Disconnects. Up until I seen that magazine, I had never heard of a Disconnect But once I looked through it, I did a little more searching for various types and styles of disconnects.
Then I thought about their uses and versitile they really are.
Say for example you have three or four sets of these disconnects. Now I make a couple of gondola bodies, a couple of flat car bodies, a couple of riding car bodies. Each one of those bodies is able to plug into a king pin receiver in the center of the disconnect. Now you have the flexibility of all those bodies but the reduced cost of only three or four sets of trucks. Makes it easier to transport and store when not in use. Now this may not appeal to some but the configuration of the truck design is easily changed to whatever style you like. It's the idea of having fewer trucks to maintain. And since this is a project in process, I do plan on putting on some form of braking system.
