[PRCo] Re: Interurban PCCs ???

[Boris Cefer]

But the earlier books appear more detailed.
There are possibly some data in GE wiring diagrams, but I haven't seen any
except for the early air cars (1000-1200 series), but they don't make me
happy because the early GE design was terribly complicated. GE parts
catalogs do not contain any useful data, these are endless lists of parts
with some pictures only.

And an another question is still the Westinghouse 1700s. Their equipment
allowed to change the balancing speed by means of higher field shunting.
Only four small jumpers joined to the field shunting resistors increased the
balancing speed several mph, but we don't have any evidence whether PRCo or
later PAAC did not dismantle them to avoid eventual accidents due extremely
high speed over irregular track. Memory is sometimes very delusive and some
few can tell us what the top speed was 50 years back. Our friends at PTM
would have to check whether the jumpers on 1711 are in place...
