A reporting mark is a code used to identify owners or lessees of rolling stock and other equipment used on certain rail transport networks. The code typically reflects the name or identifying number of the owner, lessee, or operator of the equipment, similar to IATA airline designators .

29-456: The Modoc Northern Railroad ( reporting mark MNRR ) is a defunct railroad company that operated over 160 miles (260 km) of track in northeastern California and southern Oregon and was based in Tulelake, California . The railroad connected Klamath Falls to Alturas, California , and Lakeview, Oregon , to Alturas, California . The railroad shipped mostly timber products and some perlite from

58-674: A 2-digit code indicating the vehicle's register country . The registered keeper of a vehicle is now indicated by a separate Vehicle Keeper Marking (VKM), usually the name of the owning company or an abbreviation thereof, which must be registered with the Intergovernmental Organisation for International Carriage by Rail (OTIF) and the European Union Agency for Railways (ERA) and which is unique throughout Europe and parts of Asia and Northern Africa. The VKM must be between two and five letters in length and can use any of

87-473: A check digit calculator is programmed. Virtually all programming languages have a modulo operator for step 3; some languages (also) return the decimal portion which must be multiplied by 11 to get a proper modulo. 11 is used as divisor because a container number has 11 letters and digits in total. In step 1 the numbers 11, 22 and 33 are left out as they are multiples of the divisor. In day-to-day business it happens that containers do appear which do not follow

116-461: A hyphen. Some examples: When a vehicle is sold it will not normally be transferred to another register. The Czech railways bought large numbers of coaches from ÖBB. The number remained the same but the VKM changed from A-ÖBB to A-ČD. The UIC introduced a uniform numbering system for their members based on a 12-digit number, largely known as UIC number . The third and fourth digit of the number indicated

145-685: A predecessor of the CNW, from which the UP inherited it. Similarly, during the breakup of Conrail , the long-retired marks of the Pennsylvania Railroad (PRR) and New York Central Railroad (NYC) were temporarily brought back and applied to much of Conrail's fleet to signify which cars and locomotives were to go to CSX (all cars labeled NYC) and which to Norfolk Southern (all cars labeled PRR). Some of these cars still retain their temporary NYC marks. Because of its size, this list has been split into subpages based on

174-510: A unique serial number (with check digit ), the owner, a country code, a size, type and equipment category as well as any operational marks. The register of container owners is managed by the International Container Bureau (BIC). Example of an ISO 6346 compliant container number: [REDACTED] The illustrated example is a code for a container owned by Hapag-Lloyd AG . The owner code consists of three capital letters of

203-493: Is multiplied by 2 , where position is the exponent to base 2. Position starts at 0, from left to right. The following table shows the multiplication factors: If the final difference is 10, then the check digit becomes 0. To ensure that this does not happen the standard recommends that serial numbers should not be used which produce a final difference of 10; however, there are containers in the market which do not follow this recommendation, so handling this case has to be included if

232-611: Is standard, reefer...) The equipment category identifier consists of one of the following capital letters of the Latin alphabet: Presently, all official BIC container codes end in "U". However, the Association of American Railroads recognizes similar codes for their containers and trailers travelling by rail in North America, though these are not recognized by the BIC and lack check digits. Under

261-643: The TTX Company (formerly Trailer Train Company) is named for its original reporting mark of TTX. In another example, the reporting mark for state-funded Amtrak services in California is CDTX (whereas the usual Amtrak mark is AMTK) because the state transportation agency ( Caltrans ) owns the equipment used in these services. This may also apply to commuter rail, for example Metrolink in Southern California uses

290-504: The 26 letters of the Latin alphabet . Diacritical marks may also be used, but they are ignored in data processing (for example, Ö is treated as though it is O ). The VKM is preceded by the code for the country (according to the alphabetical coding system described in Appendix 4 to the 1949 convention and Article 45(4) of the 1968 convention on road traffic), where the vehicle is registered and

319-558: The AAR, maintains the active reporting marks for the North American rail industry. Under current practice, the first letter must match the initial letter of the railroad name. As it also acts as a Standard Carrier Alpha Code , the reporting mark cannot conflict with codes in use by other nonrail carriers. Marks ending with the letter "X" are assigned to companies or individuals who own railcars, but are not operating railroads; for example,

348-542: The ISO 6346 identification at all; however, they are fully CSC safety approved containers. Usually these are "shippers owned" containers (SOC), which means that they are not owned by the carrier but supplied by the cargo owners (shippers). They may have no registered owner code and no category identifier and have no check digit. It is advisable to follow ISO 6346 as the absence of a compliant identification code causes problems for both carriers and container terminals to correctly identify

377-409: The ISO code, then, only U, J, and Z are in use. The refrigerated (reefer) container is identified by means of the size type code. The serial number consists of 6 numeric digits, assigned by the owner or operator, uniquely identifying the container within that owner/operator's fleet. The check digit consists of one numeric digit providing a means of validating the recording and transmission accuracy of

406-611: The Lake County Railway, connecting Alturas to Lakeview, in 2006. UP cancelled the lease on May 5, 2009, and a new operator has assumed control of the Lake County Railroad . Reporting mark In North America , the mark, which consists of an alphabetic code of two to four letters, is stenciled on each piece of equipment, along with a one- to six-digit number. This information is used to uniquely identify every such rail car or locomotive, thus allowing it to be tracked by

435-527: The Latin alphabet to indicate the owner or principal operator of the container. Such code needs to be registered at the Bureau International des Containers in Paris to ensure uniqueness worldwide. An owner can apply for more than one code, as normally the first 2 letters are used as the owner code and the third is used to indicate pool (e.g. HLA, HLB, HLX are some Hapag-Lloyd codes to indicate whether container

464-657: The VKM BLS. Example for an "Einheitswagen" delivered in 1957: In the United Kingdom, prior to nationalisation, wagons owned by the major railways were marked with codes of two to four letters, these codes normally being the initials of the railway concerned; for example, wagons of the Great Western Railway were marked "G W"; those of the London, Midland and Scottish Railway were marked "L M S", etc. The codes were agreed between

493-531: The acquiring company discontinues the name or mark of the acquired company, the discontinued mark is referred to as a "fallen flag" railway. Occasionally, long-disused marks are suddenly revived by the companies which now own them. For example, in recent years, the Union Pacific Railroad has begun to use the mark CMO on newly built covered hoppers, gondolas and five-bay coal hoppers. CMO originally belonged to Chicago, St. Paul, Minneapolis and Omaha Railway ,

522-488: The equipment and properly deliver the cargo, because computer systems require ISO 6346-conforming naming and as such missing prefixes are invented. For example, YYYY at the carrier and XXXX at the terminal causes the equipment to mismatch. Moreover, since ISO 6346 identification has become a requirement in international Customs conventions (Customs Conventions on Containers and Istanbul Convention), many Customs Administrations have begun validating that containers are marked as per

551-448: The first letter of the reporting mark: A railway vehicle must be registered in the relevant state's National Vehicle Register (NVR), as part of which process it will be assigned a 12-digit European Vehicle Number (EVN). The EVN schema is essentially the same as that used by the earlier UIC numbering systems for tractive vehicles and wagons , except that it replaces the 2-digit vehicle owner's code (see § Europe 1964 to 2005 ) with

580-734: The mine and mill near Lakeview. The rails used by the Modoc Northern were first laid out in June 1927 by a non-operating subsidiary of the Southern Pacific Company with the same name. On November 1, 2005, Union Pacific Railroad leased the Modoc line, connecting Klamath Falls to Alturas, to the MNRR for five years. By request of the Lake County, Oregon, commissioners, the MNRR also took over operation of

609-402: The owner code and serial number. To compute the check digit, the letters have to be converted to numbers. This is done in three steps: An equivalent numerical value is assigned to each letter of the alphabet, beginning with 10 for the letter A (11 and multiples thereof are omitted): The individual digits of the serial number keep their numeric value. Each of the numbers calculated in step 1

638-557: The owner of a reporting mark is taken over by another company, the old mark becomes the property of the new company. For example, when the Union Pacific Railroad (mark UP) acquired the Chicago and North Western Railway (mark CNW) in 1995, it retained the CNW mark rather than immediately repaint all acquired equipment. Some companies own several marks that are used to identify different classes of cars, such as boxcars or gondolas. If

667-405: The owner, or more precisely the keeper of the vehicle. Thus each UIC member got a two-digit owner code . With the introduction of national vehicle registers this code became a country code. Some vehicles had to be renumbered as a consequence. The Swiss company BLS Lötschbergbahn had the owner code 63. When their vehicles were registered, they got numbers with the country code 85 for Switzerland and

696-406: The railroad it is traveling over, which shares the information with other railroads and customers. In multinational registries, a code indicating the home country may also be included. The Association of American Railroads (AAR) assigns marks to all carriers, under authority granted by the U.S. Surface Transportation Board , Transport Canada , and Mexican Government. Railinc , a subsidiary of

725-565: The railways and registered with the Ministry of Railways , Government of India . ISO 6346 ISO 6346 is an international standard covering the coding, identification and marking of intermodal (shipping) containers used within containerized intermodal freight transport by the International Organization for Standardization (ISO). The standard establishes a visual identification system for every container that includes

754-727: The railways and registered with the Railway Clearing House . In India, wagons owned by the Indian Railways are marked with codes of two to four letters, these codes normally being the initials of the railway divisions concerned along with the Hindi abbreviation; for example, trains of the Western Railway zone are marked "WR" and "प रे"; those of the Central Railway zone are marked "CR" and "मध्य", etc. The codes are agreed between

783-794: The reporting mark SCAX because the equipment is owned by the Southern California Regional Rail Authority —which owns the Metrolink system—even though it is operated by Amtrak. This is why the reporting mark for CSX Transportation , which is an operating railroad, is CSXT instead of CSX. Private (non-common carrier) freight car owners in Mexico were issued, up until around 1990, reporting marks ending in two X's, possibly to signify that their cars followed different regulations (such as bans on friction bearing trucks) than their American counterparts and so their viability for interchange service

812-456: The standard. The codes are compiled of the following elements: The following is an overview of the most common codes: Use the below to calculate size/type of a less commonly used ISO 6346 containers: The country code consists of two capital letters of the Latin alphabet as described in ISO 3166-1 . It indicates the country where the code is registered not the nationality of the owner or operator of

841-564: Was impaired. This often resulted in five-letter reporting marks, an option not otherwise allowed by the AAR. Companies owning trailers used in trailer-on-flatcar service are assigned marks ending with the letter "Z", and the National Motor Freight Traffic Association , which maintains the list of Standard Carrier Alpha Codes, assigns marks ending in "U" to owners of intermodal containers . The standard ISO 6346 covers identifiers for intermodal containers. When
