This site contains digitized copies of Chicago Burlington and Quincy
Railroad Class Diagrams. Class diagrams are schematic, non scale
drawings of equipment and include important dimensions and weights.
Ray Buhrmaster and Joe Douda have generously allowed their class
diagram books to be digitized and placed on the Web for non-commercial
use.
The images were scanned at 300 dpi, restored, and compressed. The
restoration attempted to retain as much as possible of the original
diagram consistent with their being line art. The originals are
unreadable
in some places and I have filled in data from other sources,
principally
Corbin and Kerka's book, Steam Locomotives of the Burlington Route
. "Comic sans serif" font was used to fill in data which was unreadable
on the originals and is clearly different from the original hand
lettering
without being a distraction. I have improved the cosmetics by removing
most dirt and stains, but I have not cleaned up edges. My object is to
make the information available, primarily to the modeling community.
The class diagrams are formatted as a single landscape "A" size page to
match current standards. The pages were assembled into a book
approximately
4" high by 11" wide using the hole punch marks. I have not retained the
margins used on the originals. Selecting the "Pixel to pixel" option
reached
from "Options" on the Wang Imaging "PRINT" screen will allow the
diagrams
to be printed full size on a 300 dpi printer. Engine numbers listed on
the links may not be valid, but they (or numbers they span) appear on
the
class diagram. - Vernon
