most any code of track. Track code is simply the measured height of the rail, code 100 is .100" tall, code 83 is .083" tall, code 70 is .070" tall, and so on.

We do not make passenger car trucks. We only manufacture freight car and caboose trucks.
