The scale of investments in high-speed rail (HSR) raises questions about the most appropriate methods of appraisal. Increasingly the reliance on conventional cost–benefit analysis, based essentially on the direct benefits to users and the direct costs to operators, has been questioned.
In India, the project to build the country’s first 500-kilometer high-speed railway (HSR) from Mumbai to Ahmedabad is underway. For comparison, all top 10 economies in the world except the United States have constructed several HSR lines in the past 30 years. The People’s Republic of China (PRC) alone has built nearly 28,000 kilometers of HSR in the past 20 years. Nevertheless, opinion makers in India are expressing contradicting views, questioning whether it is suitable for the country to develop expensive infrastructure such as HSR.
As we are increasingly relying on technical innovations to solve some of society’s most complex problems, technological advancements such as artificial intelligence are contributing to new, modern modes of transportation, especially to enhancing safety. However, technology is only one of many critical factors for safety, and there is a need to understand the other factors.
Since its inception in Japan in 1964, high-speed rail (HSR), and its impact on the economy, has received attention from policymakers worldwide. Early HSR development was more of a race to go faster, and the early success led policymakers around the world to believe in the power of HSR for catalyzing growth.

In 1969, Professor Edward Norton Lorenz coined the term “butterfly effect” to state that subtle changes in conditions can influence or cause seemingly unrelated results elsewhere. The flutter of a butterfly’s wings at place A can eventually develop into a hurricane at place B even though A and B are not related. Almost two decades after the term was coined, Japan National Railways (JNR) was privatized and split into several corporations, and now JR East manages the largest network of railway lines in Japan.
