I am new to rail modeling and wondered about using uncouplers in sidings and other areas of track. I have a couple of questions:
1. will the train uncouple every wagon/ coach that rides over it.
2. can it be set so that it will not uncouple.
3. more importantly can I make this work electrically.
I appreciate any help and assistance.

Thanks.

Hi Del,
Welcome to the forum,
The peco uncoupler you mention i have seen used in layout as to how effective they are i'm not sure used via a small metal strip curved around a penny i believe and glued to the coupling underside, when passed over the magnet each wagon in theory should be able to be seperated from a rake individually how reliable it is i cannot guarentee, PL -25 is the electro version they make.

Dependant on scale and type of stock a more reliable way of uncoupling are Kadee (00)/ microtrains (N) though as has been covered in other areas of the forum conversion of British stock to either of the above needs significant modification .

I tried to upload this image last night but couldnt find it on the net


shows you the uncoupler installed, and a metal tab attached to a coupling.

Thanks for the intro. Could you explain the penny construction as I can't see the relevance?
Thanks

Hi Del,

Sorry i should had made myself plainer with the reference to the penny, i cant find the instruction illustration for it but the coupler lifter arm shown here installed on the coupler itself is formed round the edge of a penny giving the curve it requires.

Click here to see what i mean in the circled underside of the wagon end.

the arms themselves come flat as here.

I have seen them on N gauge stock and as far as i am aware they are available in OO

If I am reading you correctly this would mean changing all the convential coulings, this would be quite a task with a lot of rolling stock.

I am looking at thee solinoid assy. Am I correct in think that the solinoid moves a pin up throught he base board into free air and when the coupling passes over head the curved piece lifts up and uncouples?
Thanks

Hi Del,

The uncoupler works via an electro magnet powered through the pin and attracts the metal curved piece as on the S.R. wagon in the illustration, thus lifting the wagon coupling up and free from your other wagon then move the loco off with your detached wagon.
the couplings remain the same having the addition of the curved metal piece applied, the small plastic pin on your coupling now fits through the hole on the metal piece.
A word of caution it is not reccomended the uncoupler is used with Farish wagons or any containing a spring in the coupling.
