Plastic couplers

Post by Dale_F » Thu Jun 01, 2017 4:18 pm

I know that a whole bunch of plastic couplers were sold at the Train Mountain Triennial in 2015. They have been out there now for 2 years. I have no stake in this company, but am just wondering how they have held up for people. I have had a set on 2 of my cars and so far have not had any problems at all.

I am looking to hear from people who bought them and have used them. I am looking to learn if any have failed, or if anyone feels they are unsafe. I want to move the couplers to more of my cars but just want to do due diligence. Unless you have a pair in your hands, I am not really looking for your opinions.

Thanks.

I put one on my stock car. I use it for a propane car, so it is the first coupler behind the loco. I pull 8 cars, sometimes more. The coupler has never failed.

This topic just came up at our local club (Annetta Valley & Western RR). My friend Terry wrote the following:
I bought a pair of these just to see how they would do. They couple with almost everything we have at the track, but I did find a couple of older couplers that they did not mate with. With those, I could not get the plastic knuckles to close far enough to lock. They DO seem to be strong enough to include in a fairly lengthy train. Overall, I'd recommend them.
Hope this helps.

Plastic coupler between tender and propane carrying car? You're welcome to use that coupler as you see fit, but that wouldn't be my first choice for a plastic coupler application. Sorry. Even if equipped with safety chains...would prefer (and some clubs require) some kind of metal draw bar...either steel bar stock or a cast iron drawbar coupler. Just another $.02. Carl B.

Hmmm. If you'd have mentioned ductile iron, I might agree, but (gray) cast iron is not known for its tensile strength, and may offer a similar risk of failure as would plastic.

Harold...have to admit, don't know what material the coupler draw bar was cast in. It was a commercially available product that I've been running between the tender and fuel car for 16 years. Still, I have a pair of safety chains between the two pieces of rolling stock. If nothing else, the chains help keep the fuel and air brake lines from hanging too low (although those were cut to prevent dragging). Carl B.

Tom Bee and Dennis Goodman both produce dummy coupler drawbars in very high quality ductile iron. They will never break. I wonder how the the plastic couplers compare to the old cast aluminum couplers popular in the early days of the hobby. Knuckles breaking in derailments are always the big problem in the cast aluminum and also the grey iron
couplers.

I've not had any luck locating the plastic couplers. Can anyone point me in the direction of a commercial source?

Thanks

Thanks Marty. I tried to email them but it bounced. I guess a phone call is in order.

I have found that Bachman plastic couplers while being too small for 1-1/2 scale are just the right size for 3/4 scale and oversize for 3/8 and G scales.

Ron, do you mean their G scale couplers, or their 1:20.3?

Very interesting, as I build narrow gauge on in 1 3/4" scale on 3 1/2" gauge.

Thanks!
