This article is about rail service that is of a higher speed than conventional inter city rail. For high speed rail services with speeds more than 2. High speed rail. Higher speed rail Hr. SR1, also known as high performance rail,2higher performance rail,3 or almost high speed rail,4 is a jargon used to describe inter city passenger rail services that have top speeds of more than conventional rail but are not high enough to be called high speed rail services. The term is also used by planners to identify the incremental rail improvements to increase train speeds and reduce travel time as alternatives to larger efforts to create or expand the high speed rail networks. Some countries use the term medium speed rail, or semi high speed rail instead. DefinitionseditAs with the definitions of high speed rail, there is no universal definition of higher speed rail either. The term has been used by government agencies,9 government officials,1. Some countries with an established definition of higher speed rail include In Canada, according to the Surface Transportation Policy, Department of Transport, the speed range for higher speed rail is between 1. In India, according to the Minister of Railways, the speed range for Indias higher speed rail will be between 1. In Indonesia, the government is considering higher speed rail options, referred to as medium speed railway. The speed range is between 2. In the United Kingdom, the term higher speed rail is used for upgraded tracks with train speeds up to 1. In the United States, the term higher speed rail, as opposed to high speed rail, is used by regional planners in many U. S. states to describe inter city passenger rail services with top speeds of between 9. Railroad Pioneer Patch' title='Railroad Pioneer Patch' />This is the equivalent of the definition of Emerging High Speed Rail as defined by the Federal Railroad Administration. However, the Congressional Research Service defines Higher Speed Rail as rail services with speeds up to 1. Very High Speed Rail. State level departments of transportation and council of governments may use different definitions. Below is the list of known definitions of higher speed rail which use some of the 5 speed levels, 8. In Thailand, higher speed rail, which is called medium speed rail there, has top speeds of up to 2.

In the United States, railroad tracks are largely used for freight with at grade crossings. Passenger trains in many corridors run on shared tracks with freight trains. Most trains are limited to top speeds of 7. Federal Railroad Administration FRA. In developing higher speed rail services, one of those safety systems must be used. Additionally, the FRA establishes classification of track quality which regulates the speed limits of the trains with Class 5, Class 6, Class 7 and Class 8 for top speeds of 9. The FRA also regulates passenger train design and safety standards to ensure trains that operate at speeds of 8. Tier I standard and trains that operate at speeds up to 1. Tier II standard. Another limitation is the safety of grade crossings which limits how fast the trains can go. FRA regulations set speed limits for tracks with grade crossings as follows 3. For 1. 10 mph 1. Grade crossings are permitted. States and railroads cooperate to determine the needed warning devices, including passive crossbucks, flashing lights, two quadrant gates close only entering lanes of road, long gate arms, median barriers, and various combinations. Lights andor gates are activated by circuits wired to the track track circuits. For 1. 10 to 1. 25 mph 1. The FRA permits crossings only if an impenetrable barrier blocks highway traffic when a train approaches. Above 1. 25 mph 2. No crossings will be permitted. In Europe, the limit is often 1. In Sweden there is a special rule permitting 2. In Russia 2. 50 kmh 1. With the above limitations, many regional transportation planners focus on rail improvements to have the top speeds up to 1. Similar categorieseditIn countries where there had been rail improvement projects in the later part of the 2. Below are some examples of such services that are still in operation.

Higherspeed rail HrSR, also known as highperformance rail, higherperformance rail, or almosthighspeed rail, is a jargon used to describe intercity passenger. Europe The Inter. City services in many European countries have top speeds of mostly up to 1. Intercity trains that cross international borders are usually designated as Eurocity and reach similar speeds where tracks allow it. Japan The Mini shinkansen in Japan are upgraded lines from narrow gauge to allow Shinkansen to pass through with top speeds of 1. However, the International Union of Railways recognizes the Mini shinkansen lines as high speed rail. Spain Many inter city rail services operated by Renfe Operadora, the state owned company, are not classified as high speed rail. Those services are Alaris, Altaria, Arco and Talgo from Talgo III to Talgo VII with top speeds of 1. In Norway, there is sometimes talked about hy hastighet, which may be compared to higher speed rail as used here and hyhastighet, high speed rail. Most of the rail network is old, with sharp curves, and speeds at only 7. The lines around Oslo are upgraded or renewed, or are planned to be so. Some of the sections, like Follobanen OsloSki, 2. By the same token, the Norwegian FLIRT trains and the El 1. Gardermobanen is called a high speed line,4. GMB Class 7. 1 and NSB Class 7. However, the limits are blurry. Sometimes, e. g. the FLIRTs are called high speed trains. Sweden SJ Swedish Railways operates inter city rail services using X 2. The operator brands it as high speed rail services 4. International Union of Railways only recognizes the 3. Stockholm to Malm and Gteborg as the only high speed rail line in Sweden which is still in the planning stage. In Germany regional trains along the Munich Nuremberg high speed line which was built for 3. Those trains use locomotives that are used for Intercity trains elsewhere and the higher speed in comparison to other regional trains was chosen mainly to increase capacity. Commuter rail serviceseditSome commuter rail services that cover shorter distances may achieve similar speeds but they are not typically called as higher speed rail. Some examples are Rail improvement strategiesedit. Cab display unit of ACSES, an approved PTC system. There are many types of train that can support higher speed rail operation. Usually, the rail infrastructure needs to be upgraded prior to such operation. However, the requirements to the infrastructure signalling systems, curve radii, etc. But an upgrade to existing track currently in use, with busy traffic in some segments, introduces challenges associated with the construction work that could potentially disrupt the train services. The followings are some strategies used by regional transportation planners and rail track owners for their rail improvement projects in order to start the higher speed rail services. Signal upgradeseditIn Australia, the increased top speeds from 1. Regional Fast Rail project required a change to the signalling system to account for increased braking distance.
