Why Does Chicago's L Train Have So Many Abandoned Stations?

Chicago's L train has been running for over 130 years — but not every station made it to the present. Dozens of platforms were shut down, sealed off, and left to decay right above the city's streets. Some closed overnight. Some were erased by highway construction. Some were simply forgotten. In this video, we uncover the real story behind Chicago's ghost stations — who built them, why they were abandoned, and what their disappearance meant for the neighborhoods left behind.
