CTA Green Line Runs Shuttle Buses on 63rd Branch

Chicago's Green Line is operating with shuttle buses replacing train service on the 63rd Street branch, transit officials said. The service change affects riders traveling to stations on the southern portion of the line, though the CTA hasn't specified when normal train service will resume. Officials said the modifications are part of ongoing construction work that began in 2024 and will continue through 2025.

Construction Work Prompts Service Changes

The shuttle bus replacement is part of infrastructure improvements on the Green Line's 63rd Street branch, according to the transit agency. Officials said the work aims to upgrade aging rail infrastructure, though specific details about the scope of construction weren't available by publication time. The Green Line, which includes some of Chicago's oldest elevated rail dating to the 1890s, spans 20.5 miles with 30 stations across the system. Transit agencies typically close sections of track for major construction projects when work can't be completed during overnight hours.

Shuttle Buses Replace Train Service

The CTA is running shuttle buses to serve stations on the affected 63rd Street branch while construction continues. Officials haven't said how many riders are impacted by the service change or provided ridership data for the affected section. The agency also didn't release cost estimates for the construction project or specify funding sources. The Green Line typically serves riders traveling between downtown Chicago and neighborhoods on the city's South and West sides, with the 63rd branch extending to Ashland/63rd and Cottage Grove stations.

Timeline Remains Unclear

The service disruption has been in effect since 2024 and will continue through 2025, officials said, though a specific completion date wasn't provided. The CTA typically announces project timelines several months in advance for major construction work, but detailed schedule information for this project wasn't immediately available. Officials said riders should expect the shuttle bus service to remain in place until construction is complete.

Riders Should Plan for Extra Travel Time

Commuters using the 63rd Street branch should allow additional time for their trips while shuttle buses replace train service. The service change may result in longer travel times compared to normal rail operations, though officials didn't provide specific estimates.
