I am trying to understand the chronology of what's been happening for the last 30+ years in this land of toy choo-choos. Lionel was in the MPC days when I was last paying attention 
Now I'm returning to the hobby and the different generations/series - the PostWar Celebration, Century Edition, Conventional Classic, Limited Series, and I'm sure I left a few out - etcetera. Some of them look just the same and understanding the plusses and/or minuses of them would help me out.
I'm puzzled about who came first in the years gone past, AND which series has more or less appeal or features/improvements and stuff like that. I have searched the forum and read several threads looking for maybe a list or something of the sort, trying to get the data crammed into my thick skull. Some of it makes sense, but maybe my old brain doesn't learn so easy now that I'm closer to 60 than 50. 
Anybody have a list or history/chronology of what happened? or a "cheat-sheet"?
