of chicago looks like that
at least from the roads that i drive going through it.
OK, now imagine a massive train depot with 2 dozen tracks, entirely underground, all looking like that. As an added bonus, there's insufficient ventilation to clear the diesel exhaust from the massive fleet of aging, poorly maintained locomotives. (The Chicago El/subway is entirely electric, but the Metra commuter rail system which serves the outlying areas is diesel powered.)
To be fair, they did a fair bit of work to clean up the north platforms a couple of years back, so those are in better shape than the south platforms I come in on. The office where I work overlooks the station, and I could see some of the work as it progressed; they removed a short section of Adams street that runs above the north platforms for several months while the work was being done. I think the plan was to do the south platforms too, but haven't seen any signs of that starting.
The station itself (once you leave the platforms and go inside) is reasonably nice; they've been fixing that up. A bit incongruous, actually.
IIRC they were also supposed to get some of the VW emissions settlement money to replace part of their locomotive fleet. Not sure what the status of that is.
You can see the railroad's maintenance tech working on the gates during that incident. Blame him.
What I didn't hear in the video was the train's horn prior to the crossing. That's required for trains at grade level crossings in most jurisdictions, but local legislation may have changed that to avoid disturbing the neighbors.
The sign is too blurry to read in the dashcam video, but Google street view has your answer: https://goo.gl/maps/vfWzSPphyhG2
I'm amazed at how calm the cop is. If I had been driving in that situation there would've been a lot of loudly exclaimed expletives flying around!
