How much does TGV cost to build?

TGV Construction Costs: A Historical Perspective

The construction costs of the French high-speed rail network, known as the TGV, have undergone significant variation over the years. Early projects, such as the TGV Sud-Est, were remarkably economical at approximately $4 million per kilometer.

However, subsequent lines and the latest TGV Méditerranée have pushed costs up to around $15 million per kilometer. This reflects the evolving nature of technology and infrastructure, as well as the increased complexity of subsequent projects.

The TGV Sud-Est, which opened in 1981, was built at a time when high-speed rail technology was still in its early stages. The line was relatively straightforward to construct, as it followed a mostly flat and open terrain. The low construction costs of the TGV Sud-Est were also due to the use of innovative construction methods, such as prefabricated track sections.

In contrast, subsequent TGV lines have been more expensive to build. The TGV Méditerranée, which opened in 2001, cost approximately $15 million per kilometer. This higher cost was due to several factors, including the line’s more complex route, which required the construction of tunnels and bridges. The line also features more advanced technology, such as onboard computer systems and signaling systems.

Despite the higher costs, the TGV has proven to be a successful investment. The network has carried over 3 billion passengers since its inception, and it has helped to reduce travel times between major cities in France. The TGV has also played a key role in the development of high-speed rail technology around the world.
