My guess would be Chicago–but that is just a guess. With all major railroads entering or leaving Chicago from the east, north, south, and west, it sounds like the obvious choice. But I may be wrong
Take it from me, it’s Chicago. I also have to wonder (now that we’re on the subject), what percentage of the total U.S. number of crossings are in each state, and what the percentage would be in the five or six county “Metro Chicago” area.
I would agree with the others – Chicago. All roads lead to Chicago.
Second busiest would be the Los Angeles metropolitan area.
Third choice would by the greater New York area, particularly those lines and routes served by the Metropolitan Transit Authority, with Long Island and the Long Island RR having the most grade crossings in the region.
Which type do you mean, vehicular or rail? Do you include non-grade level crossings? If it’s vehicular grade level crossings, there are suprisingly few in the city proper because of city ordinances. For example, the C&NW commuter routes are all above or below grade.
Good point–I guess we’re talking about vehicular/pedestrian crossings, as opposed to railroad crossings, as in Interlockings plus Brighton Park. There should be a DOT list of all railroad/non-railroad crossings (including grade separations) made a few decades back that would give a rough idea of what to expect. I don’t know how recently (or how well) it’s been kept updated, though–I’ve found a few mistakes in descriptions of specific crossings on my “home” line that were the fault of faulty updating.
Chicago was a true pioneer in the early part of the last century, requiring that crossings in the city be grade separated. I don’t know what the criteria for this were, as some crossings still existed (and some have been built more recently, such as the Kilbourn Avenue grade crossing on UP West).
Now: did you know that the city also undertook a study on electrification of all of the major railroad lines–freight and passenger–in the city and environs? What an amazing thing that would have been!
I doubt you’ll find one. After I was tipped off to it, I had to go to the Harold Washington Library downtown, go to the rare books section, have my pens confiscated, and practically sign my life away just to look at it.
That question is beyond the ability of the FRA database to answer as it applies to a specific route. But here is a state-by-state breakdown of grade crossings for Amtrak -
CT - 60
MA - 3
RI - 11
NJ - 11
DE - 4
MD - 5
NY - 4
If you would like, I could provide you with the locations, and you could see if they happen to be on the Acela line. [4:-)]
If I am correct, the N.E. Corridor Improvement Project of the 1970’s and 1980’s virtually eliminated all (but less than a handfull) of crossings between Washington D. C. and New York…can’t speak for north of N.Y.
