In the next 20 to 30 years, the long-term economic growth, demographic changes and the need to reduce energy consumption will impose an increasing transport capacity by building high-speed lines. Also, according to estimates in the area, railway high-speed transport brings significant improvements to economic competitiveness, and helps optimise the investment segment of the regions they cross.
Even though most European countries don’t have high-speed lines, the attention of the authorities in these countries is more and more drawn by projects for the development of high-speed transport systems. The development of high-speed lines in Europe has been encouraged and financially supported by the EC. Currently, this sets the foundation for the implementation of more and more high-speed line construction projects.
Compared to conventional transport, high-speed transport services significantly reduce travel time, help improve travelling conditions, optimise passengers’ comfort and are more attractive leading to an increased number of passengers, both nationally and on international routes.
Currently, the authorities’ attention is captured by this modern type of transport as they realise that the implementation of these projects will permit improve transport connections, create more attractive conditions for passengers, increase comfort and safety. Thus, the decision makers become aware of the fact that these more attractive conditions mean encouraging a higher number of passengers to use this means of transport.
Another advantage of high-speed transport compared to traditional railway transport is energy consumption, a very important element in evaluating different types of trains. The key measures at hand for reducing the energy consumption of electric trains include reducing weight, improving aerodynamics (extremely important for high-speed trains) and optimising energy efficiency, including recuperative braking systems.
According to a study conducted by Network Rail, experts believe that the relative performance of high-speed and conventional transport is not expected to significantly change the future.
The information obtained on the energy consumption of Alstom’s AGV trains and Hitachi Super Express has been considered benchmark for conventional and high-speed rolling stock for 2025-2030. These trains have an increased capacity (650-649 passengers) and similar length (250m, 260m respectively). The relative impact of energy consumption will significantly drop in the future, once the power generation process is de-carbonised.
