I am just getting back into railroading, and am wondering which starter set would be the best to begin with?  Eventually, I want to end up with a layout on a 8' x 8' platform.
It will take me time to build this, both in scenery and in operational fixtures.  I keep reading about DC, DCC, etc., but have no idea where to start.  Can anybody suggest something for me?  Thank you in advance!  (PS, am a 62 years old beginner)
