I did a search and found another thread that talked about it but there wasn't much in the way of details. This seems like it can be done but I was wondering if there's a kit available somewhere or is this something that I'll have to make myself. I'm thinking of adding a decapod to help our mikado pull a grade and would like to be able to double-head the two. The problem is mth uses a fake plastic coupler.

I know in the Decapod Premiers MTH includes a standard non operating front coupler and all you have to do is remove a screw to switch it with the one that comes on the unit. This way it is easy to double head them. Maybe you could just purchase one of those couplers from MTH and figure how to mount it on your Railking engine. An operating electro coupler would be quite a mod.
Here are some pictures.
For the 2-8-0 all I did was dremel off the falsey, and file a flat spot for the mounting pad for the dummy.


Then I carefully marked and drilled and tapped the screw hole. I used flat black paint to cover all the shiny casting spots.


Here are the two 2-8-0's lashed up and ready to roll. I have kept them as a lashup ever since. The most critical thing is the height of the new coupler mounting pad. It worked great on the 2-8-0 once I removed the falsey, and I think yours would be similar.
The fixed coupler is a standard MTH part and comes with the mounting screw.


Hope that helps,

I recall that when I bought this loco the "scale" coupler was on the loco but later was damaged. I don't have the other coupler. The front receiver for the couplers was damaged and is missing a portion to allow me to put any coupler in that small box. So I have to consider a plan B or just leave it but I would like to use it in switching manuvers. Thanks.
One other option is to use a Kadee. I unscrewed the coupler that came with this engine and used a modified 806 Kadee. I epoxied it into the pilot. It works great. Kadee couplers work with traditional 3 rail couplers even though they are more scale sized.

This picture was taken before I epoxied it and the coupler is not canted up as it looks in the picture.

I looked on the MTH website but was unable to find the part number that way. So, I called MTH and got a voice mail from Midge. She called me back today and I ordered two. The next challenge will be dremeling out a portion of the pilot and deciding what size drill bit to use for the mounting screw hole. Thanks for your help. I will post photos of my progress if anyone is interested.
Here's my Ralilking 2-8-0 with the short shank Kadee coupler and pocket:



and my Railking Imperial 0-6-0 with same:



Seems like all I had to do was get the front area flat and smooth and maybe added a shim to get it down to the correct height on the gauge. It sure wasn't something you need a degree in engineering to do.

BE WARNED...Once you stick a Kadee on there you'll soon be buying them in bulk to convert the rest of your fleet!!! (I know I did)
I received the MTH coupler a couple of days ago and completed the installation on my Lionel consolidation. It was my first time modifying anything on a loco. It was a challenge to cut out the broken housing, enlarge the space to allow the coupler to move to either side of center when on a curve. I used a drill as well to do some cuts and a file to even out some of the cuts. I shimmed the coupler so it was aligned with the couplers on my rolling stock. It was not a difficult project, but the metal on the loco was incredibly tough. The coupler works well so now I can use both ends of the the PRR consolidation for switching as I had before the coupler housing was damaged. Thanks for the advice.

I had to buy new Dremel bits prior to modifying my locos. Seemed like a file did a pretty good job though, except it took longer. I used the Dremel to remove the majority of the metal then the file to square things up. I guess the "right" tool would have been a milling machine, but they're a little expensive for onesies and twosies type jobs.
