High-Speed Rail: A Start in Japan |
Global spread
High-speed rail projects have been progressing worldwide
in recent years. A high-speed rail network is being planned
and built in Europe to link major cities and enhance the
transport network within the European Union (EU). In Asia,
with its high population density, high-speed railways are
being constructed and plans formulated to stimulate further
economic growth by linking large cities and improving
transport infrastructure. China in particular is proceeding with a monumental construction plan spanning a total of
about 20,000 km (including commercial operation at less
than 250 km/h). In addition, even emerging economies are
going forward with high-speed rail plans in the Middle East,
South America, and Africa (Figure 1).
There are many factors behind this global spread of
high-speed rail, including moves to switch from automobiles
to railways due to increased awareness of the global
environment, construction of major transport infrastructure
for economic growth, and expectations for jobs creation and
economic ripple effects. |

Pioneering Tokaido Shinkansen |
Looking back at the history of high-speed rail, the Tokaido
Shinkansen started operation as the world’s first high-speed
railway along the 515-km route between Tokyo and Shin-
Osaka on 1 October 1964, just ahead of the Tokyo Olympics.
It achieved revolutionary success and contributed greatly to
Japan’s high economic growth. At a time when railways were
in decline due to the rise of personal automobiles, faster rail speeds between cities proved an effective stimulus in the
resurgence of railways worldwide.
After studying the Tokaido Shinkansen technology in
detail, France’s TGV started operation in 1981 at what was
then the world’s fastest speed of 260 km/h. Today, Japan’s
shinkansen and France’s TGV are the world’s top highspeed
rail systems, and the Tokaido Shinkansen can be
said to be the pioneer in high-speed rail because it was the
first to secure success. |

High-speed rail networks spanning 20,000 km |
Subsequently, high-speed trains started running in the
Western European nations of Italy (exemplified by ETR),
Germany (ICE), Spain (AVE), Belgium (Thalys), the UK
(Eurostar), and the Netherlands (Thalys). Following Europe,
high-speed railways were also built in the East Asian
countries of South Korea (KTX), Taiwan (Series 700T), and
China (CRH). High-speed trains also started to operate in
Turkey (YHT) and Russia (Sapsan) (Table 1).
There is now a total of 20,423 km of specially built highspeed
lines (maximum commercial operating speed of
250 km/h or faster) worldwide (at late December 2013).
Moreover, the maximum commercial operating speed of
high-speed trains running on these lines is 300 to 320 km/h
in most countries with high-speed railways. |
Defining High-Speed Rail |
High-speed rail is often not defined clearly when discussed,
so an explanation is provided here first. Article 2 of Japan’s
National Shinkansen Railway Development Act (1970)
defines a ‘shinkansen railway’ as an ‘artery railway that is
capable of operating at the speed of 200 km/h or more in its
predominating section’. This might be used as the definition
of high-speed rail, but most conventional lines in Europe are
standard gauge (1435 mm) with fewer curved and graded sections than in Japan, so the UK, France and Germany
have many lines capable of operations at around 200 km/h
even without constructing specially built lines. Thus, defining
high-speed rail as having speeds of 200 km/h or more would
make organizing statistical data on the total length of highspeed
rail very difficult when comparing individual countries.
The International Union of Railways (UIC) tabulates
specially built high-speed lines equipped for operation at
250 km/h or faster as high-speed rail. With advances in
technological development of higher speeds, high-speed
operation in the 300 km/h or faster range is becoming the
norm globally. Therefore, it is not practical to define highspeed
rail as having speeds of 200 km/h or more.
Defining high-speed rail as having a maximum
commercial operating speed of 250 km/h or more
eliminates high-speed conventional lines of around 200
km/h and limits the definition to dedicated specially built
high-speed lines on which high-speed trains run. This
definition is used in this article.
It is worth noting that a conventional line between
Moscow and St Petersburg in Russia was upgraded to
run Sapsan (Peregrine Falcon) high-speed trains with a
maximum commercial operating speed of 250 km/h. While
this is a conventional line, not a specially built high-speed
line, here it is treated as a high-speed rail line. |

Trends and Data Comparisons |
History of construction of specially built high-speed lines
Japan held the title of having the greatest length of highspeed
rail lines in the world for a long time after the
opening of the Tokaido Shinkansen in 1964. However,
China took the lead in 2009 as it rapidly built a high-speed
rail network connecting major cities from the beginning of
the 21st Century. At late December 2013, China had 9904
km of specially built high-speed lines (48% of global total
of 20,423 km), making it a high-speed rail giant in a short
time span (Figure 2). In Europe, France, Germany, Spain, and Italy are
gradually expanding the length of their high-speed lines
in accordance with the high-speed rail plan for Europe
as a whole. Recent growth by current third-place Spain (2225 km, 11% of global total) has been dramatic, closing
in on second-place Japan (2388 km, 11%).
Construction and planning of high-speed rail in
emerging economies is progressing, but only Saudi Arabia
and India come even close to developed high-speed rail
countries in terms of track length. Their future developments
will be watched closely.

Maximum Commercial Operating Speed |
The current maximum commercial operating speed is
320 km/h in France (TGV), Germany (ICE3), and Japan
(Hayabusa and Komachi). The Chinese high-speed railway
that opened between Beijing and Tianjin (115 km) in August
2008 in conjunction with the Beijing Olympics initially
started at the world’s fastest commercial operating speed of
350 km/h, and the high-speed railway between Wuhan and Guangzhou (968 km) that opened in December 2009 also
started at 350 km/h. However, the 23 July 2011 collision and
derailment at Wenzhou, Zhejiang Province, caused speeds
to be lowered to about 310 km/h.
As an aside, the speed record for iron wheel on rail
high-speed trains is 574.8 km/h set by France’s TGV on
3 April 2007 before the opening of the LGV Est Line. The italo high-speed train developed by Alstom based on the
test train that set this world speed record was dubbed the
ETR 575. |
Maximum average speeds between stops |
Every 2 years, Railway Gazette International announces the
ranking of average speeds between stops for high-speed railways in commercial operation in individual countries.
Figure 3 shows a table summarizing data from 2001 to now.
These figures are calculated from Thomas Cook’s European
Rail Timetable and Overseas Rail Timetable.
In the latest ranking from 2013, China’s prominence
really stands out with a maximum average speed of
316.6 km/h on the Shaoguan–Leiyang Xi section of the
specially built high-speed line between Wuhan and
Guangzhou. This record is followed by France’s LGV Est
Line between Larraine TGV and Champagne-Ardenne TGV
at 271.8 km/h, Spain’s Madrid–Barcelona high-speed line
between Guadalajara-Yebes and Calatayud at 269.0 km/h,
Japan’s Tohoku Shinkansen between Omiya and Sendai
at 263.4 km/h, Taiwan between Zuoying and Tahichung at
256.4 km/h, Italy between Milano Rogoredo and Bologna
Centrale at 232.2 km/h, Germany’s Köln–Frankfurt highspeed
line between Frankfurt Flughafen and Siegburg/
Bonn at 226.3 km, Korea’s Gyeongbu High Speed Railway
between Gwangmyeong and Daejeon at 212.0 km/h, and
Turkey’s line between Eskisehir and Polatli at 203.5 km/h. |

Gauge and interoperability |
Most countries with high-speed railways have adopted standard gauge (1435 mm) for specially built high-speed lines. In other words, while Japan and Taiwan use narrow gauge (1067 mm) for conventional lines and Spain uses broad gauge (1688 mm), the gauge of specially built highspeed lines is 1435 mm. However, the conventional line (1520 mm) between Moscow and St Petersburg in Russia was upgraded to operate Sapsan high-speed trains at a maximum commercial speed of 250 km/h.
The gauge of conventional lines in Europe, South Korea, and China is also 1435 mm, so high-speed trains running on specially built high-speed lines can run throughservices directly onto conventional lines. Consequently,in those countries, the ripple effect of speed increases is much greater than in Japan where conventional lines (1067 mm) and shinkansen lines are different gauges.
In Europe, international high-speed trains such as Eurostar and Thalys were developed to run on different electrical and signalling systems to enable interoperability between EU countries.The TGV and ICE also operate across borders. |

Distributed Traction and
Concentrated Traction Systems |
There are two types of high-speed trains: the
EMU type (distributed traction system) such as
Japan’s shinkansen, where motors are installed in
passenger cars, and the type where locomotives
are placed at each end (concentrated traction
system) such as France’s TGV. Japan has always
used the distributed traction system since the
original Tokaido Shinkansen. Since the inception
of the French TGV in 1981, the concentrated
traction system has been the main type used
in Europe such as on Germany’s ICE1, Spain’s
AVE S100, the international high-speed Eurostar,
Italy’s ETR500, and Thalys (Figure 4). The distributed traction system has many
advantages in terms of energy efficiency and
efficient transport. Major examples are light axle
weight, high acceleration and deceleration, more
cabin space as there are no locomotives, and
ability to utilize the energy of regenerative braking efficiently. Moreover, compact and
light AC motors have been used
instead of conventional DC motors
since the Series 300 shinkansen,
reducing motor maintenance. These
advantages prompted European and
Asian railways to adopt the distributed
traction system as the main type,
starting with the German ICE3 that
debuted in 2000.

Figure 6: Shinkansen Transport Density (fiscal 2011) |
Transport Density |
Transport volume differs with factors such as population,
economic strength, and industrial structure of cities along highspeed
railways. Transport density is an index often used to
compare transport volume of different lines. Transport density
(passengers per day) calculated as annual passenger-km
÷ 365 days ÷ kilometers of commercial lines expresses
the average transport volume (number of passengers)
per km per day, and it is unaffected by the line length.
Figure 5 shows the 2011 transport density of high-speed
railways in major countries based on UIC data. This figure shows Asian high-speed railways running in regions of dense
population (Japan, Taiwan, South Korea) rank at the top. It
is necessary to be careful when looking at Figure 5 to note
that UIC data is assumed to include the transport volume of
high-speed trains where those trains travel on conventional
lines (maximum commercial speed in excess of 160 km/h),
so the transport density on just specially built high-speed
lines in South Korea and Europe may be greater than shown.
Transport density on European specially built high-speed
lines is about 20,000 to 30,000 people per day, and to give
railways a competitive advantage over other transport modes,
it is necessary to exempt railway companies from bearing
infrastructure costs. So policies to separate infrastructure
and operations are inevitably adopted. Unfortunately, the
UIC data does not include China’s high-speed railways, so
comparisons cannot be made, but it would be interesting to
know how many people use high-speed rail in China.
Comparing the transport densities of Japan’s shinkansen,
Figure 6 shows the Tokaido Shinkansen is overwhelmingly
large at 220,000 passengers per day (fiscal 2011 here and
hereafter), giving it the greatest high-speed rail transport
density in the world. That is followed by the San’yo
Shinkansen at 74,000 passengers per day, the TohokuShinkansen at 51,000, and the Joetsu Shinkansen at 40,000.
The Hokuriku (Nagano) Shinkansen and Kyushu Shinkansen,
built as a part of projected shinkansen lines, based on the
Nationwide Shinkansen Railway Development Act, have
transport densities of 18,000 and 17,000 passengers per
day, respectively.
The transport densities of these high-speed railways
differ greatly by line, so the number of cars per train set,
number of train runs, and wayside equipment are designed
based on transport demand. Moreover, since transport
volume affects profitability, business schemes and funding
for constructing high-speed railways differ by line. |

Technology transfer from pioneers to other countries |
Currently, the only countries with high-speed railways that
developed their own systems from the start are Japan, France,
Germany, and Italy. All other countries introduced systems
from these high-speed rail pioneers to build their highspeed
railways. Roughly, Spain based its high-speed rail on
technology from France and Germany; Belgium, the UK, the
Netherlands, and South Korea on that from France; Taiwan
on that from Japan; China on that from Japan, France, and
Germany; and Russia on that from Germany. In recent years, Spain, South Korea, and China too
have expressed the intention to participate in overseas
high-speed rail projects through transfer of high-speed
rail technologies. For example, the Spanish rolling stock
manufacturer CAF is delivering YHT (Yüksek Hizli Tren,
meaning high-speed train in Turkish) high-speed rolling
stock for Turkey’s high-speed railway.
|
Competitive distance range |
Conventionally, the range at which high-speed rail has
the advantage over air and automobiles has been said to
be within a travel time of 3 hours and distance of 300 to
500 km (this range may differ depending on set fares and
operation frequency). However, it has expanded recently to
about 4 hours or 300 to 800 km due to increased time for
security checks at airports relating to the threat of terrorism,
traffic congestion on the way to the airport in some cities,
increased amenities on high-speed trains, and speed
increases to over 300 km/h. For reference purposes, the Eurostar connecting London
and Paris (492 km) carries more than 80% of the passengers
travelling between those cities. In Spain, the completion
of a specially built high-speed line between Madrid and
Barcelona (621 km) in February 2008 caused a sharp
increase in the share for railways from 12% to 41%.

Construction and Planning in Countries
without High-Speed Rail |
As stated at the start of this article, high-speed railways are
being constructed, planned or investigated, and bidded
around the world for reasons such as to create economic
growth corridors and improve environmental issues and
energy efficiency. While the level of maturity of these new
projects ranges from the idea stage to the implementation
stage, high-speed rail construction and planning is
ongoing worldwide, including Asia (Vietnam, Thailand,
Malaysia, Singapore, Indonesia, India, Kazakhstan), the
Middle East (Saudi Arabia, Qatar, Iran), Europe (Russia,
Sweden, Norway, Denmark), Africa (Morocco, Egypt, South
Africa), the Americas (Canada, USA, Brazil, Argentina), and
Oceania (Australia).
In countries that do not have high-speed rail yet,
construction has already started in Saudi Arabia on the
Haramain High-Speed Rail linking Mecca and Medina
for transporting pilgrims, and in Morocco. Construction
in Morocco is based on introducing the TGV system, and
all-bi-level TGV Euroduplex cars will be operated when it
opens in 2015. Spain’s Talgo and ‘big three’ member
Bombardier received orders for Saudi Arabia’s high-speed
rail system and construction is currently underway. |
Future Outlook |
Era of top operating speeds above 350 km/h
The current top commercial operating speed is 320 km/h,
but a speed of 350 km/h has been achieved in China
(albeit temporarily). In Italy, the ETR1000 high-speed
train is scheduled to be introduced in 2015 with a top
commercial operating speed of 360 km/h. In other words,
the top commercial operating speed of high-speed rail will
soon exceed 350 km/h. Since the distance at which highspeed
rail has an advantage over air travel is determined
by travel time, increasing the scheduled speed to about
300 km/h gives high-speed rail the advantage at distances
up to about 1000 km. However, further speed increases
are not necessary to maintain the advantage when there is
no competition with other forms of high-speed transport,
especially air travel.
|
Level of maturity and feasibility of high-speed rail projects |
Planning and construction of high-speed railways is
spreading from the traditional markets of Western Europe
and East Asia to other countries as well. Making high-speed
rail a reality requires securing profitability of projected lines,
national economic power, political will, and international
events such as an Olympics as a completion target.
Looking at the 10 high-speed rail project corridors
currently planned in the USA, nearly identical routes
were considered and surveyed as far back as the 1980s.
People who thought high-speed rail could be achieved in
Taiwan were a minority when the implementation plan was
formulated more than 20 years ago, but it opened in 2007.
Moreover, there was excitement around 1990 when it was
suggested that Australia would soon be starting construction
on a high-speed rail project, but that project is still in the
planning stage. In other words, while many high-speed rail
projects are being planned currently, it is important to realize
that some will be achieved while others will not. |
Challenges in achieving high-speed rail |
It goes without saying that railways are an industry closely
related to the characteristics of the countries and regions
where they are deployed, reflecting the natural and social
environment, so a high-speed rail system that fits the
country or region must be adopted. Transport density has
already been mentioned above, but the expected transport
density of high-speed railways being planned worldwide
today is only equivalent to that of projected shinkansen lines
in Japan. Taking these factors into account, high-speed
rail must be planned considering the transport situation in
the countries where it is to be introduced. Freight transport
was also considered for the Tokaido Shinkansen when it
was originally planned, so high-speed rail projects where profitability is achieved by including freight transport are a
possibility. Many recent high-speed railways have been planned
as public-private partnerships (PPP) projects. Under
such schemes, private-sector financing and technology
are supplemented by public funds and governmental
cooperation to develop high-speed railways. With PPP, many
challenges have to be considered at planning, including
how to bear demand risk, methods for procuring funds
from the public and private sides, establishment of specialpurpose
companies (SPC), construction and rolling stock
procurement, operation and maintenance.
Moreover, projects in developing countries often involve
greater risk than in countries with advanced high-speed
railways. For example, an Iranian high-speed railway
modelled on the Japanese shinkansen was being planned
to link the capital of Tehran with the holy city of Mashhad
during the reign of Shah Pahlavi, but that vanished with the
1979 Iranian revolution. In Korea, the Gyeongbu High Speed
Railway linking the capital Seoul with Busan was in danger
of not coming to fruition due to the 1997 currency crisis,
but then-president Kim Dae-jung made the decision to split
construction into two phases, saving the project from failure.
In any case, there are many challenges that must be
considered and dealt with from planning to achievement
of high-speed rail projects. The era of constructing and
opening specially built high-speed lines where transport
demand is high is already coming to an end, and future
high-speed railways must come up with business schemes
and methods for procuring funds where there is lower
transport demand. Strong leadership by politicians in those
countries as well as financial soundness are imperative for
bringing such projects to fruition.
