Can Lionel PW 022 Switches be connected to LED's

Assuming you can mount the LED in the housing. Electrically speaking assuming up to 18vac input install a 1n4001 diode (in proper polarity) and 1k resistor, 1/4 watt resistor in series to the common lead.

See http://www.trainfacts.com/trainfacts/?p=360 for a look at my control panel with bicolor LEDs for the switch indicators and momentary toggle switches for the controls.

The circuit consists of the switch, T-1 bicolor LED, 2 diodes and a resistor. 

The above parts attach directly to the switch terminals.

Thank you both.  By my understanding then, I should be able to hook things up per my drawing.  If this isn't correct, please let me know how I should change it.

Looks good to me as long as your bi-color LED is a common cathode model.

should work. John can he just use 1 diode in the middle?

I wouldn't do that, as the possibly of a current path between the two unprotected legs may zap the LED.  I was actually thinking of two separate LED's for this application, no possible issue of the off side affecting things.

Thanks a lot guys.  The LED is the common cathode type so no worries there.  I had never used diodes before so I wasn't sure of their use.  I'll just pick up a couple at Radio Shack locally, and then place a larger order from one of the electronics stores on the internet where they will be cheaper.  I liked the idea of one LED instead of the two.

One LED is great - unless you are red/green colorblind.  That is one reason you won't see single-bicolor-LED traffic signals.
