Now that you have dusted off your large-scale rolling stock and locomotives, it is time to see how your outdoor layout held up over winter. Some track work will inevitably have to be done to get all your cars rolling reliably on it again. Have you noticed the longer modern cars get, the more sensitive they are to run on track? That is because the length of the car magnifies every dip, bump, or transition in the track.

Kadee® has a quick and easy solution for anyone with some of those fussy cars that like to slip apart on your layout. Now you can change out your G-Scale standard or type “E” Kadee® Couplers to one of the NEW “SE” top and bottom or SBE bottom shelf Kadee® couplers, and you will not be leaving your favorite car sitting on the siding anymore. The “SE” top and bottom or SBE bottom shelf Kadee® couplers will allow cars that don’t stay coupled from track imperfections to stay coupled up over those grades, bumps, and dips—no need to struggle with those slight track

#1 To keep your locomotives operating to their peak performance, regular maintenance is required. Just like your automobile, you have to check the tires. The Kadee® Speedi Loco Driver Cleaner cleans your locos drive pickup wheels, spinning away dirt and debris so the wheels make good contact. The wheels picking up the current from the tack is essential for your loco to run as smoothly as it can.

#2 Never use grease or any other liquid lubricant other than powdered graphite on couplers and trucks. Dry powdered graphite is the only lubricant Kadee® recommends. Liquid lubricants can react to the materials used in couplers, gearboxes, and wheelsets, and trucks are made from shortening the life expectancy. Liquid lubricants also attract dirt and debris, drying out over time and making for a sticky, messy cleanup. Lubricants are supposed to make parts move freely without a sluggish response.

From a modeling stand point, the majority of couplers on the market represent the Type “E” coupler, but in general appearances, the “scale” couplers presently marketed can be used to represent the early Janney couplers. This means modelers in any scale can use knuckle couplers for models back to the 1880s and be, at least functionally and in general appearance, prototypical.

Specialty couplers began to appear experimentally in the late 1930s and in 1947 the Type “H” was standardized. The Type “H” sometimes known as the “Triple Lock” or “Tightlock” and, because of it’s safety features, was used on the newly developed high speed passenger trains.

The first interlocking coupler use for freight cars was the Type “F” coupler introduced in the 1940s was made Alternate Standard in 1954. The Type “F” coupler is basically a Type “H” coupler with an additional bottom shelf. Then in the late 1960s the top and bottom shelf Type “SF” coupler was developed and standardized in

Ever since we invented the Kadee® Magne-Matic® knuckle coupler system over 60 years ago, we have taken great care to provide accurate instructions for every one of our products. Our product instructions describe the best way to install and use Kadee® products to ensure a trouble-free experience. Please follow the instructions provided in your packaging. Other sources of installation guidance (such as YouTube videos or online forums) may omit important steps from our instructions that could result in damage to your models or unsatisfactory performance. If you are wondering why something is not working correctly, it is probably because one or more of the most basic critical steps were skipped in the instructions and/or the coupler fine tuning process.

Let's go over the important basics:

Our large-scale couplers represent the common Type E coupler and come in two types and two scale sizes "G" scale 1:22.5 and #1 scale 1:32 scale ratio. Our original coupler style has an exposed knuckle spring with minimal details. Our newer style AAR Type E (New Generation), has a much more prototypically detailed coupler head, and the knuckle spring is hidden inside the head and cannot be seen. Both styles are completely compatible with each other and use the same draft gear boxes, so the conversion information is the same for both. It is just personal preference on what coupler style you prefer to put in your equipment.

Most Large Scale manufacturers use their own proprietary knuckle couplers or hook and loop couplers. As many modelers have found out, some may or may not be compatible with each other both operationally and coupler mounting heights. Kadee® couplers, when installed correctly and using our Delayed Magne-Matic® Uncoupling system, are a complete "hands off" coupler system. Kadee® couplers can be fitted to almost any model which eliminates any compatibility issues.

I regularly get questions from people confused and/or overthinking coupler mounting. I think it is more so overthinking about coupler mounting, not reading the information we provide, and not using the coupler conversion information we provide online. This is something that is a much bigger problem than one might think. This is not just from new people entering the hobby; this is from the hobby veterans also. I will break this down into different common scenarios.

HO Scenario #1: I have an old Example (UP 1234 car) or (B&O loco that has yellow lettering) I picked up; what at coupler do I use on it?
Sorry, we need the make and model of the car to look it up in our coupler conversion list; we can’t identify cars if you don’t know the make and model of a car. You must research it online, ask a railroad forum, or visit a railroad club or local hobby store. Then look it up in the coupler conversion list. https://www.kadee.com/convpl
