  • Class 1: RST having max speed of at least 250 km/h
  • Class 2: RST having a max speed of at least 190 km/h
  • But less than 250 km/h
  • Technical standard exists for 190 to 350 km/h
  • Over 351 km/h technical requirements down to supplier
  • Authorisation only for trains up to 350 km/h
  • Articulated v/s Non-articulated

Definition of High Speed RST

slide-21
SLIDE 21

21

  • Long headway
  • High distance between stations
  • Braking distance
  • Seats for all occupants
  • Train management systems
  • Interface with infrastructure tunnels etal
  • Track layout

HS2 Technology

  • 1. Utilising existing proven technology

2.Capacity 18 trains per hour 3.Design speed of 250 mph (400 km/h) 4.Limited hours of operation 5.Dynamic gauge 6.Specify classic compatible trains

slide-27
SLIDE 27

HS2 Technology

  • 7. Reliability
  • 8. Impact on other rail services
  • 9. Freight on HS2

10.Interconnectivity

  • 11. Operational safety
slide-28
SLIDE 28

Utilising existing proven technology

  • 1. Technical Specification
  • 2. Internationally accepted practice
  • 3. Established European standards
  • 4. Unproven technology

Design speed

  • 1. Designed to accommodate future speeds

2.Up to 250mph (400 km/h) 3.Phase 1 operation up to 225 mph ( 360 km/h)

slide-31
SLIDE 31

Limited hours of operation

  • 1. 05:00 to 23:59 hours Monday to Saturday

2.08:00 to 23:59 hours on Sunday 3.No trains during the night?

slide-32
SLIDE 32

Dynamic gauge

  • 1. New track GC gauge

2.Upgrade the existing network 3.Single and Double deck trains 4.Utilise existing European proven RST 5.In line with HS1 6.CrossRail?

slide-33
SLIDE 33

Classic compatible trains

  • 1. Move passenger traffic from the existing routes

2.Free up urban capacity on existing routes 3.Move some existing intercity trains to HS2 4.Slow down HS2? 5.No freight 6.High speed freight

slide-34
SLIDE 34

Reliability

  • 1. Segregated HS networks more reliable

2.Example Japan 3.Services moved from existing routes less reliable 4.Import poor reliability 5.Confine route transfer to outside core times

slide-35
SLIDE 35

Impact on other rail services

  • 1. Diversion of long distance services

2.Free up capacity on WCML 3.Improve commuter traffic 4.London to Birmingham 5.Better links with other services 6.Increase freight capacity

slide-36
SLIDE 36

Freight on HS2

  • 1. In principle no freight

2.Problem where HS2 will use existing upgraded routes 3.Address the issue left by Beeching 4.Re-establish multi-tracking

Interconnectivity

  • 1. Careful planning of interchanges

2.East Midlands Interchange 3.Crewe 4.Birmingham

slide-40
SLIDE 40

Operational safety

  • 1. Dedicated two track HS passenger route

2.Continuous train movement monitoring 3.Continuous Train to Controller communication 4.Continuous infrastructure monitoring 5.Security fencing 6.Design bridges to prevent vehicular incursion 7.Regular inspection of RST and track

HS2 Ltd has named its chosen contractors for the construction of the London to Birmingham high speed rail line. Among the winners are the CEK joint venture of Carillion, Eiffage, Kier, which has been awarded two lots that are together worth a keenly bid £1.4bn, and Balfour Beatty Vinci JV which has also won two lots, together worth £2.5bn The other big winner is SCS JV (Skanska Construction UK, Costain, Strabag), which has won two lots of tunnelling under London. Half of the contactors involved in the project are foreign owned.

SLIDE 52

Discussion points

  • 1. Is a ground up HS railway on a new site the right thing?
  • 2. Is there a viable option of upgrading the existing route?
  • 3. Should freight be given access?
  • 4. Is a dedicated HS railway necessary in either Brazil or UK?
  • 5. Is it ethical to plan for a VHS train with no technical standards?
