Lionel 022 switch wiring question

You can daisy chain the voltage pin. So you don't have to run a separate wire to every switch from the power source, although it would be good practice. The center pin of the switch is also "ground" (outside rail). So you probably can eliminate that wire to the 022 switch and just connect the center pin of the momentary toggle switches to the ground.

You don't need the common, center binding post connection from the switch to the SPDT. Instead, use a common connection near the SPDT switches at the control panel for the center connection of each SPDT, and daisy chain them(you don't have to make home-runs from each DPDT). This will reduce your wiring from about 20 wires(one to each switch) to one.

Now, what you can do, is to use each now open center binding post connection and make a connection to your common bus as the bus travels around the layout.

For the fixed voltage plugs, if you instead use coaxial barrel plugs, you can make your switch power fixed voltage connections to the tip and your track power connection(s) to the sleeve. This will improve continuity throughout the layout and cut down on obvious power connections like soldering and lockons. You can make similar connections at UCS & RCS binding posts as well.

I would follow Rob's & Cjack's suggestion and not run the center wire between toggles and switch motors.  I would also run a hot lead around the layout to feed the fixed voltage plugs from an accessory transformer outlet.  Avoid using track power to control switches.

Thank you very much for your reply. I will do what you say and appreciate all your help.

Much thanks,

wirring is qite easy once you get the hang of it

Kinda fun doing it but I hope it works. I completely wired a 1967 Corvette and everything work great from the get go.
