notice that 1015 still has an Air Cooled Turbo.
on Erie the freight Alcos got Water cooled turbos 1st.
some of the passenger RS-2/3s made it to 1965 with
the aircooled turbos,and there are a few pics of Gray RS's
with them.
believe the PAs also got Water Cooled Turbos early,but it
was hard to see the roofs on them .
later they closed the Waldwick Subway when the walkway
overpass was built.
but by then the PAs were west in Freight service and rarely
showed up in the east.
