[PRCo] Re: Interurban PCCs ???

[James B. Holland]

Time to speculate why GE was so Resistant to include specific 
information!! :-)

Various PCCs had been  *tested*  for interurban service according to 
that 1952 ERA type dissertation on the PRCo Interurbans as well as the 
Ira Swett article on Charleroi  --  but they weren't specific about the 
tests and whether or not the PCCs were run beyond Library  --  we know 
that they were used as trippers this far and even the PTM calendar shows 
an 1100 used for Fair Grounds tripper about 1949 or 1950.

With 1613 and 1614 converted for interurban Test service within 6-months 
of delivery  (at least for 1613)  PRCo was  *probably*  considering PCCs 
for interurban service even as the 1601s were ordered.       Guess we 
shall never know For Sure without something turning up in the archives.
