The tracks the Virginia Railway Express ran on today used to host all kinds of important rail service. This subway-style map tells the history of some of Virginia’s railways in 1921.

Trains that used these tracks ran both express and local, and there were branches that ran as far out as Warrenton and beyond Fredericksburg.

The map’s purple line is the Potomac, Fredericksburg, & Piedmont (PF&P) line, whose acronym was sometimes jokingly said to mean “Poor Folks and Preachers.” The PF&P was a vital link to Washington from a very poor part of Virginia.

The gray line from Union Sation is the WB&A, an interurban train that linked DC to Annapolis and Baltimore.

Maps in 1921 only showed geography, making service details nearly invisible. Times and locations were only available on arcane timetables that railroad employees had to interpret.

The genius of a subway-style map is how it combines service information with geography, both of which riders need to get from A to B. Also, while surrounding geography is important, focusing on the rails themselves is the best way to illustrate the service we once had. Similar maps for other cities This is part of a bigger project whose goal is to map the 1921 railroads from the entire DC and Baltimore region. It’s a sequel to the map I made of the San Francisco Bay Area’s railroads in 1937.

I still have a lot of decisions to make in order to finish the DC/Baltimore map. Should it show through-car service, where some passenger cars were passed along from train to train? If so, how would I actually show it? What about service frequency: should there be a visible difference between once-a-day, all-day, and other kinds of service? These maps are still relevant today

Even with just the southern lines from Washington complete, it’s easy to see how history of the region’s railroads informs contemporary planning. Just recently, VRE announced it may extend service from the Manassas Line to Haymarket, reactivating a bit of a branch that once extended out beyond Front Royal. What are the other lines that we might want to start using again?

I just wrapped up a successful Kickstarter so I can print maps like these, and hopefully others from around the country, as posters. After all, it’s one thing to have this information illustrated in a JPG for transit geeks to explore, but being able to put it on a wall would mean more people would see it.

This project’s goal is to open up our region’s transit history and spark conversations about what was and might be again. What else should this map include to help it achieve that goal?
