Below is a glossary for the SCRS tool.


CIF Number:  Customer Information File Number


The CIF number is the 13 character, Rail Industry Customer Identification Number assigned to a company name and industrial street address in the city, state or province where it is physically located (not the headquarters or invoicing location unless it is the same as the physical address). The CIF consists of 9-digit D&B D-U-N-S ® Number for that location followed by four (4) zeros. If instead of 4 zeros, the 9-digits are followed by another numeric suffix, that suffix identifies a sub-location within the primary location.


There are 3 types of sub-locations:

• Bill to Address 7000 series suffix: in addition to a physical or primary Post Office Box address, many customers have Post Office Box or Attention addresses exclusively for freight bills.

• Delivery to Address 8000 series suffix: specific railcar delivery information such as lease track or team track locations, and Zone Track Spots (ZTS).

• Doing Business As or DBA Name 9000 series suffix: names registered as other than the legal company name under which a company conducts business.


The CIF number is the data key to the SCRS file. Only the number resides in SCRS with links to the CIF Industry Reference File for the customer name and address information.


Reciprocal Switching:

• The term “reciprocal switching” is the movement of a railcar, in switch service between the interchange tracks of one railroad to a customer’s private or assigned siding on another railroad for the purpose of loading or unloading freight. The service precedes or follows a road haul and is bi-directional to include both the loaded and empty railcar.


SCRS:  Serving Carrier Reciprocal Switch


Switch District:  Is a predefined group of stations encompassing major metropolitan cities and the outlying urban area (switch district) where rail service is performed and priced between the locations the same as if performed wholly within the city limits; I.E: e.g., Wood Street Yard is within the Chicago switch district.


Switch Status Definitions:

Closed:  Freight station is commonly served (2 or more Railroads).  Serving Railroad does not perform reciprocal switching and gets line haul.

Local:  Freight station is served exclusively by one railroad.  Serving Railroad gets line haul revenue.

Open:  Freight station is commonly served (2 or more Railroads).  Serving Railroad performs reciprocal switching.

Restricted:  Freight station is commonly served (2 or more Railroads).  Serving road performs reciprocal switching under specified conditions.
