My coupler investigations continue…
Here are a couple of quick photos to compare the Kadee #5 HO coupler to the Sergent EC64 S scale coupler (actually, one I built years ago from the original production, because all of my current EC64 couplers are mounted on equipment). In both photos, the Kadee is on the left:
As the photos show, the couplers are very close in size. The EC64 is obviously more prototypical in appearance – that is, after all, one of the selling points of the Sergent line. But if we assume the Sergent EC64 is scale sized, then it’s clear the Kadee #5 is much closer to S scale than is the Kadee 808.
The Kadee #5 is not as tall as a Sergent EC64, either. But if I’m willing to overlook the giant spring on the side of the coupler (and I am), I can live with the discrepancy in height – especially if it means trouble-free operation. (As for that spring, I’ll tone it down with some Neo-Lube.)
I have also compared the coupler boxes for an HO Kadee #5 (Kadee #232) to the couplers boxes for an S scale Kadee #808. While I did not take pictures, I know that the boxes have differences which prevent 808s from being put into a Kadee 5 box, and vice versa.
However, in two key factors they appear to be identical.
– The distance from front face of the box to the post appears to be the same.
– The spacing of the mounting holes appears to be the same.
I will have to confirm this by mounting a #232 box to an S scale car. But in theory, I should be able to use Kadee #232 boxes (and the couplers in the 5, 20 and 40 ranges) on S scale equipment without having to modify my existing mounting procedures. That should save a whole lot of time and aggravation should I decide to change over the fleet to the Kadee #5.
Stay tuned for more on this in future posts.
(On a housekeeping note, if you’ve been following these posts using the Category link, I’ve changed the category’s name to simply “Couplers“. The link remains the same.)
