Is mrt sustainable?

http://www.uncrd.or.jp/env/4th-regional-est-forum/Presentations/18_BS5_Singapore.pdf All SMRT trains run on electricity and generate zero air polluting emissions. Regenerative braking technology converts kinetic energy to electricity, which powers other trains and stations. Travelling on our train network is more energy efficient and lowers your carbon footprint to 13.2g per passenger-kilometre. Singapore’s MRT network was built after a ten-year debate between consulting teams representing the pro-MRT and the pro-bus ideas, with a main focus on the cost-benefit associated with the proposed MRT (Richmond 2008). A decision was made by the government to launch the rail based MRT in 1982. This system was consequently built and put in operation in 1987. At the present, it has three lines in operation and the fourth line in construction The public transport network and the road system are designed in an integrated way with land use through careful coordination in physical planning, with macro level coordination between Mass Rapid Transit (MRT) lines and new towns, and micro level integration around MRT stations . physical networks of public transit are integrated using a hub-and-spoke structure. The hubs or town centres are linked by the MRT, while Light Rapid Transit (LRT) and buses connect the housing estates to the MRT stations.
