Baltimore & Ohio Railroad

Interior of East Norwood tower
Photograph 16/9/1927, from the collection of Dr. J W F Scrimgeour

A view of the interior of East Norwood tower, in the suburbs of Cincinnati, showing the GRS all-electric "interlocking machine" installed in 1904. The large circular indicators above the machine indicate track circuits and signals.

This tower controlled the flat crossing of two double lines - the Baltimore & Ohio and the Cincinnati, Lebanon and Northern. The latter was one of a number of American Railroad holding companies which did not itself operate a single train. Ownership of this company appears complex, but in simple terms it appears to have been the Pennsylvania RR in one of its corporate disguises.
