Rocco,
Welcome to the forums. In the future, you will have more luck asking your questions in a new thread instead of resurecting a 12 year old thread. Usually if I see an ancient thread brougt back I don't bother reading it. Most times much of the info contained is obsolete.
Hello all,
If you go to the National Model Railroad Association web page, under the Education tab you will see the Beginner's Guide.
At the bottom of this page; after the disclaimer, you will see a link: Continue to the Beginner's Main Page.
From there you can choose any of the sub categories. These sub categories include explanations and diagrams of the subject matter.
You can also look under the Standards tab for Standards & Recommended Practices along with the DCC Section, which goes into technical information.
To my knowledge there is no single printed source of a dictionary or encyclopedia, the NMRA web page is probably the closest you will come.
That is not to say that there are many websites and books that have glossaries that cover many of the terms and concepts in model railroading.
Hope this helps.
