Of all of the Pennsylvania Railroad main lines, such as the main line across Pennsylvania, the Panhandle and Fort Wayne lines, did all of these lines have cab signals and line side block and interlocking signals? See this link of the NS OCS train "Covered Wagons Roll Through NE Ohio" via the following link:

Are the style position light signals block signals that run with cab signal display also. The Boston line has cab signal operations with interlocking signals, however, there are no block signals. Did the old NYC and the B&O use the same kind of signals on their main lines.
