Notes on Viewing Images

All of these images are scanned at a sufficiently high resolution that the smallest text is quite easily readable, though it may not be publication quality. If you don't see the image that way, or you don't see the track lines at all, zoom the image in closer to a 1:1 setting. Most browsers do that automatically; not all image programs do.

Some browsers cannot load some of these images; they appear to have some internal maximum that is being exceeded. You will have to download the image and use an image editing program to view it. Use the right mouse button over the image and choose "save as..." from the pop-up menu (or however your browser supports such things). If sufficient numbers of visitors have not the means to view some of these images, and you let me know, I'll cut the problem images into two halves.


Maps from the Centennial History of the PRR

Quite obviously, these are maps scanned in from the book. These include a large overview of Pennsylvania and several maps of historical interest demonstrating lines added to the PRR in the late XIX and early XX century. Unfortunately, map coverage in the Centennial History is quite poor: much of the PRR is not covered. Lines West is particularly poorly covered.

Interlocking Diagrams (includes yards)

Interlocking diagrams came in a loose-bound booklet, each booklet covering a single PRR division. Each page contained a diagram of one interlocking. Sometimes 2 or 3 interlockings, all controlled from the same location, were on one page. Diagrams of major yards are included as well.

Interlocking diagrams concentrated on the interlocking arrangement, signals, switches, etc., and the dates of updates. Obviously, this meant that only mainlines and major branches are covered, as a rule. The trackage outside of interlockings was abridged, showing only signals (usually). The level of detail varies, possibly depending on the year drawn, possibly on the person doing the drawing.

Since divisional boundaries varied so much, I have chosen to organize these maps using my own schema, in somewhat logical (the reader may disagree :-) regions from east to west. Interspersed with the interlocking diagrams are diagrams of trackage that appeared in employee timetables. These ETT diagrams are placed in the same geographical order as the mainline diagrams.

Track Charts

Track maps were the fanfold booklets of an entire mainline, branch, or secondary track. In contrast to interlocking diagrams, track diagrams showed the the track, curvature, and grade, and only cursorily showed trackside structures or signals.

None are available as yet, but just as soon as I'm done scanning in interlocking diagrams, track charts will be next. Be patient. I have a bunch of my own and will, of course, be willing to borrow charts in the collections of other PRR fans for scanning.

Other Maps

PRR Electrification Map

This is the map, reprinted in several sources including Dan Cupper's and Fred Abendschein's GG1 book, detailing the portions of the PRR that were electrified in the 1930s. Despite several scans at different resolutions, I was unable to resolve some double track into 2 black lines. If anyone has a better copy of the map, please let me know.

Zoo Interlocking

My thanks to Dr. Matthew Mitchell for providing these maps of the current (1994) and proposed (2000) layouts for the trackage at Zoo interlocking in Philadelphia. The originals are to be found on the DVARP site, in what is now the current issue of their newsletter, but which will at some point become a past issue. For now, you may proceed directly.
