CLIC, SPINS, ZTS: Zones, Tracks, Spots identification
please notice: this is a draft Version V0.2 (Status: 2010-07-28).
Please tell me about errors, and additions needed. I will update this site, and I hope the final version is one that a model railroader can use to set up a system to support the operations of his/her model railroad. At least, I will do so.
I got information about the systems from sources in USA and Germany, mostly from LDJ Layout Design Journal of the LDSIG, discussion groups in yahoo, and documents of Santa Fe and Conrail.
What I did:
I took the track plan of my model railroad yard "Chatteris, NE", and added the information regarding the CLIC, SPINS and ZTS systems. Please remember: I put in the information I got so far, and I think that there are errors in this draft!
and the data:
CLIC = Car Location Identity Code
Maps on CLIC documents are not drawn to scale and are to be used only as a guide to locating customers and yard tracks and the numbers assigned to them.
The geographical area covered in CLIC booklets is divided into Zones. Each Zone has designated tracks and/or industries within its boundary.
A CLIC number will consist of six digits. The first two digits designate a Zone, the seond two digits indicate the Track number within the zone; the last two digits represent the actual Spot along the track.
The combination of the Track-Zone-Spot number is known as the "Car Location Identity Code" (CLIC).
The "CLIC" number will be used for switching and reporting purposes rather than the industry or track name.
**Example of CLIC number**
All switch targets or stands have been painted with a combination of the Zone and Track number.
Spot numbers have been paintd on doors, docks, buildings, gates, etc., wherever possible.

in SPINS, it looks different:
Details of SPINS:
SPINS is the "Southern Pacific Industrial Numbering System”.
SPINS books identify industries and switching zones, tracks and consignee loading and unloading spots. By giving Zones, Tracks and Spots certain designated numbers, the railroad was able to print switch lists with exact locations to which a customer's car is to be spotted. A SPINS number contains six digits:
**Example of SPINS number**
Track numbering of Spots begins at (the first) turnout.
In the example of the track plan of Chatteris (see above), track 2710 begins at switch 2710. The grain elevators are at track 2710, as the switches 2711 and 2712 lead to diverging tracks 2711 and 2712, while 2710 is the one following the track in a "normal" switching position.
Zone and Track numbers appear on the switch targets. At parallel tracks as 2701, the 2701 appears at both switches, at both ends.
Spot signs are placed where a customer normally loads or unloads their cars. Spot sings are 6" x 6" green metal signs with 4" white reflectorized numbers. These are placed at the center of a car spot. In other locations, spot numbers may be painted on customer loading doors or other structures.

another system, looking different:
and the data:
Details of ZTS:
ZTS is the system of Union Pacific, Conrail and others. It is called "Zone-Track-Spot”
