1 South Yorkshire I Mech E, Sheffield, 3 October 2013 High Speed 2- engineering, benefits & challenges Prof Roderick A Smith Chief Scientific Advisor Department for Transport & Imperial College London

2 Lecture Outline: 1. Introduction: transport past, present, future 2. Government & DfT plans 3. About HS2 4. Concluding remarks

3 1. Introduction The role of and importance of transport in our lives Brief history of transport in the UK Key future challenges: Demand Capacity Carbon Consequences of climate change

4 UK transport use per capita Freight: 3500 tonne km year 10 tonne km / day Plus one overseas trip each year, 80% by air 12,500 km / year 34.4 km / day By what mode? % km / day Bus, coach Cycle Motor cycle Car, taxi Rail Air 8 2.8

5 km built in previous decade Transport infrastructure build Turnpikes Canals Railways City trams Trunk roads Motorways Year

7 Development of traction Horse, steam, electric Urban Trams

8 When motorway driving was a pleasure!

10 The Buchanan Report 1963 (traffic) conditions as they are going to develop in this island [Britain] will demand an almost heroic act of self-discipline from the public. Motor manufacturers, parents and teachers will have major parts to play, but the main burden of responsibility will rest with drivers.

12 Demand Capacity DEmand Carbon

13 2 Government & DfT plans Further investment in roads Greening of cars, & encouraging mode switch Greater airport capacity New high speed rail system

17 Airports Commission Making sure UK airports and airlines are safe, secure and competitive while reducing their impacts on the environment and communities

18 3 About High Speed 2 What is it? Key engineering features Transformational possibilities Challenges Properly integrated system plans Time scales and costs Winning hearts & minds

33 HS2 Summary Programme 2013 Public consultation on preferred route and station options for Phase Two High Speed Rail Preparation Bill, giving the government powers to spend money on preparatory work for the railway, to receive full parliamentary approval ( Royal Assent ) Phase 1 Hybrid Bill introduced to Parliament, containing legal powers to construct and operate Phase 1 of HS Government decision on Phase Two route and station options Hybrid Bill process continues 2015 Commence engineering design, environmental impact assessment and preparation for Phase 2 Hybrid Bill Next Parliament Target date for full parliamentary approval ( Royal Assent ) of Phase 1 Hybrid Bill Phase 2 Hybrid Bill introduced to Parliament 2016/17 Construction of Phase 1 commences Late 2010s Mid 2020s Procurement of rolling stock Construction of Phase 2 commences 2026 Phase 1 line opens 2032/33 Phase 2 line opens

35 Some of the myths: HS2 will: use too much energy be a rich man s toy guarantee economic growth in the future only serves the end points diminishes the existing railway must go to existing city centres destroy huge swaths of countryside and anyway, Britain's geography is wrong

37 A 21 st Century Railway: The Passenger Experience High capacity: up to 18 trains per hour, up to 1100 seats per train Intelligent ticketing High quality comfort and access to trains and stations Good connections: end-to-end journeys 37

38 Rural Relative cost Between A & B the line to the core is at least twice as long, on (much) more expensive land, and with smaller radii 8 A Suburbs Inner city Core New HS Station is the focal point for new development and a new transport hub An escape for the constraints of the past B Distance ratios: 6 4 1
