examining models in which values of key parameters are varied to see in what
circumstances benefits exceed costs, and secondly looking at the limited evidence from ex
post studies, mainly for France and Spain. We then turn to British experience of the
appraisal of HS2 – the proposed line linking London to Birmingham, Manchester and Leeds. It
is concluded that the main factors determining economic success for high speed rail projects
are construction costs, value of time saving per passenger and traffic volume and degree of
congestion of existing transport networks. The biggest uncertainty regarding the case for
high speed rail surrounds the possibility of wider economic benefits.

Abstract: This paper presents a long-term investment planning model that co-optimizes
infrastructure investments and operations across transportation and electric infrastructure
systems for meeting the energy and transportation needs in the United States. The
developed passenger transportation model is integrated within the modeling framework of a
National Long-term Energy and Transportation Planning (NETPLAN) software, and the model
is applied to investigate the impact of high-speed rail (HSR) investments on interstate
passenger transportation portfolio, fuel and electricity consumption, and 40-year cost and
carbon dioxide (CO2) emissions. The results show that there are feasible scenarios under
which significant HSR penetration can be achieved, leading to reasonable decrease in
national long-term CO2 emissions and costs. At higher HSR penetration of approximately 30%
relative to no HSR in the portfolio promises a 40-year cost savings of up to $0.63 T, gasoline
and jet fuel consumption reduction of up to 34% for interstate passenger trips, CO2
emissions reduction by about 0.8 billion short tons, and increased resilience against
petroleum price shocks. Additionally, sensitivity studies with respect to light-duty vehicle
mode share reveal that in order to realize such long-term cost and emission benefits, a
change in the passenger mode choice is essential to ensure higher ridership for HSR.

Abstract: This paper explores OUIGO (pronounced ‘we go’), the low-cost high-speed rail
(HSR) service launched by the French state-owned railways in April 2013. In this exploration,
we (1) compare OUIGO with the traditional French HSR and the low-cost airlines (LCAs), and
(2) analyse fares proposed by OUIGO and its competitors. We thus analyse the new service in
terms of production conditions, communication, marketing, booking, network geography,
at-terminal and on-board experience and fares. We find that the railway industry’s
constraints (including market regulations, technical rigidities and incumbent employment
