[PRCo] Re: Pgh__--__San--Fran__Connection

[Edward H. Lybarger]

GE also supplied motors for PRCo LF cars...#247s.  Why the small motors were
not successful remains unexplained from a technological basis, though Fred's
observation may have merit.  Question:  What kind of grades were TYPICAL of
SF routes?  Could it be that the cars couldn't maintain schedules because
the grades slowed them down?

Through the Untied Railroads  (Ed, John, Bill, Don may be able to give
us more historical information)  there was a connection between these
two cities.       This was borne out in home built  #0301  aka  #0401
of the Market Street Railway, predecessor of the Muni, in that it is a
Low-Floor design of 1915 that used the same trucks as PRCo Low-Floor
cars.       Text from White Front Cars of San Francisco indicates that
GE  motors were used  --  PRCo contracted with Westinghouse for the
small motors.
#0301 was not successful in San Francisco and I think the difference is
that SF has Grades and is Very Short Haul with Very Closely spaced stops
while PRCo has Hills and some grades but less frequent and less closely
spaced stops.       Text indicates that the cars were very successful in
Pgh.

Five  URLs  below showing photos and text.       You may need to adjust
the size of the scan to make the text legible  --  experimented with
this before sending and it is quite satisfactory.
