I passed you question over to the B&O group and here's the
Having a pass-through electrical circuit
for a C-16 express car makes little sense. These cars did not have end doors
for access while in a train. Also, according to their equipment diagram,
they had a pass-though steam line, indicating no heat was provided in
As such, the cars likely did not go off
B&O lines. Interchanged express cars had to have heat and car-end access
in a train. Express cars usually had some kind of lighting in them as well,
often by means of a terminal connection.
These cars were often worked (being loaded
and unladed) in dark, covered, terminal areas. The only available light being
that of the open side door (no windows),more light would be needed inside the
cars, especially at night. So that fixture may have been a provision to power
added lights inside the car for express workers, by use of a terminal
connection - maybe at 110 volts?.
Nothing is mentioned about interior lights
in the C-16 and C-17 diagrams. But the C-15 express car diagram notes 'head
end electric' lighting. Car and head-end lighting circuits in the past were
often 32 volt systems.
