(CHICAGO) Chicago Transit Authority officials have approved a capital plan that includes $75 million in funding for an extension of a major train line.

It’s the next step in the $2.3 billion expansion of the Red Line. City officials want to expand the line that includes stops in Chinatown and the home of the White Sox from 95th Street to 130th Street, including four new rail stations.

The $75 million investment means the city can move forward with initial engineering and analysis needed to apply for $1 billion in federal funds. City officials say the money will be funded by CTA bonds.

Mayor Rahm Emanuel announced the plans Sunday.

The city is seeking public input on plans until Wednesday. Construction on the 5.3-mile extension isn’t expected to begin until 2022.
