I can't help but wonder why the companies that built what became the L didn't do the same on their trunk lines and branches!
A good look at the histories of the lines might help. The Chicago "L" lines once had interurbans and freight trains on their tracks and was built by competing yet cooperating companies. By the time the lines came under the CTA umbrella they were basically bankrupt - with not a lot of money for improvements.

The crossovers work ... and have worked for a long time. The flyover will work better.

I understand that by the time of CTA things had evolved (devolved?) to where a major reconstruction couldn't happen. I also understand why having flyovers entering the Loop couldn't work. I guess I wonder why when the independent companies were first building the elevateds and adjacent properties weren't as developed they didn't install such features to prevent eventual traffic conflicts as the ridership and number of trains grew.

On the flip side, taking the Northside lines as an example, if they could make it work using just crossovers for local, express, Ravenswood, and North Shore trains operating far greater frequencies, why the need now for a flyover?

It may not be needed ... but now is a good opportunity to look at the option (while the rest of Red-Purple is modernized). If they decide not to change Clark Jct the plan will just sit for another 25-50 years (with the rest of the improvements completed).

The May issue of Metra's BILEVEL briefly mentions a project to renew A-5 interlocking. Is there still an operator controlling this interlocking? What will be accomplished by the project and will more than one track at a time be taken out of service during the work periods?

If you haven't done so already, please scroll down a bit in this forum and see topic "A5 project" for more details...

Understand that the Englewood Flyover is now in service for midday trains, operating at ?30 MPH while construction continues. Should be fully in service next month.

Hustle up investor cash, make the minimum spend to meet the franchise requirements, and pocket the rest.

In addition, there were two or three generations worth of transit planners convinced that a nice, new subway would replace the inadequate elevated structures. It's only been the last thirty years where the Loop wouldn't be torn down and the lines feeding it replaced by subways.

Only slightly commuter related but over the weekend, a major step in the grade separation of the ex-Milwaukee Road Cut-off at Irving Park Road occurred. From B-17 interlocking, Track 1 now goes to the bridge rather than the ground level track. I don't think it's in-service yet as on Track 2, a new switch provides access to ground-level Track 1 at the west end of B-17. Metra was impacted over the weekend with all ops on Track 2 B-17 to B-12 Saturday while on Sunday, all passenger ops were on Track 1 Roselle to B-12 while I saw a freight from Bensenville yard "wrong-railing" on 2 out to Roselle.

And it appears from the state of things (observed from my Metra train home last night) that they are ready to cut Cut-off Track 2 over to the new Irving Park Rd. bridge this weekend.

Now we just need IDOT to do the needed rebuilding of the Irving Park Rd. / York Rd. intersection and we can actually drive under the new bridge (currently closed under the bridge after several trucks ignored low clearance signs and hit it all in the first few hours after the bridge was put in it's final position).

Someone should set up a webcam at the bridge, like the infamous Gregson St. bridge in Durham, NC. A crash beam had to be installed to protect the bridge.

Work is continuing on the Englewood Flyover - it appears provisions are being provided to allow quadruple-tracking in the near future. The piers holding the new viaduct up are being widened to twice their previous width (on the south side of the structure). Unsure if they'll be putting up a new, parallel viaduct at this time but I suppose it's worth noting that the Metra signage previously mounted on the old bridge has yet to be attached to the new one.

The viaduct was announced as a three track structure.

I took a look this weekend ... the viaducts to the north of the expressway are two tracks on the west bridge, one track on the east bridge (over NS and 63rd St an 61st St). The viaduct immediately south of the expressway is two two track bridges (over Wentworth). I believe the eastern viaduct has not changed

Cn Freeport construction
I went by the CN at Rt 47 East of Burlington and west of Plato Center.
There was a large project and crew on site to the west of Rt 47.

Any idea of the project scope?
