One more story and I will quit: The amazing thing about the railroad industry is how fast it grew and how well built the structures were. Some of them still in use today are well over 100 years old. Lots of the bridges and tressels were built in the 1800s. The subway system in New York City was built around 1890, but the most durable has been the Chicago El. It was finished and opened in October, 1893. El means Elevated, and the steel infrastructure that supports the track, two stories off the ground, hasn't changed since it was built. The El forms a 2 mile loop around downtown Chicago before branching off to different destinations. Since the early 1900s, about 1600 trains a day make the loop.
