China's High Speed Rail Plans at Home & Abroad

Since serious Chinese planning of high-speed rail (HSR) networks began in the 1990s under the guidance of the Ministry of Railways (MoR), rail planners have sought to create independently trademarkable Chinese brands capable of competing in global markets in addition to confronting domestic transport inefficiencies and improving air pollution. This success of this effort to absorb foreign technology has implications for world railway markets, but also serves a case study of China’s approach to technology acquisition.

Previous Chinese participation in the world HSR market was limited due to the inferiority of its technology relative to established Western and Japanese manufacturers despite lower labor and resource costs and favorable government financing. However, China appears to have pursued a “technology for market access” strategy to enhance the global competitiveness of domestic HSR companies. These policies and the modus operandi of the Chinese government are explicitly stated in official documents and state media which detail the use of technology transfer agreements as a key component in realizing technology development goals.

Poorly formulated technology transfer agreements may constitute more of a threat to the competitiveness of Western enterprises (particularly ones reliant on high-technology which consume significant amounts of capital and resources in research and development) than that from Chinese cyber economic espionage. The latter is primarily associated with obtaining knowledge such as patents and technical schematics, whereas the former often involves training the receiving party in how to skillfully exploit the knowledge. This not only potentially accelerates rival product development but also reduces financial and time costs of process optimization.

Chinese train-makers and civil engineering companies are now building, participating in or contemplating bidding for HSR construction projects in South America, the US, Saudi Arabia and Russia.

Trains May Be Worse for Global Warming Than Planes

True or false: taking the commuter train across Boston results in lower greenhouse gas emissions than travelling the same distance in a jumbo jet. Perhaps surprisingly, the answer is false.

A new study compares the "full life-cycle" emissions generated by 11 different modes of transportation in the US. Unlike previous studies on transport emissions, this one looks beyond what is emitted by different types of car, train, bus or plane while their engines are running and includes emissions from building and maintaining the vehicles and their infrastructure, as well as generating the fuel to run them.

Including these additional sources of pollution more than doubles the greenhouse gas emissions of train travel. The emissions generated by car travel increase by nearly one third when manufacturing and infrastructure are taken into account. In comparison to cars on roads and trains on tracks, air travel requires little infrastructure. As a result, full life-cycle emissions are between 10 and 20 per cent higher than "tailpipe" emissions.

Mikhail Chester and Arpad Horvath of the University of California, Berkeley, included in their calculations data on the "life expectancy" of each component of each mode of transportation, such as the tracks used by a train and the airports used by aircraft.

They calculated the total "travel kilometres" each component allows and how many tonnes of greenhouse gases were emitted to build and maintain each component. This allowed them to calculate the component's emissions per kilometre travelled, for each mode of transport per kilometre for each traveller on board.


oh my...
