It was always a problem but that was an exceptionally severe winter
with repeated snow and ice storms. I've heard that decade referred
to as the "Mini-Maunder Minimum" with cool summers and devilishly
cold winters (at least along the east coast). I moved to D. C. in
1977 just in time for a storm that paralyzed the city for nearly a
week! And stupid me - I thought I was done shoveling snow - Not!
The weather pattern had persisted for a few years and I presume the
PRR tossed in the towel and fixed the problem It apparently worked
and while there were delays due to frozen pipes and knee deep snow at
stations, the GG1s weren't conking out.
Raleigh in Maine where it's fixin' to snow!
