Are very reliable The problem is that they are at the moment very expensive 12-15 Euros I try to do something like with normal couplers and SIL pins If I succed I will post the method Thanks

The problem is that they are at the moment very expensive 12-15 Euros Really quite expensive, 15€ per single coupler, not a pair!!! A bit cheaper, You get them from http://www.lokmuseum.de for 9,40€ each, but still quite expensive.

Best regards Eduardo Of course can be used with analog AC trafo. The capacitor must be at least 63V. Of course the rectifier voltage must be high enough, usally the rectifier bridges are 200V or more. Costas

They are very flat, and they won't touch the rails or get stuck at turnouts. They are not new, though. AFAIK they were introduced as standard in a Märklin DB train set with a control car (I don't remember which one) about 15 years ago, and have been available as spare parts since. I bought some in 2005 for €3.20 each. Recently, prices were increased to €12 ea, as happened with most spare parts.

Dereck Would not one of the plugs then have, say +ve on the male and -ve on the female, and the opposite wagon's plug would need +ve on the female and -ve on he male.. so that the cars still could not get flipped around in orientation? You'd get short circuits that way.

Joined: 05/12/2004(UTC) Posts: 2,973 Location: CA, USA		Hi all, Some research led me to this post, which I find interesting for my project I'm working on. A question for experts familiar with this: a single coach per the diagram/ video in this thread makes total sense to me. But to extend it to a 4-6 car train, pretending 2 pole couplings or similar, does the circuit change, or do I just run the LED strips from car to car and thats it? I'm assuming the draw of the additional LEDs will mean at least a different resistor, or a pot to adjust?). And do you cut the strips as well as reverse the +/- in every car, or just the "lead" car? Thanks for any advice! This seems like a cheap solution, and additional cars would only cost the extra bit of LED roll and the 2 pole couplers/wires?

Thanks for any advice! This seems like a cheap solution, and additional cars would only cost the extra bit of LED roll and the 2 pole couplers/wires? The experts will chime in but here is my quick take. The ground comes from wheel pickups in each car so you only need couplers to conduct the track voltage from the center pickup - 1 conductor or are Märklin conducting couplers. In each car you do it the same way - a rectifier and capacitor and resistor to feed a local strip of leds. That way you can rearrange the cars at will.

This is how I do it: One ground connector per car One rectifier per car One resistor per car One capacitor per car One pickup shoe per train One function decoder per train One relay per train Current conducting couplers It’s explained in the link above.

What I'm not understanding is any amendments needed for multiple cars on 1 "lead" car with ground spring/pickup shoe/rectifier/cap. I'm assuming that would be different resistors? There is also the potential for a capacitor inrush issue if using multiple sets, but that I know how to solve. Any ideas?

There are resistors in each car (along with a rectifier and a capacitor. The layout is divided up among three boosters so maybe that helps with in-rush. Regards, Roger

Regards, Roger Hi Roger, just curious are you using a ground spring in each car, or one master and running two pole wiring from car to car? If the latter, how are you handling the connections/couplings between cars?

Joined: 19/08/2008(UTC) Posts: 1,041		Hi John, I use a ground spring in each car. Couplings are one pole either the "permanent" or couplable(?) 72020. I generally couple two cars together with the permanent one but have the 72020 on the two ends. Some pairs have a slider others don't. I have found that a 3 car set coupled "permanently" are difficult to handle when rerailing. Most my passenger trins are 6 cars or more so there can sometimes be more than one slider but I do prefer one because of the drag. I also apply powdered graphite to the axles where the ground sping makes contact to reduce drag. Regards, Roger

Joined: 04/02/2021(UTC) Posts: 477 Location: USA		Some pics of LED strips with small capacitor and conducting couplers for plastic cars (connect front&back couplers with its own wire, instead of rectified LED strip power). Metal cars cannot be connected through the coupler (which is ground), so I use a thin single wire with electronics board connectors between cars (LED grounded in each car). Obviously, disconnecting metal carriages requires manually unplugging wire.
