Type E Coupler for LEGO Trains

Recommended Posts

Figuring that the modern Lego magnets are $2-$3 per pair, the old "choke yourself" ones probably > $5 a pair, and Kadee about $5 a pair the target price seems viable. Even though I am too invested in magnets to switch I could see building specific train sets with the new coupler system (e.g., a unit train or a new passenger train).

I would be interested in this for sure. 

I think that there are too many purists to have wide adoption but for all of us north american modelers, these would be awesome and I could sell my magnets to fund the purchase of these haha.

I'm definitely interested if this goes ahead, something I've been on the look out for in one form or another for a while now!

Best of luck with the design!

Just for an idea of what I'd purchase, I'd be looking at c.10-12 packs of 2 couplers, so if you did some kind of multi/bulk pack I'd probably get that to start with! Would the idea be for a kickstarter? Because I'd pledge at least $50 to help get this to a reality!

I'd be interested in any coupler system that allowed remote uncoupling so realistic yard activities were possible. I doubt I'd want to change my whole fleet over but perhaps all my engines and freight; 20-30 pairs. If they were in the ballpark of the current prices for LEGO couplers that would be fine. BTW I model German trains so if they fit the old buffers as a replacement for the magnet that would suit me best.

I agree with peterab. Have several hundred of cars, so change of the whole fleet is impossible due to costs, but two or three dozens would be perfect for railyard-playing.

So (remote controlled/automated) decoupling- function is the part that makes this interesting for me.

About quantities: I, of course, would like to order bigger quantities at once. But due to customs in europe, it might be better to stay below excepted value. Maybe a bulk-offer should consider this?

Just a hint: I once ordered from 4D-Brix, and that was very comfortable since they run a european BL-Shop also. So from an european AFOL´s point of view, a Shop in europe or some kind of joint-venture would be very welcome... allready the same with your tracks....

When I was running the new trains in the office today I noticed how the new couplers have studs on the top and bottom. So could you not just clip a 1x2 plate there and you'd be done? No more issues with long trains decoupling.

Works like a charm for long trains, and especially nice at shows where kids tend to want to put their hand on the train:angry:

For coupling-uncoupling at a yard this does not work.

I find that for most of my needs, the Lego magnets function well. I would try these if they are produced. Thanks for sharing Coaster!

@zephyr1934, here is the video as promised:   26797003709_e3b0916f99_z.jpgKadee Coupler "Bump Test" by Sal Ciofani, on Flickr.  I think it qualifies as bumpy enough, haha.  As you can see, the Kadee couplers don't have too much problem with elevation changes, as long as it is not too severe.  @coaster, it looks like your coupler design is slightly bigger vertically than the Kadee couplers, I think this will make yours more forgiving of uneven track.  

One issue with your design might be, the opposing coupler might trip the uncoupling lever of the coupler it is hooked to on very bumpy track.   As far as centering issues, I had a thought, if you use a friction technic pin design, that would make it so the coupler would not swivel too freely, there may not need to be any centering spring.  I would be interested to test your prototypes when you have some ready, if you would like.

I have run LEGO magnets and Kadee couplers in the same train.  since both mount to 3176 I simply swap out 3176's with whichever coupler I need already attached.

If you add a second pin (or hole) behind the first one, you could attach one of these: 32017.gif

This would enable those who want to attach the couplers to bogies to do so, which would center them automatically. For those who body mount their couplers, you could simply just mount the coupler to the body using one of the pins/holes so that it swivels, and then use rubber bands looped around the free pin and attached to connection points on either side underneath the train car if you want it centered.

Edit: I'm also a fan of the friction pin and/or magnets. Whatever works.
