Japan is all set to make heavy investments in building India?s high speed rail network programme. Under an Exchange of Notes signed between the two countries, India will get Japanese technology for the bullet trains as well as a total of $424 billion as loan for the programme. This includes funding for the Mumbai-Ahmedabad high speed rail corridor as well as the underground Phase III of the Mumbai Metro project. The 500km Mumbai-Ahmedabad corridor is expected to cost around 1 trillion yen. It will increase the speed of passenger trains on the existing Delhi-Mumbai route to 160-200kmph.
