I am working on the Railroad…..

As the song goes, I am at long last laying track. No I don't know what I'm doing, but that never stopped me before. One tries and tries again, until you get it right. So no matter what, now is the beginning, and where it stops is anyone's guess. lol.
  I just hope I can understand what is written in the books and articles I have for reference.
I'll post pictures in a day or two.
