Indian Railways: The Economics of a Giant
The Bullet Train: Worth the Cost?
The economics of the Mumbai-Ahmedabad high-speed rail project, how it is financed with a Japanese loan, and the debate over its costs and benefits.
India’s first high-speed rail line connects Mumbai and Ahmedabad, about 508 kilometres.
The project
- Uses Japan’s Shinkansen technology.
- Planned top speed around 320 km/h.
- Estimated cost around 1.08 lakh crore rupees originally, with later revisions upward.
Financing
About 80 percent is funded by a Japanese loan at a very low interest rate (around 0.1 percent) with a long repayment period of 50 years.
Delays
Land acquisition, especially in Maharashtra, delayed the project. The first section in Gujarat was expected to start later in the decade.
Arguments for
- Faster travel between two major economic centres.
- Technology transfer and skills.
- Regional development around stations.
Arguments against
- High cost per kilometre.
- Opportunity cost: the same money could upgrade many ordinary routes.
- Ridership: fares must be affordable to fill trains; air travel competes.
The economist’s approach
A cost-benefit analysis compares total costs to benefits like time saved, fewer accidents and less pollution, over decades.
A business traveller who today takes 6 to 7 hours by regular train could make the trip in about 2 to 3 hours, saving a full working day on a round trip.
The loan must be repaid, and the money could be used elsewhere.
- The Mumbai-Ahmedabad high-speed line is about 508 km.
- About 80 percent is funded by a cheap Japanese loan.
- Land acquisition delayed the project.
- Cost-benefit analysis weighs time saved against opportunity costs.
