About Barber trucks: I have got a drawing of Erie
wooden trussrod boxcars in the 100000-101999 series
from the 1913 diagram book which notes the cars had
Barber trucks, but there is no illustration of them.
I'm sure they are not the same as Barber _stabilized_
trucks which Anthony mentioned (of which I have a
model photo; they are very distinctive, not to say
futuristic (jet-age) in appearance).
I am far from sure whether the ones in use in 1913 are
the Barber S2 design, which looks like a more-or-less
"generic" cast steel truck. Doesn't "S2" suggest it
wasn't the earliest design? Does the "S" stand for
"stabilized", which would put it circa 1930? If so,
what does the early Barber look like? Does anybody
have any light to throw on this question?
The Standard Car Truck Co. was founded in 1896 by John C. Barber, and
Standard has used the Barber name ever since (even down to the present
day) to identify all the various truck features to which it holds
patents. So the Barber name doesn't identify a particular design, but
any design or design feature developed by SCT. The Barber truck of
1913 bore no resemblance to the later Barber Stabilized designs that
first appeared in the 1930s.
BTW, other similar cars from the 1913 book have
Archbar or Fox trucks, but none seem to have had
Andrews trucks (although not every drawing has the
type of truck noted). Weren't Andrews trucks in use in
Andrews trucks of various types were extensively used by 1913.
I need to learn a lot more about trucks, or stop
obsessing so much :^) Maybe I'm also obsessing too
much about draft gear (what's the difference between
Miner Friction and Sessions Friction with Farlow
Though the information isn't of much use to modelers, draft gear design
is extensively described and illustrated in the various editions of the
Car Builders' Cyclopedias, if you can find a library that has a full
set of them from the steam/transition era.
