Long or Short shank couplers
Posted by COREY CHERIZARD on Tuesday, February 11, 2020 7:35 PM

I've searched the internet far and wide for an answer to my question, but have found nothing. So I turn to you, whoever's reading this.

I have an old Bachmann N Scale train set with the old Rapido couplers, I know that they need to be replaced with Microtrains couplers but I don't know whether they need to be long shank or short shank couplers.

Cory:  I don't know, I'm in HO.

Part of the answer will be what radius curves you use, part whether they are body or truck mounted, and the length of the cars.  More info will help more knowledgeable people than me help you.

I'm modeling in HO and had been running Kadee #5's as my default locomotive coupler until I started noticing locomotives uncoupling randomly. Upon closer examination, I noticed that the trip pins pressing against the snowplows of the adjacent locomotive, pressing the knuckle open. I replaced all of the couplers on locomotives with snowplows with longer shank couplers. Problem solved.

Microscale has converstion tables on thier site specifying which coupler to use.

I would try installing whichever couplers you normally use, like on your freight cars, on two of the passenger cars and see how they work. If you normally use shorter shank couplers and you find they don't give enough separation, you can try the longer ones.

FWIW on Walthers HO passenger cars, I find the best spacing is to use regular Kadee 5's on the rear of the car and long-shank no. 5's on the front. The regular no. 5's couple too close together (even for my 30"R curves) but using just long-shanks spacing the cars way too far apart. One of each works best for me.

what stix said. We have a club member that does exactly that and it works fine. He does have to orient the cars so a short matches up with a long.

I've been out of the N scale loop for many years but am collecting some N during the past year.  Pretty much everything I have bought has MT couplers already.

But why long vs. short?  Doesn't MT make medium shank couplers?

I use a paint marker-pen to make a little arrow facing forward on the bottom of each car so it's oriented correctly. It's pretty easy with a coach because the figures inside are all facing forward, but with cars where it's less obvious (baggage cars, diners, Pullmans with seats facing each other in sections) it makes it easier.

BTW I generally put a regular length scale-head Kadee on the rear coupler of my observation cars, as it looks better. That's also why I put the long-shank coupler on the front of each car, so the observation car coupler isn't sticking way out.

As I'm in N scale, I have purchased & installed short, medium & long shank couplers. Each car is different when on curves. I use 11 3/4 curves. I have put 1 long shank on one end & medium on the other end to maintain body clearance. Also consider body mount couplers. They can solve clearance issues on locos or rolling stock.

MTs 1019 coupler should work since its truck or body mount.

Which brings me to my Walthers subway set.  I put Kadee 158 scale couplers on them but the cars look too far apart.  I am thinking of going with short shank couplers on but am concerned that there will be derailments since subways operate on tight curves comp with other railroads.

I just added long couplers on my loco's since they were having difficulty navigating turns with the shorts on it.  It really all depends on the length of the loco and the degree of the radius you are running.  Speaking in HO terms which is what I am running you will never get an AC6600 to be able to pull any cars on it even with long shank if you are running an 18" radius curve.  Even thought the loco may be able to navigate that curve the ends stick out way to far to attach a car to it

Thats the big disadvantage such sharp curves as 18".  Just because they are sold in train sets doesn't mean they are a good idea.

Joe   Try one pair of short couplers.  Couple two cars with them and see how they work.  Don't do more than that until you know.

Thank you, I didn't realize that they had medium length couplers.

That sounds amazing, do you think you can send me the link? I seem to be having some trouble finding the conversion tables.

Corey:

     The Broadway Lion models NYC subways.  He uses drawbars, I do not know what length.  His reasoning is that a subway train is a unit, no switching.

Google the MTL website. In the search category put medium shank couplers. You can get assembled, unassembled, talgo style or body mount.

Yes I know the Lion uses drawbars but he has an extensive operation. I have one Walthers subway set that moves back and forth on display (Kinda a Staten Island thing one train that bisects the Island).  Drawbars are a bit much for my train.
