Welcome ChooChooPappa...
Starting fresh? Here are some postwar trains to drool over

Thor's train & toy soldier site (R.I.P. Thor; visit, it may vanish)
Olsen's Trains has a great parts site, but is down for a while.
Instersted in one you see? Start a thread and ask about opinions. Take everything in slowly as you can. Some folk manage to hang out a while before breaking ground, some will have a table up 4 days after the first post.
1. New track is great. Check Menards online prices and shop around. Check for review threads here in search. Pre war fat wheels make careful turnout a must. And speaking of fat wheels and tin, dont turn your nose up to quick on Marx, American Flyer O, or some of the others. 0-36 or larger if you can.
2. Don't get cheap on power. Not many folk cry "I bought too big". It's always I didn't buy big enough. 90w min. in a 1033, 125w LW, 180w KW, 180w VW, 250-280w ZWs, prewar R, S, V, Z 110-250w , A.Flyer 15b*, AF 18b*, and some Marx(not very servicable)
Buy refurbished with a warranty or read up on checking old for rebuildability, good windings, rollers, arms, etc. so you don't buy a dud because it lit one bulb or made someting run for 2 minutes.
3. Keep a carpet loop to run when bored if you start a huge layout. Some days you just want to run, not build.
4. Spend time running again asap and figure out for sure if you are still a looper or into operations before you build extravagantly either way. Heck there are collectors that never run anything or even have a track. Others like the scenery work more than running , etc... Know thyself. And before you say you do; your not a kid anymore; doublecheck
5. The for sale forum here is a pretty good place to begin. On "those auction sites" check the completed / sold adds to keep from overpaying.... A big price tag doesn't mean crap. I want to sell sticks of gum for $25 but who will buy.
6. Find a local club to visit. Ask if you can try something out in exchange for a small donation or something. There is new stuff to amaze you there. I want my old school stuff too, but you owe it to yourself to at least look.
7. TTOS, TCA, LCCA are clubs you might want to visit online... especially TCA grading guidelines since you are buying soon.(no price guide, just grades)
8. Don't run away if someone gets cranky some day
* these Flyers work best for non-whistle trains. They seem to trigger the whistle randomly, especially on new trains.
New trains and old trains, even items of the same brand are mostly compatible, but not always... always best to check.
