A reporting mark is an alphabetic code of two to four letters used to identify owners or lessees of rolling stock and other equipment used on certain rail transport networks.
In North America the mark, which consists of an alphabetic code of one 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 the railroad they are traveling over, which shares the information with other railroads and customers.
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.
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, 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 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 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 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 the 1990s, 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 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 a predecessor of the CNW, which passed it on to them, 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 the first letter of the reporting mark. Railinc, a subsidiary of the AAR, maintains the active reporting marks for the North American rail industry.
A railway vehicle must be registered in a national vehicle register (NVR) using a 12-digit number derived from the old UIC system of vehicle numbering. The number contains the register country in the third and fourth digit. The keeper of a vehicle is indicated with a company abbreviation of maximum five letters, called Vehicle Keeper Marking (VKM) which must be registered with OTIF and ERAand is unique throughout Europe and parts of Asia and Northern Africa. The VKM must not contain special signs or digits.
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 a hyphen. Some examples:
|B-B||Belgium||Société Nationale des Chemins de fer Belges|
|CH-SBB||Confoederatio Helvetica (Switzerland)||Schweizer Bundesbahnen|
|D-DB||Deutschland (Germany)||Deutsche Bahn AG|
|F-SNCF||France||Société nationale des chemins de fer français|
|I-FS||Italy||Ferrovie dello Stato Italiane|
|L-CFL||Luxembourg||Société Nationale des Chemins de Fer Luxembourgeois|
|TR-TCDD||Turkey||Türkiye Cumhuriyeti Devlet Demiryolları|
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.[ citation needed ]
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 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 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 the railways and registered with the Railway Clearing House.
In India, wagons owned by the Indian Railways are marked with codes of two to three 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 the railways and registered with the Ministry of Railways, Government of India.

Country codes are short alphabetic or numeric geographical codes (geocodes) developed to represent countries and dependent areas, for use in data processing and communications. Several different systems have been developed to do this. The term country code frequently refers to ISO 3166-1 alpha-2 or international dialing codes, the E.164 country calling codes.
A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.
The Association of American Railroads (AAR) is an industry trade group representing primarily the major freight railroads of North America. Amtrak and some regional commuter railroads are also members. Smaller freight railroads are typically represented by the American Short Line and Regional Railroad Association (ASLRRA), although some smaller railroads and railroad holding companies are also members of the AAR. The AAR also has two associate programs, and most associates are suppliers to the railroad industry.
A train reporting number in Great Britain identifies a particular train service. It consists of:
German vehicle registration plates indicate the place where the vehicle bearing them was once registered. Whenever German owners of a motor vehicle change their main place of residence within Germany or buy a car from a person living in a different city or district they have to have the vehicle documentation changed accordingly. In the process owners may opt for new licence plates that reflect their place of residence or simply retain the old identifier and plates. The states of Hesse, Schleswig-Holstein, Brandenburg, Saxony, Thuringia and North Rhine-Westphalia were the first ones to create laws so that owners were no longer obliged to change licence plates if they were changing residence within the state. A nationwide law has since been passed by the federal government and went into effect on 1 January 2015. From this time on, it is generally not possible any more to tell the owner's place of residence just from looking at the plates. Nonetheless it is a widespread habit in Germany, even a children's game when travelling, to guess "where that vehicle is from".
The Chicago and North Western Transportation Company was a Class I railroad in the Midwestern United States. It was also known as the "North Western". The railroad operated more than 5,000 miles (8,000 km) of track as of the turn of the 20th century, and over 12,000 miles (19,000 km) of track in seven states before retrenchment in the late 1970s. Until 1972, when the employees purchased the company, it was named the Chicago and North Western Railway.
ISO 6346 is an international standard covering the coding, identification and marking of intermodal (shipping) containers used within containerized intermodal freight transport. The standard establishes a visual identification system for every container that includes a unique serial number, the owner, a country code, a size, type and equipment category as well as any operational marks. The standard is managed by the International Container Bureau (BIC).
A number of different numbering and classification schemes have been used for carriages and wagons on Britain's railways, and this page explains the principal systems. Carriages and wagons have frequently had similar arrangements for classification and numbering, so are considered together. There are also links to other pages that deal in greater depth with the particulars of individual types.
A tank car is a type of railroad car or rolling stock designed to transport liquid and gaseous commodities.
Vehicle registration plates of Poland indicate the region of registration of the vehicle encoded in the number plate.
Originally, both Deutsche Bundesbahn and Deutsche Reichsbahn continued the classification system of the Deutsche Reichsbahn (DRG) – see also a short overview of the numbering system of the German railways. When UIC introduced a new classification system that could be processed by the computers of the late 1960s, DB did a major modification of their system, effective 1 January 1968. This system is still in use and now includes the engines of the former GDR railways as well.
A control car, cab car, control trailer, or driving trailer is a generic term for a non-powered railroad (US) or railway (UIC) vehicle that can control operation of a train at the end, opposite to the position of the locomotive. They can be used with diesel or electric motive power, allowing push-pull operation without the use of an additional locomotive. They can also be used with a power car or a railcar. In a few cases control cars were used with steam locomotives, especially in Germany and France.
For more than a century, the Swiss locomotive, multiple unit, motor coach and railcar classification system, in either its original or updated forms, has been used to name and classify the rolling stock operated on the railways of Switzerland. It started out as a uniform system for the classification and naming of all rolling stock, powered and unpowered, but had been replaced and amended by the UIC classification of goods wagons.
Goods wagons or freight wagons, also known as goods carriages, goods trucks, freight carriages or freight trucks, are unpowered railway vehicles that are used for the transportation of cargo. A variety of wagon types are in use to handle different types of goods, but all goods wagons in a regional network typically have standardized couplers and other fittings, such as hoses for air brakes, allowing different wagon types to be assembled into trains. For tracking and identification purposes, goods wagons are generally assigned a unique identifier, typically a UIC wagon number, or in North America, a company reporting mark plus a company specific serial number.
This list contains the UIC classification of goods wagons and their meanings. The description is made up of a category letter and usually several index letters.
The UIC identification marking for tractive stock is a standard for identifying train stock like locomotives that supply tractive force. Since the beginning of 2007 locomotives or other traction units in Europe have been given a 12-digit number. Vehicle numbering is now governed by the Intergovernmental Organisation for International Carriage by Rail and in Technical Specifications for Interoperability (TSI) of the European Union, specifically the European Railway Agency's CR OPE TSI. This makes the locomotive clearly identifiable within Europe and parts of Asia and northern Africa.
Wagon numbers are key data for railway operations. They enable a railway wagon or coach to be positively identified and form a common language between railway operators, infrastructure companies and the state authorities. The system of wagon numbering has been laid down by the International Union of Railways and is similar to that used for the locomotives and multiple units. Vehicle numbering is now governed by the Intergovernmental Organisation for International Carriage by Rail and in Technical Specifications for Interoperability (TSI) of the European Union.
Railinc Corporation provides rail data and messaging services to the North American freight railway industry. Railinc is a for-profit subsidiary of the Association of American Railroads.
KarTrak, sometimes KarTrak ACI(for Automatic Car Identification) is a colored bar code system designed to automatically identify rail cars and other rolling stock. KarTrak was made a requirement in North America, but technical problems led to abandonment of the system in the late 1970s.
