Changing Snap-In Rapido Couplers to Knuckle Couplers

Graeme operates N scale and his question to readers is:

“Hi guys i recently bought a few Fleischmann carriages with snap in Rapido couplers, I would like to change them to snap in knuckle couplers. I found some but don’t really want to pay $100 for 5 couplers that includes post from England to Australia, I think that’s a bit over the top. Any ideas?”

    Hi, Graeme. I’m afraid I have no idea how you can get knuckle couplers cheaply, but when you have some, you don’t necessarily have to have one at each end of every vehicle – you can economise by having just one at each end of a fixed rake of, say, 3 or 5 vehicles and keeping the Rapido couplers in the intermediate positions within each rake. The length of each rake will depend on your operational needs and financial resources.

      Hi Sheldon thanks for your advice, the thing is money is not a problem, I just can’t get my head around shelling out $20 for a cents worth of plastic.

    1. Why are they so expensive? 2. If you are going to couple and uncouple a lot, they are worth it. If it is only for cosmetics, then one at each end of train should look good.

Use Tiny Railroad Micro Controllers

A micro controller is basically a small programmable computer device to help the model railroader “make things operate.” It is clever way to realistically replicate the movements, actions and functions you are likely to see on a full size railroad.

It’s YOUR Railroad!

Your rolling stock and locomotives might actually be the center of attention on your layout, but the scenic features that surround and envelop your layout is what's likely to make your train setup stand proud of the rest. Your selection of scenery and structures will add an element of customization that will make your railroad truly unique.

Scenery, structures, and fine detailing is a fundamental aspect of any good model railroad, particularly if it is intended to replicate a true-to-life railroading scene. How realistic or authentic you make your railroad is entirely up to you... and you alone.

Some enthusiasts like to replicate every tiny detail so as to accurately depict, in every aspect, a miniaturized version of a real life scene.

Others in this hobby adopt a more "free-style" approach and choose to mix and match accessories and features they personally prefer. Even though the purist will possibly be unimpressed with unrealistic or out of context elements, it is YOUR railroad layout so you can make it anything you personally want!
