Alright, if you’re standing here eye-level with the rumble and clatter of the passing trains, you’ve already met one of Chicago’s iconic sounds-the “L.” That’s short for “elevated,” and for today’s show, you’re standing at the very heart of it: The Loop.
Now, The Loop isn’t just a neat circle of steel tracks. It’s Chicago’s main artery-a 1.8-mile-long rectangle of elevated rails floating above the downtown mayhem, tracing out a box between Lake Street up north, Wabash Avenue to the east, Van Buren down south, and Wells Street to the west. If you look up, you might spot the Brown Line, the Pink, or maybe the always-busy Green Line, screeching along as if late for a big interview.
But rewind about 130 years and this scene would’ve looked… well, a lot woollier. Late 1800s Chicago was a wild, booming city-walkable at first, then exploding outward faster than anyone could lay track. At that time, the three big elevated train companies each had their own turf and, believe it or not, none wanted to bring all their passengers into this very part of downtown. Why? Simple: building here was expensive-and the local power brokers had about as much interest in rapid transit as a snowstorm in July.
Enter Charles Tyson Yerkes. If Chicago history were a soap opera, Yerkes would be the guy everyone loves to hate-a cross between a railroad tycoon and a pocket-sized political hurricane. He saw an opportunity: bully, bribe, and combine those independent lines into a “Union Loop.” As for city council support? Well, he didn’t exactly play by the rules. Yerkes handed out bribes the way Oprah gives away cars. When he got himself a fifty-year franchise deal-worth millions, or about tens of millions in today’s dollars-public outrage sent him running out of town. Politics in Chicago… some things never really change.
Despite the drama, by 1897, the Loop was up and running-and instantly mobbed. Travelers swapped sardine-can conditions for a ride straight into the pulsing core of the city. Jockeying for elbow room became the new normal. In fact, those original edges-of-town terminals had to reopen just to handle all the spillover. The railways had accidentally created, and named, downtown Chicago itself: “The Loop.” Pretty catchy for a city center built on a scandal.
Through the twentieth century, the Loop wasn’t always so beloved. By the 1970s, with ridership falling off and folks abandoning trains for cars, there was real talk of tearing it all down. Imagine-a giant parking lot in the middle of the city instead of these sprawling tracks. But nostalgia is a powerful opponent, and by the 1980s, people realized you can’t just bulldoze your personality. Ridership rebounded, and the Loop remains the beating-maybe slightly chaotic-heart of Chicago, with more than 40,000 riders hopping on each day.
Today, eight busy stations dot these tracks. And right up above-if you know what you’re looking for-you’ll spot Tower 12 and Tower 18, control towers that once oversaw so many switches and signals that, at one point, Tower 18 was the busiest railroad interlocking on the planet. If you think air traffic controllers have it tough, try deciphering a tangle of Loop trains at rush hour.
So-there you have it. The Loop: part travel solution, part architectural dare, part political plot twist. Look up, take in the steel and movement, and remember… Chicago has always been a city willing to build right over its own head.
When you’re ready, head north for about five minutes, and you’ll find yourself at Old St. Patrick’s Church (Chicago).
