There are all of four stops at grade level out of over 25 or so on the Brown line in total; it is a total non-issue and does absolutely nothing to slow down the trains. It also makes living directly in front of the tracks bearable due to far less noise.

Half the line? It crosses 6 mostly small one-way residential streets on the northwest side of the city at the end of the line. The riderhip for the at-grade stations is around 8% of the Brown Line's total riderhip and 1% of the system's ridership. Actually I'm willing to bet 90% of the Brown Line riders and 95% of the people in the city don't know there are even at-grade crossing on the line up there at the end. I only knew because I dropped my boyfriend off once at a party and I noticed the L was at-grade. It doesn't cause any problems, those streets are all quiet enough, there's no heavy traffic on them.

I actually like them a lot, the trains have signal priority since the 115,000 passengers on the Brown Line every day is far above any cars that pass on those streets so it doesn't slow them down, and I think they're really funky and add a very unique aspect to the area. I want to go see them in person sometime.

They've been doing it for 107 years on that section, no one has proposed to change anything.

Not only the Brown Line but also the ends of the Pink Line in Cicero and the Purple Line north of Isabella Street on the Wilmette/Evanston border, along with much of the Yellow Line, have surface-running sections with grade crossings.

But these are all short stretches, no match for Tokyo where huge sections of commuter rail lines providing metro-service frequency cross multiple roads at grade, at rush hour providing just 45 seconds of open road/pedestrian traffic per hour. And those grade crossings in Tokyo are in much busier metropolitan areas than where the CTA crosses at grade. No one would argue Tokyo is not a world-class city due to this.

What I find more peculiar is that the mainline tracks feeding into Union Station from the north cross both Canal Street and Clinton Street at grade, and this is in a relatively busy West Loop area.

I think the normal reaction would be to just close off clinton and canal at the tracks, but there are very large periods of time that the roads can be open during the nights and mid-day, and they're very little used, they both dead end at Kinzie street (not a busy street) right after they cross the railroad tracks. It's easiest to just leave them open for local traffic. Almost all through traffic travels on the much busier Des Plaines and Halsted streets just to the west as people know those streets have bridges and are both much more through streets than Canal and Clinton are once they get north of Fulton.

Brown Line service expansion - 11.02.2014

So currently late-night trains on the Brown Line only run between Belmont and Kimball, necessitating a cross-platform transfer to/from the Red Line in order to continue further downtown or uptown.

This will change on Sunday -- for one day per week. On Sunday and holidays, all Brown Line trains will run from the Loop to Kimball.

The Englewood Flyover is finally complete! There are some cool shots of Rock Island Metra trains traversing the flyover, Amtrak trains, a BNSF freight, as well as a few CTA Red Line trains.

Are you ready for winter? Check this video out of the CTA Loop Junction 12 in the dead of winter.

Regarding the issue of level crossing for some of the lines...how do they manage the issue of the electrified 3rd rail at/near the crossing?

the third rail doesn't cross the intersection, and the car simply goes unpowered while crossing. Momentum and power from other cars on the train which are still on the third rail allows it to continue through without notice, though. Its like one train car at a time loses power for a second, then the next one loses power, the train only really loses a small amount of its propulsion.

T

he train tracks are amazingly exposed to pedestrians. Other than an area of boards turned on end making it hard to walk across and to alert you to stay off, if you wanted you could walk right up and electrocute yourself.

They're quiet streets though and the area doesn't see many unknowing visitors, so occurrences of people killing themselves are extremely rare. The last instance I found if someone dying along those few streets exposed at the end of the line was back in 1977.

There are on average 11 people a year who die on the tracks, mostly from suicide, but it's decades between people dying at these crossings.

The L wall is amazingly cool! Looks like something I'd do if I had a spare 10 grand sitting around.

They're trying to be at least vaguely non-denominational.
