Acronyms

When I first started getting involved with the Carriage and Wagon Department, I was consistently fooled by all the acronyms being banded about. So to help others, here is a small list of acronyms used to describe coaching stock and also some "accessories" found on these vehicles. As most of these were thought up before the term "Standard Class" was invented, I use the term "second" for the "S" letter.
