When to invest in High Speed Rail Chris Nash C.A.Nash@its.leeds.ac.uk
Outline • Motivation behind high speed rail investment • Costs and benefits of high speed rail • Examples of appraisals – ex ante and ex post • What alternatives should be considered? • Conclusions
Origins (new lines 250km per hour or more) 1964 Tokaido Line 1981 Paris-Lyon 1981 Rome-Florence (1st section) 1988 Fulda-Wurzberg 1992 Madrid-Seville 2013 European total 7378km (Spain 2515; France 2036) World 21472 km (China 9867; Japan 2664) Source: UIC
Motivation for HSR • Speed • Capacity • Reliability • Economic Development • Environment • Supply industries • Prestige • Political integration
Costs and Benefits COSTS • Capital costs • Net Operating costs • Net External costs (environment, safety) • Loss of tax revenue BENEFITS • Revenue • Time savings and improved reliability • Additional capacity; reduced crowding and diversion from other modes • Diversion from other modes (reducing congestion and environmental impact) • Generated traffic • Wider economic benefits
Typical costs of HSR in Europe (m2004 euros) Capital costs Infrastructure Construction (per km) 12-40 Construction costs vary enormously with the terrain (especially length of tunnels) and the degree to which new lines and stations in cigties are needed. Operating costs depend mainly on rolling stock requirements, staff, energy, wear and tear – note very high utilisation of assets may offset high energy and maintenance costs
Time savings • Most of the benefits time or time related (crowding, reliability) • Most of them relate to business travel • Usually based on cost savings approach (wage rate plus overheads) • New work based on willingness to pay puts values up! • Can fit more meetings into a day • Avoids travel in (very) unsocial hours

Capacity benefits • Increased traffic on hsr route • Increased traffic on other routes • Reduced overcrowding • Improved reliability
Benefits of diversion from car or air • Reduced congestion • Environmental pollution • Accidents • Release of airport capacity for long distance flights
Generated traffic(valued at half the benefits to existing traffic) • Leisure • Commuting • Business Does this reflect relocation of business or net expansion?
Wider economic impacts Current evidence relates mainly to major conurbations - Agglomeration benefits - Labour market benefits • Imperfect competition Are there also benefits from improving inter city connections? Venables, Overman and Laird – specialisation and economies of scale KPMG – correlation between productivity and rail connectivity, but does this imply causation? Should a LUTI model be developed to examine locational implications and further agglomeration?

CBA of Madrid-Seville high-speed rail in Spain (billions of 2010 euros) Demand in 1993 2.8m trips
CBA of Madrid-Barcelona high-speed rail in Spain (billions of 2010 euros) Demand in 2009 5.5m trips
sH2HS2w? HS2 New high speed line from London to Birmingham, Manchester and Leeds (with trains running on to Newcastle, Glasgow ands Edinburgh) Objectives • to provide sufficient capacity to meet long term demand, and to improve resilience and reliability across the network; and • to improve connectivity by delivering better journey times and making travel easier. • Economic regeneration and reducing the North-South divide • Reducing greenhouse gases
Forecasting demand • Will long run trend favouring rail continue? • Impact of improvements in telecommunications • Autonomous cars • Range of scenarios
Examples of Network Rail forecast growth over 30 years London to: Birmingham 33-87% Manchester 52-158% Leeds 46-123% Birmingham to Manchester 39-117% Leeds 40-126%
Diversion from other modes HS2 patronage is forecast to be: 69% diverted from conventional rail 26% induced 4% from car 1% from air But released capacity on conventional lines may permit more diversion including freight from road.
Current government pricing policy • Rail fares rise by 1% per annum from 2020 (25% by 2036) • HSR fares to be same as conventional rail • But the only sensible pricing policy for HSR is yield management • Threat of open access competition • Motoring costs fall by 40% by 2036 • Air fares fall by 30% by 2036. Should alternative pricing policies be explored? Are they really a matter of overall land use transport strategy
Range of options considered First British domestic HSR study – Atkins 2002 Options considered: • Different routes • New conventional line • Timing • Pricing • Road and air investment
Figure 1.1 The Atkins study in Britain- results
HS2 alternatives examined • Alternative routes • Longer trains • Upgrading of existing lines • 51M proposals But not Is infrastructure suitable for 400km (and actual 360kmph running) needed?
Table 13 Incremental benefits and costs over 51M package (£b2011PV) Incremental benefits and costs compared with 51M proposal 51M incremental costs and benefits of HS2 Benefits 7.108 46-52 Costs to gov 1.173 25-23 BCR 6.06 1.6-2.3 Source: derived from Atkins (2012)
Lower speed options • HS2 Conventional line 9% cheaper • Atkins 2002 Conventional line 15% cheaper But loses 42% of the benefits • Civity 250-280 vs 300 km plus Capital cost 6.3% less Operating cost 2.8% less Benefits 15% less
Conclusions HSR only justified when volumes high (construction cost also crucial) Typically needs around 10m passengers per annum density on social cost benefit terms (much higher for commercial viability) Level of time savings also critical Should always compare with a range of options including: • Revised pricing ;policy to damp down demand • Upgrading existing lines • Building a new line for conventional speeds
