According to the UIC and IEA, the transportation sector is responsible for almost 23% of CO2 emissions worldwide [1]. That problem is does not only apply in environmental issues, but it also affects transportation costs.

​

Transportation companies trying to reduce energy costs, in order to be financially efficient. Some of the measurements addressed below, have been applied in practice in European railway companies. GYM platform and similar solutions belongs to this set of measurements.

​

The first solution comes from rolling stock manufacturers. Bombardier believes that a good aerodynamic shape can reduce energy consumption up to 15%. According to SIEMENS and ALSTOM, a new type of electric engine could increase energy efficiency by 3% and a new diesel engine, up to 40% [2]. Railway operators like Russian Railways experiments on LNG-powered locomotives with up to 80% reduction in GHG emissions [3]. Evidently, heavy masses belong to the past. ALSTOM uses new materials like Silicon Carbide with 45% less mass which leads to 4% less energy consumption [4]. For implementation of energy reduction measurements, many companies promote smart meters for electricity and diesel consumption [5].

​

Furthermore, the second phase of the solution, comes from energy reduction techniques. Energy recovery from braking technique has already been tested in Spain [6]. This comes together with eco – driving and driver advisory systems. One of these systems has already been implemented in Hellenic region from local railway operator TRAINOSE [7], reducing energy consumption up to 20%.

​

Journey Planners put all the described solutions in a box and proposed a different way for energy reduction. Such platforms put trains and busses side by side, promoting the most efficient solution. Up to now passengers, did not have the opportunity to choose the most environmental way of travelling automatically in one – packet solution. These platforms offer new synergies in co-modality promoting a new revolution in transportation.
