I know it’s a shot in the dark, but a brown line extension to Jefferson Park would be a dream come true.

The  Green Line re-extending to Stony Island should be seriously considered. It will not just connect to Jackson Park  but to the future Obama Presidential Library that will be in the same area.

The Pink Line actually original extended at grade to Harlem, so those parking lots are actually the former right of way! It would be nice to see it extend back to its original length

There's so many no brainer extensions that CTA could do which CMAP frustratingly holds back funding on. Very modest but solid proposals here

tbh I think the most important new thing the system needs is a north/south line along ashland or western

Extending the green line train to midway would be a dream come true

Brown line extension YEEESSSSS

Old Orchard is getting like 1,000 more apts right, the yellow line extension would be great. Literally ANY extension before 2050 would a win for the City, but heavy sigh nothing will happen until leadership at CTA changes. :(

It's frustrating that some of these extensions used to exist, or exist in part, and now we have to build them all over again. The Forest Park line, for example, used to run all the way to Mannheim & Cermak. There used to be a Humboldt Park line that ran parallel to North Avenue between Lawndale and Damen. As you note, what's now the Green line used to run to Jackson Park. And, of course, there used to be the interurbans. You could hop on a train on the Loop and go north to Milwaukee or west to Elgin, Geneva, and St. Charles. We used to have this capacity, and we threw it away because everybody needed two cars to poison the air.

All of these extensions with additional high density mixed used developments would make Chicago a even bigger and prosperous world class city!

The CTA should reconsider opening stations like California and Central and possibly Kostner on the Blue Line considering how much that would benefit those areas. They should also consider reopening Racine on the Green Line, which has already been voted on.

The New Damen CTA Green Line Station Is Finally Open Right Now

The J-park and Pink extensions existed and were removed when the CTA took over. The CTA completely removed some lines, like Humboldt Park, Stock Yards, Kenwood & 69th. Lots of stations were also removed. The North Shore line and Chicago Aurora and Elgin disappeared. They covered some of your proposed extensions. Past government administrations were stupid and shortsighted.

When I lived in Chicago I always thought it was a huge missed opportunity for a North/South line further west than the Redline that would offer almost and outer loop. It would alleviate so much car traffic, push development beyond just the lakeside and Loop.

Ahh, the sweet sounds of discussing Chicago transit 😊

Nice video!
And now for my opinions. I think CTA should use the incredibly wide right of way on the Blue line Forest Park branch to build express tracks, then restore service to some of the closed stations with locals and extend the line back out to the pre-CTA Metropolitan Railroad terminus in Westchester.
I'd also like to see an east-west line on North Ave or Fullerton Ave connecting Hermosa/Cragin/Humboldt Park with the high employment neighborhoods along Milwaukee and east of the river. Too many people have a lousy choice between slow bus rides or driving right now.

Going back to that southbound yellow line branch, i think that should become a new line

Think about it, there's a right of way between Midway and Montrose that isn't used often, i think CTA can use that, plus the Right of way from Montrose to Oakton to finally build thay "loop line" everyone has always asked for, thus eliminating the need for people to go downtown just to get another line to go somewhere else

I know it’s not an extension per se, but if purple line express trains ran all day I’d be much more likely to head downtown more than I do now. Plus some redundancy of the red and brown lines would probably be nice.

For the brown line: the buses from Jefferson Park going east are the Foster and Lawrence buses. The Lawrence bus is especially busy, and based on my experiences, a lot of people do in fact use it as an extension of the brown line to get to the North Side near the Lake and to the red line. So much crowding could be relieved, and connections to the blue line and O'Hare would be improved tremendously.

The purple:I'd like to see the line call at a few more station on the Far North Side, namely Loyola and either Bryn Mawr or Berwyn. South of Belmont, it would only call at Fullerton and then should follow the red line into the subway and turn around after serving Roosevelt station south of the Loop. It presently follows the brown line on a slow, twisty alignment and calls at all stops between the Loop and Belmont, thus kind of undoing the point of an express line to the north. I think my suggestion would make for a much faster trip from the norther suburbs and the North Side of Chicago to the Loop. There is a ton of demand already, and the purple line could be doing so much more. I'd also like to see it run all day as an express to the Loop and not just during rush hour.

Yellow: definitely should stop at Crawford, Doge, and Asbury. Also, bring the damn thing up to the mall! There are plenty of shoppers and employees who would appreciate and easier trip from Howard to get there.

Blue: the stop at Clinton St. for the OTC is a no-brainer. I'm amazed it doesn't already exist! Frankly, Chicago has too many rail termini. I"d love to see some consolidation so regional transfers would be easier.

I wish they could bring back the Humboldt Park branch
