  1. Metra 553, 555

    Erie St?
  2. Metra 553, 555

    The one remaining car is 553

    This morning 8023, 8030 and 8090 are on the 130

    Apparently the security certificate has expired. cta.maths22.com uses an invalid security certificate. The certificate expired on Monday, June 11, 2018, 4:51 PM. The current time is Tuesday, June 12, 2018, 2:50 PM.

    There is always a problem with Pace on any of these! They provide both Arrival and Departure times from each stop. Obviously in most cases these are the same but at termini and major timing points such as Oakbrook where the buses wait for several minutes they are not. I have both - the free one has Pace arrivals only and no Metra. The Plus one (I think it was $1 to buy) has both arrivals and departures for Pace and schedules for Metra. I also use QuickTrack Chicago which is better for Metra (realtime) and now shows the departures for Pace by default for each stop.

    This is Ride Chicago or Ride Chicago Pro (with Pace and Metra)

    1000 is on the 80 this afternoon
  8. CTA power control

    The conductor (third) rail is supported on ceramic insulators or insulated brackets, typically at intervals of 10 feet or so. It is not continuous and typically switches from one side of the running track to the other, as well as having gaps at switches and grade crossings. Gaps are not a problem as long as the gap is not longer than the train or the train is moving fast enough to coast through the gap! Some early third rail electric locomotives where equipped with a flywheel to keep the loco moving over gaps. Higher system voltages (above 1500 v) are not considered safe as it becomes increasingly difficult to isolate the third rail. At the 600V dc used by cta, very high currents have to be used to provide the power to move the trains, which leads to considerable power loss in the system, requiring relatively closely spaced feed points (sub-stations). The optimal distance between sub-stations on the "L" is approximately two miles, dependent on loads (The more trains in a section the closer the spacing). There are currently approximately 50 substations around the "L" system. The return current usually flows through one or both running rails, and leakage to ground is not considered serious. On newer systems, such as the Docklands Light Rail in London, the third rail cross section is much smaller than conventional systems so the resistance of the third rail, and hence its current loss is much lower allowing greater distances between power stations. Another method for reducing current losses is to use a composite conductor rail of a hybrid aluminium/steel design. The aluminium is a better conductor of electricity (lower resistance), and a running face of stainless steel gives better wear.

    Actually according to the maths22 bustracker archive no cta buses at all were out on Monday between 10am and 8pm! At 8pm 6836 and 6849 were out. On Sunday 5/27 6835, 6836, 6837, 6842 and 6860 were out at various times.

    1001 was on 85A and 1002 on 205 this morning
  11. Random Metra

    No definitely South Shore. It was common in 1980s and early 1990s when SS had a shortage. Attached is 126 street running in Michigan City. Metra Locomotive and Cars, NICTD Train #117 in Michigan City, IN on July 10, 1987. When NICTD was short of cars, a Metra train was borrowed. On weekdays it came in from Michigan City in the morning and went back at night, from Marty Bernard's Flickr feed https://www.flickr.com/photos/129679309@N05/16252000229/in/photostream/
  12. Random Metra

    Probably on the South Shore. In 1989 NICTD leased a Metra diesel double decker train set and ran one trip per day each way on the South Shore as an express. The Metra train was replaced with standard South Shore cars when the trailers were added to the rolling stock in 1992. The Randolph St South Shore station downtown was above ground at that time. It was rebuilt 1998-2002 with Millenium Park built above it.
  13. New Eldorados?

    6781 was on 565 (N) according to bustracker this afternoon and 6782 was on 213 (NS)

    1930-1932 moved to P in March 2017. 1948 and 1972 were at P this morning but back on C routes for the pm rush hour. 1960 was only out in the afternoon and is probably a loan.
  15. METRA Locomotive Wish List

    The UP lines have the only F40PH-2s that have not been rebuilt to F40PH-3 (150-173). These were given mid life overhauls in 2004-6. The video of the board meeting mentioned that a full rebuild at Progress Rail of a F40PH-2 costs $2.2M. Metra can get the F59PHI for $1.3M each, they have all been overhauled in the last 5 years (some as recently as last year with an average time since rebuild of 3.2 years). It is also getting increasingly more difficult to get Original Equipment Manufacturer (OEM) spare parts for the original F40PH-2 which were built in 1983. Looks like a good deal!
