I currently have about 140' of track that is connected with rail clamps. They work good but the price adds up quickly. I'm looking at expanding in the spring/summer to triple the size of my layout. I've seen where some solder wires to connect track instead of using rail clamps but I was thinking of just soldering the track together. Anyone try this? Seems like it would be easy enough with a plumbers torch a little flux and some low temperature solder?
