The rail industry istypically segmented into the following categories: rolling stock (trainsets),infrastructure (components, rails, installation, etc.), rail signaling or traincontrol, and services. Rolling stock industry is further segmented into trains,locomotives, and wagons. Basically, rolling stock and locomotives comprises allthe vehicles that move on a railway track. There is a wide range of types ofrolling stock, which can be broken down in various segments:This report segmentsthe type of trains serviced by the following categories: high speed/very highspeed (VHS), mainlines, light rail, metro/subway, freight, andindustrial/mining.
While definitions vary by geography, high-speed trainstypically operate at 200 to 250 km/hour and VHS trains range from 300 to 350km/hour. Mainlines are traditional rolling stock and infra-structure operations,typically used for passengers but may also be used for freight. (Very) highspeed trains run at speeds of at least 220 km/h. The trains can consist ofmultiple units or can be a single carriage, with a driver’s cab at one or bothends.Light rail or lightrail transit is a form of urban/suburban rail public transportation thatgenerally has a lower capacity and lower speed than heavy rail and metrosystems. The metro/subway category includes rapid transit, underground, subway,elevated railway, and metro railway systems with a high capacity and frequency.These systems are typically located in underground tunnels, on elevated railsabove street level, or outside urban centers, or they may run on grade separatedground level tracks.Multiple units areself-propelled rail cars, without locomotives, carriages coupled together and arecontrolled by one driving train set.
Multiple units are classified based on thesource of power they need to function; electric multiple unit (EMU) or dieselmultiple unit (DMU). They are primarily used for passenger transport. Sometimesa further differentiation is based on speed and/or the type of lines they serve(eg. Intercity, regional, local).
Wagons are passenger railway vehicles otherthan passenger railcars, and include sleeping cars, saloon cars, dining cars,etc. Freight wagons are railway vehicles intended for transport of goodsconnected to locomotive to pull the set of wagons.Locomotives provide themain power for a train movement along the tracks.
Newly designed metros areself-propelled trainsets which do not need separate locomotive. A furtherclassification of locomotives is based on their power source, mainly diesel orelectricity.The freight category isused to separate solutions specifically targeted for freight, not passenger,operations. The industrial/mining category is a burgeoning one characterized bylower speed requirements, a tendency to look beyond conventional signaling dueto maintenance and other issues, and a rising interest in driverless operation.The research alsosegments the market based on geography. The four segmentations are NorthAmerica; Europe, Middle East, and Africa; Asia Pacific; and South America.
