Give the kid a break. Yes he could easily look a lot of this up but he's excited about trains and Amtrak. There's not a lot of eighteen year olds as excited about trains as him.
Exactly! I'm really fascinated with trains! Ever since I was an infant! I'm so fascinated with them, that I like to do research about them! As a matter of fact, I plan to work in the railroading industry someday! And I'm trying to learn about some stuff about Amtrak from other experts on this website!
Just a word of gentle advice ... One very good way to carry on the research that you mention (as something that you like to do) is to get in the habit of first googling (or binging or whatever) the term or thing that puzzles you and see what comes up. Afterall, many of us who are answering your questions are doing exactly that. iI is not like we have everything sitting in our head ready to be poured out at a moment's notice or anything like that.
BTW CSXfoamer, since you like EMD diesels, I posted something that may be of interest to you. Take a look at
