I am using (N scale) T-TRak modules as bases for my HOn30 layout. Normally Unitrack provides the mechanical and electrical connection. As I am NOT using Unitrack, I am lacking a way to join my modules. A fellow HOn30/HOe modeler in Germany used "banana" type plugs. They work wonderfully in making a solid joint and excellent electrical pass through. But those do not seem to be available here in the USA, and are not exactly inexpensive to buy and then get shipped here. So, I am searching for ideas. They must be easy to find, and not break the bank account. Anyone have a thought or two on this subject???
