Here’s an 1850 map of the Philadelphia, Wilmington & Baltimore Railroad, the line that erected the Newkirk Monument. One of the virtues of this map is that it shows just how direct was the new railroad line between its principal cities — so direct that Amtrak still uses most of the route for its Northeast Corridor trains.
(Want to print out the map and frame it? We don’t blame you. Luckily, you can download a giant scan from its page at the Library of Congress.)
