Prototype Hand Brakes
Gene Green <willibecher@...>
Please help me compile a database of hand brakes used on freight cars
built between 1937 and 1960 inclusive. Column headings are listed
below. If anyone can contribute information I would be much
I have found the best source to be equipment diagrams although, in my
experience, the hand brake model designation is seldom included.
Construction dates of the car series helps because, to the extent
that a hand brake manufacturer had only one suitable model, one can
make a supposition about which hand brake might have been applied.
Before 1950 each hand brake manufacturer supplied a proprietary bell
crank or, much less often, a sheave wheel. Information on these bell
cranks, if available, would be listed under NOTES.
1958 was about the end of the malleable (cast) hand wheels unique to
each manufacturer. Hand wheel information, if available, would also
At present the database contains 299 car series. I would be happy to
make any information I have available to anyone with an interest.
Five items marked with an asterisk constitute the minimum data
acceptable for an entry.
QUANTITY (of cars in series)
SERIES* (number series)
TYPE (of freight car)
CAPACITY (nominal capacity of car)
BUILT* (year is sufficient but more precision is desirable)
LOT (number) or ORDER (number)
HAND BRAKE MANUFACTURER*
HAND BRAKE MODEL DESIGNATION
SOURCE* (of hand brake information)
REFERENCE (to hand brake manufacturers drawing)

Sounds like a very worthwhile project. I'm in, but I've already come up
with some questions...
First...For those of us so inclined to send a data file...What file
format would like people to use in order to minimize the effort for you
to incorporate it into the "larger" database? I'd assume that you'd
like a data record with the same number of fields.
Second...How would you like "rebuilt" cars handled? i.e. a car built
during 1937-1960, but rebuilt after its original build date? Obviously,
the car could have the original hand brakes, but that assumption may not
necessarily be valid. Would you like an entry in "Notes" about the
rebuild date that was known from the equipment diagram or other source?
Kind regards, Rob Adams

Good questions, Rob!
Most folks use Excel nowadays and I know I can open those with my
antiquated software although, just now, I've forgotten how I do it.
(For those who don't know I'm still mostly operating in MS-DOS 6.22.
Screw Windows) I really prefer a text file which would be adequate
or a comma delimited which is ideal.
Rebuildings: Cars built before Jan. 1, 1937 might not have a power
hand brake but, if rebuilt after Jan. 1, 1937, would be required to
have a power hand brake applied during rebuilding. In those
situations the date REbuilt would be substituted for date built.
For cars built after Jan. 1, 1937 and rebuilt Jan. 1, 1937 would, in
most cases, retain the same power hand brake because power hand brake
applications after Jan. 1, 1937 were "grandfathered in."
For situations I haven't anticipated, use the REMARKS column.
For Mike Brock: Do you want this handled off list? Or do you think
others might like to see the data as it comes in?
