I highly recommend Larry Puckett's excellent book, Wiring Your Model Railroad. Larry covers reversing sections in some detail in his book, along with most other conceivable wiring situations. His book is available new or used, and is well worth the few bucks it costs.
His most practical approach to reversing sections: make the reversing track longer than your longest train, double isolate it on each end, and power it with a reliable type auto-reverser, such as a dual Frog Juicer or similar.
starman How to identify them
Paint one side of a boxcar white the other black. If on the same piece of track you see the white side one time and black the other, you have a reversing loop.
Colors and type of rolling stock is optional. If you only have rivet counter rolling stock, use a piece of blue painters tape.

Have you checked out Allan Gartner's Wiring for DCC Website? There's lots of great info there. As to the fact that you're using Digitrax, I don't think it really matters what your system is. From a wiring standpoint, DCC wiring is DCC wiring.

I am building an HO layout and using Digitrax as my train control. Can someone lead me to a good tutorial about reversing loops? How to identify them and how and where to add electronics that will control them. Thanks
