Step 1 might be to create some "transition" cars. Change some to knuckle couplers on one end only, leaving the other end horn-hook. It will be a little pesky for a while, because you'll need to use one of these cars between strings of knuckle-coupler-equipped cars and older cars, but it will allow you to run both in trains and to use newer cars behind engines still equipped with horn-hooks. Then once you've covnerted or upgraded everythign, you can go back and complete the conversion on the transition cars.

Creating transition cabooses is also a good idea ... horn hook on one end, knuckle on the other. Then they can be on the end of any train.

Edit: I see RLundy posted the same idea while I was typing.

rlundy90-I just cut the truck mounted coupler pocket off and use a body mounted draft gear box. You usually run into more trouble trying to get an after market truck to fit and work properly on the cheap cars. I'm all for changing the wheel sets, but I found changing trucks was more of a pain than it was worth.My 2 cents [2c]

Change em to knuckles, but in the meantime you can make a tranistional  car with 1 knuckle and 1 horn hook coupler. Then you can run old stuff with new until you get them all changed over. Kadee are the easiest to obtain and are a reasonable price for knuckle couplers. Sargeant are more to scale but they do not mate with the other makes of knuckle couplers and have to be uncoupled by hand. Also more expensive. If you have a bunch of old Bachmann stuff you may want to change trucks as well. Their couplers are truck mounted and may be a real pain to change.

WRONG!!! Nothing wrong with converting your old stuff over to Kadee's. It's NOT difficult and only costs about $1/per car/loco.

This site will probably answer most of the questions that you WILL have once you start converting to the Kadee's.

Well you can sell the old stuff on eBay and use the money to upgrade.

Unfortunately, the cheap stuff is the hardest to convert to knuckles. Go to a train show, you'll be surprized how inexpensive cars with knuckles already on them can be--especially if you shop for used ones.

Use your eBay money.

Don't try to save a few dollars. If you are going to the trouble of replacing couplers use the best..Kadee.  Only a few cents more thah the others.  Jerry

How old is "fairly old?"  And again, who made the cars?

My stuff had been in boxes for 40 years.  I found that Athearn cars, even very old ones, could be updated by simply removing the cover to the coupler pocket, replacing the horn-hook with a Kadee #5, and replacing the cover.  The rest, though, require some degree of effort and ingenuity.  On a lot of them, I end up completely removing the old coupler pocket and replacing it with a Kadee "Draft Gear Box," which is the more appropriate term for "coupler pocket."

A lot of old-time stuff had the couplers mounted on the trucks, rather than on the car body.  This presents a problem, because this configuration doesn't work very well either with horn-hooks or with knuckles.  In particular, it's hard to back up a train with these things.  So, you will likely want to "body-mount" the new couplers (and the draft gear box) after removing the old coupler assembly from the trucks.

Long cars, like passenger cars, will not work well with body-mount couplers if you have tight curves.  For these, I've left the couplers truck-mounted, and just replaced the boxes and couplers.

Old engines probably aren't worth the effort.  New engines are just so much better, in every way.

Sorry, not really. IT is worth the effort though. You can get 20 packs of Kadee #5's that will work in most applications. Then it's a matter of looking specifically at each engine and car for the right one.

Unless your rolling stock is really high quality, if the change over to knuckles is difficult, it might be worth your time and money to buy newer cars to replace those cars instead of converting them. I'm referreing to the cheap Tycos, Life Likes, and Bachmann's.

Hmmmm.... I doubt it. you might be able to stick them to the knuckle couplers if you tried hard enough but I think you'd just end up with broken couplers. I had this problem on my small n scale layout.

No unfortunately they won't. Horn hook couplers are very seldom seen anymore. I think some new models come with them in the package but almost everything comes with some brand of knuckle couplers factory installed. What you can do while you are changing couplers is have a car that has one knuckle and one horn hook coupler so that you can run trains with cars that have either type of coupler on them.

Horn hook vs knuckle couplers
Posted by 47gotcha on Friday, November 2, 2007 9:05 AM

I've been out of the hobby for several years due to moving to several new homes since my last model railroad build.  All of my boxed up equipment is fairly old and it all has horn hook couplers.  I intend to eventually convert over to knuckle couplers, but it may be awhile.  I am also eyeing some newer motive power and rolling stock, most of which now comes with knuckle couplers.  My question is;  Will knuckle couplers mate up with the horn hook couplers of my existing equipment?
