hi, i have an atlas turntable and plan to use 18 stalls -- i want to be able to power each stall separately since i will have a combo of lion chief, legacy and conventional engines

i'd like lighted switches so that i can see which stalls are powered

anyone have any recommendations -- easy solutions are good for me

i was considering these, any advice?  thanksmceclip0

A simple 18 or more contact rotary switch will work.  You will not need to operate more than one stall at a time.  More than 18 if you have external stalls adjacent to the 18 stall round house.  Hook up the rotary switch in series with the turn table track and in series with a momentary push button switch used when you want to move engines (push button switch shown black below).

Turntable construction is detailed in post on page one of the below topic.

For my turntable tracks, I used dtdp (double throw, double pole) switches. These switches have an up, down and center position. Up powers one track, down powers a second track and the center is off for both tracks. I only need one turntable track on at a time, the one where the engine is going to/from. No need for complicated electronics. So to power 8 tracks, I use four of these switches.

Switches, terminal strips and DC drive for the atlas turntable:

085

Wire connection schematic that is on the back of the panel, so I can see where all the wires should go. I then label all the wires, so they end up in the right place. I use colours that match the wire colours that I plan on using. In this case, all of the wires are either red for track power and black for ground.

088

The front of the panel, with 8 powered tracks, and one switch to turn the Atlas turntable clockwise, counter clockwise, or off (center position of the switch)

092

Design schematic for the wiring. I did this using an Excel spreadsheet, sizing things correctly for the size of the switches and terminal strips. It may take a few tries to get the sizing right. This allows you to have clear label names, so the wires get connected to the right place.

076

The labels on the front show the track number (T!, etc) inside a CP logo. You can do the same using a version of the logo for any railroad. The same label is then on the track, so you can easily see the number of each track. Using the railroad logo makes it look better on the layout.

However the electronic LED idea is cool and would work well.
