Outline
•Motivation behind high speed rail investment
•Costs and benefits of high speed rail
•Examples of appraisals
•Conclusions
Origins and objectives of HSR (new lines 250km per hour or more)
1964 Tokaido Line
1981 Paris-Lyon
1981 Rome-Florence (1st section)
1988 Fulda-Wurzberg
1992 Madrid-Seville
2012 European total 6900km (Spain 2144; France 2036)
World 13000km (China 3426; Japan 2087)

Japan
•New Tokaido line opened 1964 (at 210kmph; later raised to 270)
•Previous line narrow gauge, slow and very congested
•By 2007 2176km of Shinkansen built; 4000km more in basic plan
•27% of passenger km rail (dominates on trips of 300-800km)
•Lines built by a government agency (Japan Railway Construction, Transport and Technology Agency); leased to private operators on a charge based on ability to pay
Japan – why rail so successful?
•127m people mainly in large cites along the coastal strip
•Very high population densities
•Car transport expensive (toll motorways)
•New Tokaido line now carries well over 100m passengers p.a.; fully profitable
• Later lines serving much lower population and require high subsidies

Costs and Benefits
COSTS
•Capital costs
•Net Operating costs
•Net External costs (environment, safety)
BENEFITS
•Time savings and improved reliability
•Additional capacity
•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
HS1 – 70 per km
HS2 - 95 per km
Operating costs depend mainly on rolling stock requirements, staff, energy, wear and tear – note very high utilisation of assets may offset high energy costs

Value of time - issues
•Should we have different values of leisure time by mode?
•How should time spent waiting and interchanging at airports be valued ?
•Is the business value of time lower if time spent travelling can be usefully employed?
•What if journeys start and finish out of normal working hours?
•Do savings in labour cost lead to equivalent increases in GDP?
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 benefitsfrom generated traffic
•Causes?
-labour supply
-agglomeration externalities
- Imperfect competition
Within HS2, no labour supply impact assumed
Agglomeration benefits solely from commuter journeys up to 75km on conventional rail and road
Longer journeys have little impact because of distance decay and small rail market share (but isn’t rail important for precisely those journeys most likely to produce WEBs?)

Conclusions
Case for HSR depends on:
-Construction cost
-Value of time savings
-Demand
Typically requires 10-12m passengers per annum
Maybe less if there are strong network benefits
Maybe more in a country with low values of time.
