On an official tour in Toiryo, Mr. Sairam who was a chief development officer in Southern railway attended the seminar after taking a fast moving train. After the sernina4, he met his friend Orrtosaki. In a discussion, his friend told to Sairam, how Japanese people are focusing on energy conservation and saving of fossil fuels with the use of Maglev trains. To take idea about it, Sairam travelled from Tokyo to Osaka in Maglev train and observed that its sound is less as compared to Indian rails with smooth traveling.
