Pretty sure the Purple Line won’t be running that fast through the station. Sheridan probably won’t even be reconstructed with double island platforms, since Evanston-based Cubs fans can now transfer at Wilson to reach Addison.

I could be wrong but I don't think the Sheridan stop for Purple Line trains for Cub games was eliminated even with the addition of the Wilson stop.  Therefore I don't think Loyola or Wilson will make it difference so long as Sheridan is open in its current state.   Now i$ Sheridan is rebuilt by Irving Park and is built with only one island platform,  it might be a different story.

There's no longer any note of it on CTA maps, which happened after the new Wilson station opened. But, I did check the timetable, and there's still a note that Loop-bound trains stop for night games. Kind of surprised they kept that after Wilson, but like you said, we'll see if that arrangement holds up after Sheridan's reconstruction

Keeping Sheridan probably helps stops the crush loads from all piling off at Addison. Sheridan is kinda walking distance so you can hop straight off a purple after instead of cramming into a red line to Addison from Wilson

Yeah, but humans are lazy. A 7-10 minute walk vs <2, I know which one is winning out more times out of 10. I agree with you, I'm only saying because Wilson now serves people, there's less of a need to keep Sheridan as a double island platform.

Yeah especially with it being the next stop. Purple is basically gonna have to be an X route equivalent for the red line and be put in the subway at some point.

Ok, so if I’m reading this right, the rest of the project is track reconstruction, nothing major

They have to rebuild the structure, all while trains are on the track next door. . Im trying to figure out the temp track 1. Why build it if tracks 3 and 4 get fixed first. If because of a structural shift then they would need temp track 2. I can only think that maybe its a jump track this way they can take out track four and still have 4 tracks???

It’s on one of the RPM related pages but I forgot exactly what they said.  I THINK it was built during the flyover phase because they were already doing work in that area but it’s supposed to be for easing the impact of track closures. Maybe demand is too high (or at least was projected to be too high if it wasn’t for the virus) to afford another 3 track. I don’t think they reduced frequency for red and purple for the Lawrence section

That does make sense. They cant have brown red and purple all sharing a track. So sounds like temp track 1 is for brown line sb only perhaps with a straight connection to belmont. (No connection to clark junction.) That would simplify a clark junction rehab. What might be kind of smart would be to keep it a straight link and only have tracks 2 and 3 use that junction, making it a crossover instead. Have the outer tracks use the one south of belmont. Now that we have a flyover we dont need a junction.

I think in that FB post they said they’re keeping it tor operational redundancy

The temporary track is to sustain Loop-bound Brown Line service while tracks 1 and 2 are being rebuilt. During demolition between Belmont and Cornelia Avenues, part of the junction will be demolished which means that Loop-bound Brown Line trains will not be able to proceed without a temporary track.

Like BusHunter said, they can't have Red, Purple, and Brown Lines all single-tracking. We had all three lines going northbound single-tracking at Belmont while they install the 'slide-in' piece for the Red-Purple Bypass from October 25 thru November 18; and the mass congestion that resulted was TORTUROUS!!!

Yeah having all three lines only on one track will cause a huge blood rush to our heads, I’ll at least keep another track or two available while they do the other two or three in order to keep trains in descent control instead of holding up so much traffic. Bad enough this is another piece to the RPM construction since it is the biggest project of CTA HISTORY!!!!

this weekend they’re connecting track 3 (NB howard track) to track 2 (SB 95th trains) the next 2 weekends crews will work on installing interlocking for SB brown line trains to use the temporary track thru belmont

I began to see posters in Evanston petitioning for the rebuild of the Evanston Branch along the Purple Line. Out of all the stations between Howard and Linden, Davis is the only wheelchair-accessible station, and a lot of the infrastructure is aging due to the fact that it's all century-old. Could it be RPM Phase Two?

It wasn't made official by the CTA. Even if it says so in the powerpoint, CTA may alter it.

Could the Authority shut down the Purple Line between South Blvd. & Central in order to rebuild the stations thereupon to island platforms which would require only one elevator from the ground to the platform? ?

Typed North when it should have been South.

If they decide to do that   im sure ot would have to happen in Phase 3.  I would imagine the entire Purple branch would be shut down with only express rush service from Howard.

Wouldn't it be more likely that one track at a time would be taken out of service and there would be no PLE at all, just PLS? While single-island platforms seem enticing, it feels like it would be more work (and ROW acquisition) than just modernizing the existing platforms
