I'd have to agree with Tankist, Dream. You'll learn more, faster here. My son got me a subscription to a magazine for Christmas---Classic Toy Trains, a good magazine. However, think about what you're getting---it's a group of people who have to come up with something new, every month, to write an article about. After a while, they get stale and the articles reflect it. They also sound like spokesmen for the manufacturers who advertise in their magazines---big surprise there, huh? It's sort of like "...and this is the engine or car you just HAVE to buy this month, or you're a loser!"
Try this, instead: go to the library and do some reading. On top of that, ask questions and poke around the internet. Look at some sites to help beginners sort it out; maybe start with these:
They're free and you'll learn a lot. Pick an HO manufacturer and look at their on-line catalogs. Go here and download a very nice demo for laying out your track, for free:
Finally, don't downgrade yourself. Last October, I had a train in a box in the attic that I knew nothing about---someone gave it to me when I was a kid. I knew nothing about model railroading, and I assure you Tankist will tell you that's still the case. *L* The point is, you'll learn the stuff by asking questions and reading what's talked about. Don't feel intimidated---when someone uses a term you don't understand, jump in and ask what it means. These are good people and they want to help you get up to speed.
