Reverse loop switch power

Bob:

I did something similar on my layout and just run them off track power.  You may want to extend the automatic detailing feature on the straight routes by adding insulated track sections, however.

I had a few engines that weren't throwing the switches quite quick enough and the insulated track sections proved to be a good solution.

If you're running a command system (constant 18V or so on the rails), there should be enough power to reliably throw the switch. However, you might introduce some voltage spikes to the running rails that way, so installing some form of transient voltage suppression would be appropriate.

 

If you're running conventional where the track voltage could be a lot less, you might not have enough power to kick the points all the way over. Then, you'll need to run accessory power to the switches.

What switches will you be using?  I ask because LIONEL's PW service manual specifies testing the 022 switch at 14-16 volts.  As previously mentioned, running conventionally relying on track power may not supply adequate voltage for this particular switch.

I'll be running all Lionel; O22, O42 and O72.   Looks like separate power will be the choice. Is the track pin arrangement different for switches powered separately?  

No, track pins stay.
