PC: another PC article, from 1977

[kelkel@xxxxxxxxxxxxx (Countryman, Kelly)]

While looking through my stack of old magazine came across
"Railway Quarterly" vol 1 # 1 dated fall 77.
Has the Predecessors of Conrail in it with 10 pages on the
Penn Central plus a couple of extra pics.
This is the only issue I have, does anyone know if latter issues
covered PC at all.
