Pay attention to the news window glass What is the performance of JR Tokai's new train "315 series"?

Points that are worrisome in "building a house"

The new 315 series train arrived at Nagoya Station, where the press is waiting (February 1, 2022, photographed by Echinori Echinori).

　JR Tokai held a test drive for news on February 1, 2022 (Tuesday) for the news of the new vehicle "315 Series". The smell of a new car is on the test drive train, which ticks the nasal cavity, and has made a round trip between Nagoya and Tajimi. [Photo] The 315 series was a window of "Pulling in front", and this 315 series is a train assuming use in everyday scenes such as regular trains. Roughly speaking, it has evolved that it is safer, comfortable, and has high security and security, but there is one point that I want to actually ride and pay attention. It is a "window". In recent years, when searching for a house or building a new building, the performance of the window glass is one of the points to be worried about. "Double glass" with a hollow layer in between two or more glasses, which enhances indoor comfort with high heat insulation and sound insulation, has appeared in various ways. It is not unusual for vehicles for ordinary trains to use multi -layered glass on the window of the door (it is said to prevent the door window glass from dewing and standing). Meanwhile, the 315 series of JR Tokai, which appeared this time, also uses multi -layered glass for room windows other than doors. It was a multi -layer glass with a performance of infrared and UV rays 99 % cut, and even if I put my hand from the room from the room side over the window that had been in direct sunlight, I did not feel any special heat. The adoption of this highly insulated multi -layered glass has the effect of saving energy in summer air conditioning, making it difficult to condensation in winter, and is also effective in reducing the noise in the car. This double glass of the 315 series can be said to be one of the performance and evolution (there is no other car for regular train).

Some people were acclaimed

　In addition, the 315 series adopts a mechanism that operates the lever and defeats inside the room window. It seems that the method of opening the window vertically is because it is heavy to lower it with multi -layered glass. In addition to the 315 series, the main features are as follows.・ Improve ride comfort (the same bogie structure as the new limited express vehicle HC85 series).・ Reduced noise in the car by introducing low noise floor structures and multi -layered glasses.・ Improved the ability for cooling and introduced fine control by AI for the first time in Japan.・ The shape of the seat is reduced to the waist, and the width is increased by 1cm.・ In addition, adding leather and handrails. The string leather is three steps in height, making it easier to use.・ The guide device for the full -color LCD display is installed in the car.・ One wheelchair space is installed on all vehicles.・ The steps between the platform and the vehicle are reduced. Easy to get on and off with strollers.・ Enhanced in -car security, such as installing 5 places in the car in the car per car.・ Equipped with an emergency battery that can be driven even during a power outage.・ Energy saving is realized (power consumption is reduced by 35 % compared to the 211 series). By the way, at this test drive, there was a reporter who praised the seats with a structure that supported the waist, saying, "This is good for back pain!" JR Tokai's new vehicle "315 series" will start running between Nagoya and Nakatsu River on the Chuo Main Line from March 5, 2022 (Saturday).
