20-460: The Michigan Interstate Railway ( reporting mark AA ) was formed on August 27, 1977, to operate the Ann Arbor Railroad main line from Toledo, Ohio , to Elberta, Michigan . It succeeded Conrail as the designated operator of the line; Conrail had operated the line since 1976, following the Ann Arbor Railroad 's bankruptcy. The Ann Arbor Railroad (1895–1976) had declared bankruptcy and

40-674: 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

60-461: 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

80-437: 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 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

100-685: 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

120-547: The U.S. Surface Transportation Board , Transport Canada , and Mexican Government. Railinc , a subsidiary of 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

140-504: 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

160-503: The MIRC assumed operations in 1977, the EMD GP35s were in a state of disrepair. The MIRC rebuilt eight of the EMD GP35s for service. Additionally, the MIRC also operated three ALCO S-3s , two ALCO RS-1s , and two ALCO RS-2s . 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

180-560: The MIRC from Toledo, Ohio to Ann Arbor, Michigan in September 1985. The MIRC continued to operate until October 7, 1988, when all assets were acquired by the Ann Arbor Acquisition Corporation . The Michigan Interstate Railway operated equipment that had been used by the previous operator, the Ann Arbor Railroad . The Ann Arbor Railroad purchased ten new EMD GP35s in 1962 that were built and delivered in 1963. When

200-657: 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

220-531: 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 ,

240-985: 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

260-448: 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

280-575: 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

300-557: 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

320-405: 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

340-727: 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

360-564: 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

380-408: Was included in the assets of Conrail , formed on April 1, 1976. The MIRC operated until October 7, 1988, when the Ann Arbor Acquisition Corporation acquired all assets. The Michigan Interstate Railway operated over the Ann Arbor Railroad main line from Toledo, Ohio to Elberta, Michigan . The MIRC assumed operations from Conrail on October 1, 1977, and operated until October 7, 1988. Elberta

400-509: Was the site of the railroad's ferry operations. The ferry operations ceased in April 1982 and service north of Cadillac, Michigan was reduced to a sand pit just south of Yuma, Michigan. Additionally, the Tuscola and Saginaw Bay Railway acquired operations north of Ann Arbor, Michigan in 1982. In 1983, the MIRC filed for reorganization and the trustee for the estate purchased the remaining portion of
