QUOTE: Originally posted by cacole Track power cannot be used for turnouts because it is not on all the time, or is too weak to throw the turnout if the train is not running fast. You need a constant voltage source for the turnouts. I'm not familiar with Lionel turnouts, but most require at least 12 Volts AC or DC, and power packs for HO scale usually have 16 Volt AC or DC constant voltage terminals for turnouts and lighting uses. If the transformer you're using has terminals marked as "fixed" or "constant" voltage, use these for the turnouts.
