THE SIGNAL BOX

OVERSEAS

PRR INTERLOCKING TOWERS
Zoo to Nassau

by Mike Brotzman

The Pennsylvania Railroad rightly proclaimed itself the Standard Railroad of the World. At one point, one of the largest corporations in America with over 300,000 workers, the PRR connected some of the most industrial and densely populated regions in the country. The PRR prided itself on having the highest quality system by constructing exceptionally robust infrastructure engineering and pioneering new railroad technologies.

In fact, the PRR had little choice in the matter. Without these measures the railroad would have been simply flooded over by the seer volume of things it needed to transport. From thousands of daily commuters to premier intercity trains to trains of coal and ore hundreds of cars long, the PRR hauled it fast and on time. The PRR's commitment to quality was evident everywhere, from its rail to its rolling stock, but the PRR left a particularly rich legacy in that of its interlocking towers, a few of which I will try to illustrate.
