Singapore’s high population density and limited land resources require new innovative and energy and social sustainable transport solutions. With the announcement of LTA’s “Walk Cycle Ride SG” vision, Singapore is now on a green track. Providing green door-to-door commuter solutions, the island nation is moving towards a “car-lite” future. This transformation requires new first and last mile infrastructure resulting in a positive development of local communities, quality of life and public health.

A green transportation network requires green energy. Unfortunately, green energy is rare, often expensive and sometimes not available at all. Improving energy efficiency is therefore an important necessity. Based on results of international studies, the upcoming Speaker Series will address the challenges and possibilities of green transportation.

Energy efficiency and greenhouse gas emission at rail transportation
by Prof. Dr.- Ing Markus Hecht

Railways are the only powerful mode of transportation that can be operated Zero Emission immediately by using green electric energy (produced by Hydro, wind, sun or geothermal).But green energy is rare, expensive and sometimes not available at all. Therefore improving energy efficiency is important anyway and reduces operational costs. Compared to road and air transportation the priorities for railways differ in several points. The priorities for energy efficiency of railways are, according their importance:

  1. Adopt Capacity (avoid travel with partly loaded vessels)
  2. Electrification with brake energy recuperation
  3. Reduce running resistance
    3.1 Radial steering bogies for curvy tracks
    3.2 Aerodynamic optimisation for high speed
  4. Light weight construction
