Marx Couplers
 
Notes Index
 
  Most common couplers on Marx equipment was the standard NMRA X2F horn hook couplers. These were mounted on a tab that was connected to the trucks and swiveled with the truck. They were not actually mounted to the trucks as the tab slipped over the pin in the bolster and had tabs that locked into the topside slots of the truck.  

Shows the overall apperance of the standard Marx truck. The slots in the bolster are where the tabs from the coupler pads would fit.

The coupler mounting pads came in two sizes. The long top one was used on the cabooses. The short bottom one was used on most cars.

The coupler was assembled using the coupler mounting pad, the bronze coupler spring and the coupler. This had to be assembled over the mounting pin but through the coupler slot on the car. The trick was to insert the coupler through the coupler slot on the car, then slid the prongs on the coupler pad through the coupler slot while lining up the hole in the coupler with the pin on the coupler slot and getting the tab on the spring to be on the side of the coupler. This takes a little practice and a lot of patience. The truck was then snapped on over the mounting pin.

The battery operated sets had large, non-working knuckle couplers. The cars had to be lifted up and the couplers slid together and then set back down on the track.

This photo shows how the couplers are attached. These couplers are attached the same as the horn-hook except that they do not have the interlocking tabs so they swivel independent of the trucks.

  Another coupler system that Marx had is the loop and hook. I have not seen the Marx cars with this system, but photos by Bob Robb show them:

UPDATE:
Received an email from Steve Rademaker about these cars. The sets were made by Rosko and also licensed to Marx. The cars without markings are Rosko and Marx stamped theirs with the Marx logo.

Close-up of the truck and coupler. These trucks and couplers are riveted to the car, so they must be original equipment.

Close-up of the bottom of the truck. This does not look like it was something added by the modeller, this looks original. These trucks are not attached like the "normal" Marx pin. Unknown on how they come apart.

I have a bunch of cars that have this truck and coupler combination. These cars are made in Japan and do not have the Marx logo on them. The bottom of the gondola is very plain without any details.
UPDATE: These are the cars produced by Rosko.

The box car just has Made In Japan on the bottom and the bottom is flat with no details at all.
