Prime Minister Narendra Modi and his Japanese counterpart Shinzo Abe launched India's first bullet train project in Ahmedabad today. The joint venture between Indian Railways and the Japanese firm Shinkansen Technology is expected to cost Rs 1.10 lakh crore for the first link - a 508-km stretch between Ahmedabad and Mumbai. The new train - which will be able to carry 750 passengers -- will make 70 sorties a day. Its top speed will be around 320 km per hour -- more than double that of the fastest train in India. The average speed will be 250 km per hour.
