Due to extreme heat conditions in Ahmedabad, Japan is making some changes in Bullet train

The bullet train seen in this photograph is the E5 Model. This train will operate in India. The officials from Japan involved in the bullet train informed me that all the photographs published of the bullet train in India are of the Chinese bullet train. After saying that, they gave me this picture.
We have reached Chiyoda-ku, the very famous area of Tokyo. The fast pace of life here shows that the people involved in building the fastest train of the world must be working here. Here is the famous building known as Kasumigasuki! In this building sits the top-most official who is extremely busy working on the proposed Mumbai-Ahmedabad Bullet Train. As soon as I reached the office, I was introduced to the top-most official of the Ministry of Land, Infrastructure, Land and Tourism of Japan (MLIT). As soon as he greeted me in the Japanese tradition, I asked him how far has the work of our (India) bullet train reached? The reply was provided by Mr. Tomoyuki Nakano, Director, International Engineering Affairs Railway Bureau, MLIT. Mr. Nakano informed that in India they will operate the E5 model of bullet train. The designing of the train is in its final stages. But, however, considering the climate of the India, we have to make a few changes in the E5 model that is being used in Japan. In Japan, the maximum temperature in summer reaches between 30-35ºC, while in India, we have to operate the bullet train the range of 45-47ºC, so we have worked differently on AC technology so that even in high temperatures, there is no risk of the bullet train catching fire. During the discussion, Mr. Nakano stressed that the engine of the train is also different. We have improved upon the propulsion efficiency, so that even in hot temperatures, the train can safely run at a speed of 320 km per hour. The MLIT officials informed that they have divided the Mumbai-Ahmedabad bullet train project in four phases. The first phase includes the detailed designing of the entire project; the second phase will be the process of issuing tenders by end-December 2018; third phase involves the procurement of rolling stock and construction work while the fourth and the final phase would be the commercial operation of the bullet train. In response to our question as to when would the bullet train start in India, Mr. Nakano replied that their initial plan was to start it in 2023, but the Modi Government wants to start it in 2022 as it coincides with India completing 75 years of independence.
