Irish, <br /> <br />The real savings in wires comes when you compare standard DC layouts wired for multiple cabs and blocks. The cabs require rotary selectors for each block as well as direction toggles etc.....The number of wires is staggering when you have a system using say, four cabs. One guy I know still uses this system and must have spent years wiring it all up. DCC doesn't need to worry about cabs and the ever famous line, "who has my block" may slowly fade into history??? Check out cab control in standard DC and you will see what I mean.
