If your ancestors lived or worked in New York City, did you know you can follow them home from work? At least virtually.
David Pirmann runs a website dedicated to the history of the New York City subway system. NYCSubway.org includes great historical background, photos, maps and other documents.
Start by reading about elevated rail service that began in the 1860s and the development of the transit system since then. Then consult route maps for several time periods, either in the Historical Maps section or the Line by Line Guide (both under the Maps and Stations tab).
The fun part is browsing the rest of the site: learn how “The Great White Hurricane” snowstorm of 1888 paralyzed the city, or how things have worked behind the scenes (fares, power, signals, etc). You can even check out images of abandoned stations and old cars.
Thanks to Gizmodo.com for an article that pointed me to this fun resource.
