BTW, I just bought some "suitcase connectors", I was not aware Fry's Electronics sold them but most Electronics stores I visited called them "T-Tap" connectors for the T-Connection type OR "In-Line connectors" for the single line conversion type where you shift from one wire gauge to another. I just bought the 14 guage to 16 guage T-Tap connectors and will use either terminal blocks or solder for the feeder wires.
Model Railroader has a video on youtube somewhere where the guy recommends piano wire for feeder wires and then he takes a pliers and shapes them like track spikes and uses a real small drill to drill the hole through where a track spike would be on a RR tie. I thought that was an interesting approach but he never said what size piano wire. Is there only one size? Beats me and how he solders such a small wire to the rail without melting the tie would be a neat trick unless he just drives it in like a spike......he didn't say in the video.
