Mass transit became an immediate casualty of the COVID-19 pandemic last year, as nationwide stay-at-home orders and crowding concerns drove Americans away from trains and buses.

The drop-off did not spare Chicago-area transit networks, which saw a freefall in ridership in April and May 2020, according to a March 25 report from the Illinois Economic Policy Institute. Even as the region began to partially reopen in June, CTA buses saw a 50 percent decline in trips compared to 2019, while CTA trains suffered a loss of 77 percent and Metra lost 89 percent of its riders.
