Railroads reporting using computer-based realtime car control
Comments by railroads on success of using realtime car control, with reference to changes made since 1967
GN uses computer for
optimizing car control GN, with
car-control well established, describes how they use the computer to optimize terminal operations and car supply.
Mentions use of UNIVAC 1 in 1957.
Uses of Computers
for engineering by railroads, 1959
Assignment 4, Committee Report, Economics Of Railway Location and Operation.
Includes long lists of computer-types then
currently in use.
SCL's car tracking system, and proposal to expand with car control
Describes SCL computer-based car-tracking system, using 70 terminals (55 in yards) communicating to central 360/40 computer.
Describes proposed (car) control loop functions.
Siding numbers (zone-track), first used by PRR in 1927
Also lists PRR Chicago area siding numbers by Zone and Customer, for 1956 revision
Yard Operations car routing data flow
From C&O, 1969: How advance lists become switchlists, and how waybills are handled in a yard.

Note that Conrail uses a paired 2-digit 'from' 'to' format for track spots. The numbers are ##zone-###track-##from-##to

- This map is more typical as it is on one page.
The symbols along the track, lines plus circles, denote spots

Examples on multiple spots on a single spur. See the topmost three spurs on this map. The boxes with "0#" numbers in the outlines of the structures mark the spots.
The customers' buildings face two adajcent streets and the spur runs down the backyard.

- General Instructions page 3 Maintaining Sequence Check, Repetitive Information
- General Instructions page 4 Returning Switchlists, Adding work to switchlists
- Yard Procedures Reporting Work Complete, If Switching not complete. Note emphasis on reporting work done and train "standing order integrity" - the order of the cars in a train
- Industrial Switching page 1 Cars spotted and pulled, Constructive Placement
- Industrial Switching page 2 Cars not spotted, Plant switching, One car for two customers
- Industrial Switching page 3 Loads/empties left in storage track, Cars not on Switchlist
- Industrial Switching page 4 Cars left for furtherance, cont'd
Car Quality Card Card stapled to car after inspection
- Cars (kinds: X, R and G) are inspected following Interchange Rule 1, and graded into one of 5
A, B, C, K
(contaminated) and U (condemned), plus D for gondola cars.
- in current era N and W also are used
Dirty cars (containing refuse and not yet cleaned) otherwise graded A, B, C are graded X, Y, Z until cleaned. Send these cars to your car cleaning facility.
You can model car grading, and car cleaning, with manual car-tracking (see photo above) but a computer system makes this a snap.
Here is an excuse for more boxcars (Fleets for "A" and "K" commodities).
This CR car was carrying brick into Ontario from Tennessee in 1988.
