What exists of that first train (Chicago & Galena > Union/CNW) would be under the roadbed of the current UP West Metra line. Supposedly if one is lucky, a ghostly image of Abe Lincoln's funeral train becomes visible from the 31st street bridge over the tracks from time to time... Just a chicago ghost story... For all I know it's entirely false... |

Convenient for them. Period. Congestion taxing won't make a friggin difference in the traffic congestion patterns because the time people have to be at work will remain the same. Employers won't care, it's what they want, when they want. Those with the freedom to change their start times to avoid traffic have already done so. |

Judy's car won't. And I'll bet that they never take away the brake pedal away from the driver. And that's how a blow out turns into a spin. > And, if a blowout occurs anyway (such as by hitting a pothole or other > road debris), not only will the computer be more capable of safely > guiding the vehicle to the side of the road, but all the other > vehicles in close proximity will automatically make way for the > disabled car, thanks to the local area wireless network that the cars > will communicate over. You're asking a lot of this computer. A lot from the lowest beater on the road. And if you think a blow out is the worst thing that can happen to a beater, you haven't spent enough time on the south side of chicago to see what utter crap people will drive. Are you sure that computer will be able to tell a blow out from a busted ball joint? how will it handle a locked rear axle because the diff fluid leaked out? There are so many possible spectactular failures. The first one at 90mph will insure that the computer speed is dropped to 50mph or less. Even if it's initially for a few months to improve the system.... remember that temporary speed limit we got when Nixon was office that lasted for over 20 years and in some parts of the nation it's still in effect? |

Other than the right-of-way itself, there probably isn't much. Consider the standards of railway construction in the mid 19th century (at least in the midwest USA). Not much could've lasted, what with heavier cars, widening of ROW for more tracks, and so forth. > Not sure where the "Class I mainline railroad" bit comes from, If you can run 100 car double stack container or 15 car double-deck commuter trains on it, that's probably a mainline railroad. > but the > structures in question were originally built for a predecessor to the > Chicago, Milwaukee, and St. Paul - most definitely a mainline > railroad. Yes, but that line was taken over by the CRT/CNS&M back in the 1920's. The track elevation was done by the CRT, not the Milwaukee Road. http://www.chicago-l.org/stations/howard.html >The Chicago, North Shore & Milwaukee (North Shore Line) also > ran over this line, and its trains routinesly reached speeds of 80+ > MPH in places (though definitely not over those bridges). And not over that line at all. The 90 MPH operation, what there was, was over the grade level Skokie Valley route further inland. What's left of that is the CTA Yellow Line. > Finally, the > Metra (ex C&NW) runs right next to the "L" through this area, and > those viaducts also date from 1910. True, and those were maintained by the C&NW (now UP).One of the reasons that the C&NW didn't go to s--t like the Milwaukee & Rock Island is that the C&NW was anal about maintaining its physical plant. > Anyway, I was merely responding to Brent's comment that Metra trains > seem to travel at 25 MPH, and was speculating at a possible > explanation. If Brent thinks Metra trains typically run at 25 MPH, either he ain't seen or rode on one lately, or he had his mental timeline artificially altered ('shrooms and peyote can do that). > Does the Metra/UP North Line (ex-C&NW Milwaukee Division) qualify as a > mainline railroad anymore? Or is it now relegated to commuter status? AFAIK, it's still part of the UP, and the trains run at max Metra speed, but there's not much if any freight traffic. -- Ned Carlson www.tubezone.net South Side of Chicago,IL USA 2/3/2006 1:14:39 AM |

Perhaps there are a few > 150-year-old ones left, as well. That's all concrete. You have to go back further. Try stone and 19th century riveted iron: http://www.iit.edu/images_portal/photogrid_about_us.jpg http://www.iit.edu/publications/cont...tos/metra5.jpg http://www.worldofstock.com/slides/AOB1510.jpg However it was apparently replaced in 2004: http://images.google.com/images?q=me...et&btnG=Search The original structure dated from at least the 1890s and was constructed in a manner that was consistant with the green line 'L' ( http://www.thisisgrand.org/photo8.htm ) and IIT's main building ( http://www.aviso.net/chicago/higherlearning/iit/ ) which is right next to it. These are the metra tracks directly east of the dan-ryan expressway BTW. |

That may be true today, but during the late 19th/early 20th century, generally it wasn't. Also, during the early 20th century most of the heavily used mainline track inside the city was elevated to eliminate grade crossings, same as happened in NYC. The original ROW is way down below present day tracks. Furthermore, much of the actual ground & street level of the City of Chicago was raised by fill in order to eliminate marshes. In some cases you can see this first hand, where porches and/or backyards of housing that predated the re-levelling are below current street level. > >>Yes, but that line was taken over by the CRT/CNS&M back in the >>1920's.

The line south of that point was > elevated during 1908 - 1910, and that work was done by the St. Paul. > Grover Garfield (who has researched this more thoroughly that you or I) states: " "L" service entered Evanston by way of an agreement to use the tracks of the Chicago, Milwaukee and St. Paul Railway on May 16, 1908, replacing the steam service that the St. Paul had previously provided. The steam railroad's original station remained, though the "L" constructed a high-level platform station of simple frame construction, all of which was demolished during the elevation of the tracks in 1909. (as per the 1907 franchise agreement from the City of Evanston)." "In 1908, the Northwestern "L" was extended over the tracks of the Chicago, Milwaukee & St. Paul Railway's tracks to Evanston. The tracks descended to grade-level north of Wilson, but the original station remained in use." IOW, no elevation was done until the L trains came, and it was done expressly to facilitate L trains, the CM&StP steam passenger service expired the same day the L trains showed up. > Is that why some of those bridges haven't been painted since 1974, and > are now rusting away? In the 1970's, Northwestern Industries unloaded its railroad on its employees, and Metra took over the commuter rail service. Don't blame this on Ben Heineman and the old C&NW! BTW, the idea of double-deck "commuter streamliners" in Chicago was invented by the Burlington in 1950. Not by the C&NW. -- Ned Carlson www.tubezone.net South Side of Chicago,IL USA 2/4/2006 2:21:45 AM |
