High-availability Seamless Redundancy. High-availability Seamless Redundancy ( HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite.
High-speed rail (HSR) is a type of rail transport network utilizing trains that run significantly faster than those of traditional rail, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above 250 km/h (155 mph) or upgraded lines ...
HSL 1 connects Brussels with the French border. 88 km (55 mi) long (71 km (44 mi) dedicated high-speed tracks, 17 km (11 mi) modernised lines), it began service on 14 December 1997.
The Direttissima opened in 1977 as the first high-speed rail route in Italy and Europe, connecting Rome with Florence.The top speed on the line was 250 km/h (160 mph), giving an end-to-end journey time of about 90 minutes with an average speed of 200 km/h (120 mph).

UCI race classifications. The Union Cycliste Internationale ( UCI ), the world's governing body in the sport of bicycle racing, classifies races according to a rating scale. The rating is represented by a code made of two or three parts and indicates both the type or style of race (the first part), and its importance or difficulty (the second ...
Since HSR in Denmark is reaches no more than 200 km/h, it can also be described as higher-speed rail. As a part of a long-term green plan for transportation in Denmark in December 2008, the government at the time presented a high-speed strategy for the inter-city train traffic, called The Hour Model ( Danish : Timemodellen ).
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1] The abstract data models defined in IEC 61850 can be mapped to a ...
