  1. January 2023 Tech Tip - Coupler Heights and Trip Pins

    I am going to go over coupler heights again since I am still seeing so-called “HOW TO VIDEOS” on YouTube that has so much bad information they need to be removed. I am telling you, the amount of bad, misleading information on YouTube is disheartening!

    I can’t emphasize this enough, check your coupler height with a height gauge, setting your coupler height using the centerline of the couplers, and make the necessary fine-tuning adjustments. These adjustments need to be precise for proper working couplers. “Good enough” doesn’t work for trouble-free operation. Checking your coupler height is something that should be, second nature for everyone in the hobby. “Scale” couplers make this even more critical because the coupler pulling face is smaller. See the below details.


    The trip pins are factory set, and if your coupler is mounted correctly and set to the Kadee coupler height gauge, your trip pin will not need to be

  3. October 2022 - COUPLERS, and The People Who Make Them….

    COUPLERS, and The People Who Make Them….

    Kadee Quality Products Company has been the "De-facto Standard" for Model Railroad couplers since the early '70s. It has expanded its line of fully functioning Knuckle couplers over the last 40 years. From HOn3 to G scale for Reliability and Functionality.

    The prevalent Whisker® version in “Scale” and Standard head HO gauge has overtaken the standard shank centering system for their "ease of use," and the same dependability and reliability modelers have come to expect from Kadee®. Our #148 Centerset Whisker® coupler now outsells "Ole Reliable” NO.5® and #158 “Scale” Head Whisker® coupler outsells its predecessor #58.

    Please Note that ALL these couplers will work together provided you have them at the proper height, which you can check with a coupler height gauge, either a #206 or #205.

    To dispel any rumors, Kadee is not discontinuing our #148 coupler or any other couplers.

    Bulk packs of the #14

  4. September 2022 - Patriotic car

    I realize it has been only a couple of weeks since our August release, but we need to get back on schedule. So don’t forget about our August 2022 Patriotic Car release.

    We have been getting a lot of positive feedback on this design, with the Statue of Liberty and the Constitution of the United States on the side of the car.

    I feel the artwork represents the strong American spirit that we all share in one way or another that everyone should be able to relate to, if you leave politics aside.

  5. July 2022 - Factory Packaging

    I was at the 2022 National Garden Railway Conference in Denver last month assisting the attendees with the Large Scale Kadee® product questions. I had a lot of inquiries about our large scale metal wheels and trucks and some I didn’t know the answer to. I can admit this, so when I got back, I looked up the technical info I was ask about and updated our large scale wheel product information on our website. Please check out the large scale wheel product pages #950, #951, #960, & #961 as we have new technical info on the pages.

    I keep getting e-mail questions on how may large scale wheels are in the factory packaging even though we have a clear product description on our webpage. We discovered what has been causing the confusion with the 950, #951, #960, & #961 quantities. There had been some resellers opening the Kadee® factory packaging and removing our protective packaging thus changing the quantity & reselling the #950, #951, #960, & #961 as 4 Axle sets instead of the factory 2 A

  6. June 2022 Tech Tip - Drilling and Tapping Holes

    I am thinking this month we are going to go over drilling and tapping holes. This may be a subject that intimidates some of you out there. Others it may seem like second nature and wonder why I would go over such a subject. Everyone has to to start somewhere in the hobby and people have all different skill levels. For those who are new to the hobby and may not have grown up around tools, working on cars or what not, you may not even know what drilling and tapping holes is referring too it is OK.

    I keep getting people asking questions about what glue to use; wanting to glue gearboxes on to cars instead of drilling and taping screw holes to attach the coupler gearbox or replacing trucks. I even have people asking questions about using and were to get self taping screws for mounting couplers and trucks because they don’t want to tap a screw hole. Lets first just say gluing gearboxes is not recommended and should be avoided. A glued on gearbox is permanent and if your coupler h

  7. May 2022 Tech Tip - Large scale coupler style differences

    I have gotten many questions at shows & by e-mail regarding what is the difference between our two styles of Large scale couplers; the AAR Type “E” coupler and our original style of coupler that are available in (O-scale 1:48, #1-scale 1:32 & G-Scale 1:22.5). Yes, both designed are based on the common Type E coupler. Our original coupler style has an exposed knuckle spring with minimal details; our AAR Type “E” coupler has a much more prototypal appearance & hidden knuckle spring. Know that it is large scale season it is time to go over the subject and the features that make the couplers different.

    Let's just start out with the obvious the AAR Type “E” coupler has a much more prototypal appearance then our original style of coupler. The AAR Type “E” coupler contour with visible Kadee® casting marks to better replicate the prototype coupler. One other big feature if it hasn’t jumped out at you yet is where is the Knuckle spring? Yes, that is right the AAR Type “E” couplers

  8. April 2022 Tech Tip - Coupler Mounting Height

    I am going to go over coupler mounting height again and again, until I stop seeing or hearing about peoples conversion video’s posted on the internet that show people mounting couplers at the incorrect coupler mounting height on “how to videos”. Couplers barely hooked together and then bending the trip pin is not acceptable; even if the coupler is off 20 to 30 thousands checked with a coupler height gauge is not “good enough” for trouble free operation. If you don’t want your cars coming apart when you are running them then you need to take care you have the coupler mounting height correct. “Scale” couplers make this even more critical because the coupler pulling face is smaller.

    Example: When you go over that transition on your layout pulling your favorite cars the couplers knuckles will raise and lower keeping the cars connected if you have set the mounting height of the couplers at the centerline, this gives the most available coupler movement without the couplers slippi

  10. January 2022 Tech Tip - Coupler Height Gauges

    The Coupler Height Gauge for the scale you are modeling is your best friend when is comes to trouble shooting, installing couplers and uncouples when used correctly. If you are trying to install couplers or trouble shoot couplers without a coupler height gauge you are just spinning your wheels. Trying to use an existing car to set your coupler heights is a bad idea and will not end well. If you think you need to bend the trip pin then your coupler is probably at the incorrect height. Trip pins are factory set and should not need to be bent if coupler is mounted correctly. When the coupler height gauge is used correctly whether for mounting uncouplers or mounting and fine-tuning couplers; your couplers should operate trouble free*.

    *Coupler height gauge or coupler design can’t fix bad track or incorrectly setup equipment.
