Many thanks!

Novice level - pretty new to model RR.  Question: we have an old Bachmann Hershey "Diesel" engine, which I assume is analog and are using a Railpower 1300 controller, which appears to be DC.  1 train set running on EZ track.  We were looking at setting up a double reverse loop (similar to "dogbone" layout, but with a main line connecting to loops via turnout switches.)  Question is: what is easiest way to make that double loop work.  Looked at Bachmann's auto reverse loop module, but that's DCC only, so would either have to convert analog to DCC and system to DCC - sounds time consuming and pretty expensive.  Is there another, easier way?  Would purchasing a DCC ready/capable engine solve it since just 1 train set running at this time?  Sorry if any of my lingo is off-still learning the very basic.  Any help is appreciated!! thank you!
