What is High Speed Rail?
High Speed Rail:
Inter City or Inter Regional Travel at >250kph (>150mph); typically 300 to 350 kph (180-210mph)
High Frequency; ca. 10 trains per hour, per direction
High Density; > 500 – 750 seats per train
Central Manchester – Central London in under 80 minutes! Not possible by car, conventional rail or air.
What is High Speed Rail?
There is no internationally agreed definition of what constitutes a high speed railway (HSR)
EU directive on interoperability defines HS rail as routes operating at > 200 km/h (125 mph)
Typical speeds for HSR elsewhere are 300 km/h or greater
High speed railways do tend to share certain characteristics including:
New or substantially upgraded infrastructure
Wide minimum track radius to allow high speeds
Wide spacing between tracks to reduce air pressure between passing trains
No level crossings
High Speed Rail in the UK
The UK’s only HSR route is the channel tunnel rail link (now known as High Speed 1), which consists of:
109 Km long new high speed route
3 major tunnel sections totalling 25 Km
High Speed 1 – Medway Viaduct
High Speed 1 (CTRL)
London – Paris (via Tunnel) 135 min
1998 - 2007
