1984 Equipment Diagrams
While these are Chessie diagrams, they are accurate for the pre-merger equipment also.
The equipment diagrams came from a 1984 set, but many have dates in the mid 1970's.
They are listed by Chessie System classification.
For each Chessie class, WM class is indicated, as well as date of document.
Only equipment with WM reporting marks is included. All are available as .pdf files.
