Really interesting. Never having been in the Chicago Union Station Interlocking Tower, is this the tower that controlled the south side, i.e. CB&Q etc., or the north side, i.e. C&NW and Milwaukee Road?



EDIT:

I have since found out that this is the Harrison Street Tower which controls the south portion of Chicago Union Station, for the station platforms to the CB&Q and PRR coach yards.

Lots of switches to control = lots of stress and headaches! Hope they had enough Asperin.

Actually not as stressful as you would think (certainly NOT like an air port control tower). Having made a number of trips into the DL&W Hoboken Terminal Tower during the morning in-bound commuter rush in the late 1950s, there is definitely LOTS of "activity". However, there was always one or two Signal Maintainers "on duty" in order to assist in any potential "delays".

I looked up the M4 class on the cab to find they were 0-8-0 switchers on the C&NWs. For modelers, note the canvas (rear of cab and over window) to keep out the cold on the cab and the low hanging piping that one might think would get fouled/ snagged while operating.

No signs of global warming on that December day in Chicago!

Thanks again for posting.

Just saw this. Few observations about this pic...

I was born (March 1952) and raised in KC KS/MO. We moved back to mom and dad's "Fatherland" (Arkansas) in January of 1969. I saw the ATSF Argentine Yard many, many times via 18th Street overpass as well as along the yard on side roads. (Can vividly remember Zerbra Stripe FM switchers switching in the yard among many other memories.)

As for this pic:

What I find the most interesting are the "lantern tracks" imprinted on the time exposure on the right side of the picture. Obviously, some cars and/or cuts of bled-off cars have been kicked or set against the previous cut, and the Brakeman had gone down the cut and laced-up the air hoses. The effect of the oil lantern swinging while walking as well as being used in-between the cars is fascinating.

Also, I'm wondering if that is an earlier version of the 18th Street overpass than was in my era? If so, then the position of the photographer and cars could be in the general location of what would become the massive Argentine Yard diesel locomotive servicing area. However, that picture may be further west and thus not the same area.

A couple of comments on the last two Shorpy photos:

  • The photo of the "part of the car shops" is the Rip Track,  where cars with en route defects are repaired, as well as some home road car repairs.  Rip stands for "Repair In Place" meaning the repair was not so serious that major work would be required.  Wrecks and frame failures, etc., had to go to the car shop.  If a car in a train in the yard was found to have a defect during the 500 mile train yard inspection, it would have been switched out of the train, sent to the Rip Track, and, after repair, would have been forwarded to destination in a later train.  Foreign road* car repairs were charged according to a manual published by the Association of American Railroads.  Home road cars were given periodic maintenance at the Rip Track.
  • In the Fort Madison (actually Shorten, IA) photo, the device mounted on the pilot truck frame of 4-6-2 3438 is the drive unit for the speed sensor of the cab signal system.  Santa Fe used cab signals (called Automatic Train Control by ATSF) between Fort Madison and Chicago.  The mechanical (hydraulic) speed recorder in the cab was normally driven by a cable drive from a small wheel resting on one of the drive wheels, or a cable drive off of a trailing truck axle.

*  Foreign road car:  Any car not owned by the railroad handling the car, in other words, all other railroads as well as private owner cars.
