#Power Directors Office | Tracking the Light

Two weeks ago, I visited the preserved Power Directors Office (PDO) located within the Harrisburg, Pa., station.

This historic former Pennsylvania Railroad facility is a vestige of its grand late-1930s electrification to Harrisburg, that consisted of Mainlines and connecting routes

This office was used to control and balance the distribution of high-voltage alternating current electricity to the various lines. Today it presents a fascinating map of the western extent of PRR’s electrification.

To my eyes, it has the look and aroma of an enormous Lionel electric train set from the World War II era. The style of the control panels and wiring reminds of my dad’s train sets from the post war period.

Dan Cupper arranged the tour, and NRHS’s Jim Nowotarski provided an excellent and exceptionally detailed explaination of how the desk performed and the background behind its restoration. I’ll need to sit through this talk several more times before I can begin to absorb the detail of this amazing installation.

The desk was closed by Amtrak in 2013, and its remaining functions transfered to its Centralized Electrification and Traffic Control office in Wilmington, Delaware.

The once important role of the PDO reveals the long-term failures of short-sighted decisions made during the Conrail-era, when freight traffic was routed away from former PRR routes east of Harrisburg, and freight-only lines stripped of their electrification, and in some cases abandoned altogether.

What may have made operational sense 45 years ago, represents a poor use of resources and infrastructure in the long term. Consider that in most of the industrialized world, railroad electrification has been gradually expanded, and not abandoned.
