Shinkansen - Wikipedia 7/3/20, 1048 AM
Shinkansen - Wikipedia 7/3/20, 10)48 AM Shinkansen The Shinkansen (Japanese: 新幹線, pronounced [ɕiŋkaꜜɰ̃ seɴ], lit. ''new trunk line''), colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. Initially, it was built to connect distant Japanese regions with Tokyo, the capital, in order to aid economic growth and development. Beyond long-distance travel, some sections around the largest metropolitan areas are used as a commuter rail network.[1][2] It is operated by five Japan Railways Group companies. A lineup of JR East Shinkansen trains in October Over the Shinkansen's 50-plus year history, carrying 2012 over 10 billion passengers, there has been not a single passenger fatality or injury due to train accidents.[3] Starting with the Tōkaidō Shinkansen (515.4 km, 320.3 mi) in 1964,[4] the network has expanded to currently consist of 2,764.6 km (1,717.8 mi) of lines with maximum speeds of 240–320 km/h (150– 200 mph), 283.5 km (176.2 mi) of Mini-Shinkansen lines with a maximum speed of 130 km/h (80 mph), and 10.3 km (6.4 mi) of spur lines with Shinkansen services.[5] The network presently links most major A lineup of JR West Shinkansen trains in October cities on the islands of Honshu and Kyushu, and 2008 Hakodate on northern island of Hokkaido, with an extension to Sapporo under construction and scheduled to commence in March 2031.[6] The maximum operating speed is 320 km/h (200 mph) (on a 387.5 km section of the Tōhoku Shinkansen).[7] Test runs have reached 443 km/h (275 mph) for conventional rail in 1996, and up to a world record 603 km/h (375 mph) for SCMaglev trains in April 2015.[8] The original Tōkaidō Shinkansen, connecting Tokyo, Nagoya and Osaka, three of Japan's largest cities, is one of the world's busiest high-speed rail lines.

Open Sound Data Catalog Created on 2021/04/17 19:22:02
Open Sound Data Catalog https://desktopstation.net/sounds/ Created on 2021/04/17 19:22:02 This catalog introduces a list of locomotives and sound data available on Open Sound Data, a project for distributing Japanese-style sound data for digital model railroads (DCC). Use of the data is free of charge, but compliance with the terms and conditions is required. Please refer to the Open Sound Data website for more information. Old Kokuden Type nose suspension drive Provided by MB3110A@zhengdao_X The sound of a suspended motor is something that we cannot hear around us anymore. The ESU sound decoder fulfilled my wish that the nostalgic sound of the suspension motor would remain in service forever. The sound source is based on the running sound of Tobu 3050 series, and various operation sounds such as old auxiliary equipment are added to make it highly versatile. The sound source is based on the running sound of Tobu 3050 series. This data can be used with the LokSound V4 series and LokSound 5 series, but the LokSound V4 rescue version has some limitations in sound quality and functions. URL https://desktopstation.net/sounds/osd2.html Kiha 40 series diesel car Provided by MB3110A@zhengdao_X, Tochigi General Rolling Stock Office This is the sound of the DMF15HSA internal combustion engine (original engine) used in the Kiha40 series. I wanted to preserve the sound of the original engine in a model, so I combined the sound recorded by MB3110A with my own sound. I would be happy if you could run it with the diesel sound.

Overview of Series EV-E301 Catenary and Battery-Powered Hybrid Railcar
Special edition paper Overview of Series EV-E301 Catenary and Battery-powered Hybrid Railcar Hiroshi Takiguchi* The Series EV-E301 railcar is equipped with large-capacity batteries, and it can be run in non-electrified sections. In electrified sections, the railcar can run just like ordinary EMUs by raising the pantograph, and it can charge batteries from overhead contact lines. When moving into non-electrified sections, the pantograph is lowered and the railcar runs on power from the batteries. When braking, the batteries are charged with regenerative energy so as to make effective use of electric power. Also, the railcar can make quick charges using a charging facility installed in the station. The Series EV-E301 can achieve elimination of exhaust gases from diesel engines as well as reduction of CO2 emissions and noise. •Keywords: Catenary and battery-powered hybrid railcar, Battery for traction circuit, Quick charge, Overhead contact line recognizing device, Reduction of environmental burden 1 Introduction and running tests. Using the catenary and battery-powered hybrid railcar system, Railways are said to have high energy efficiency compared with rolling stock operation between electrified and non-electrified other forms of transport. Even so, energy consumed for train lines can be unified. This will enable improvement of efficiency operation still accounts for a large percentage of the energy used of rolling stock operation, reduce labor for maintenance thanks to in railway business. It is thus an important issue for us to reduce reduction of the number and type of mechanical components of energy consumption and CO2 emissions, and railway operators engines and transmissions, eliminate exhaust gases from engines, have taken measures to improve energy conservation with rolling and reduce CO2 emissions and noise as well.

Relationship with Society
Society JR EAST GROUP CSR REPORT 2017 Relationship with Society Strengthening Collaboration with Communities The very existence of the JR East Group depends on the health of the east Japan area and of Japan as a whole. As a company responsible for a form of social infrastructure (i.e., railways), and as a member of the community, we work together with communities in order to take actions aimed at achieving their desired future. In addition, we actively implement community vitalization and tourism promotion measures that leverage the unique capabilities of our group, as well as pushing forward with the creation of appealing urban areas centering on train stations. As a member of the local community, JR East has been working to build an energetic community with a strong interest in the community's future by promoting three town development perspectives of "development of large- scale terminal stations," "establishment of a lineside brand that will be chosen Tokyo Station City (an image) by passengers" and "revitalization of core regional cities." ■Development of large-scale terminal station In Shinagawa area as a "Global Gateway Shinagawa", aiming to realize town development where advanced businesses and human resources will gather from all parts of the world and new businesses and culture will be created from various types of exchange, construction of a new station which will be the core of the new town has been launched between Shinagawa and Tamachi Stations. At Shibuya Station, with the move of a portation of the Tokyu Toyoko Line to underground tracks, we are proceeding with renewal and reorganization of the function of the station, rearrangement and expansion of surrounding infrastructure, and construction of jointly-developed buildings, in cooperation with related business operators.

Environment JR EAST GROUP CSR REPORT 2017 Environmental Conservation Activities along Railway Lines Biodiversity ■HometownForestationProgram In 2004, in order to protect biodiversity and contribute to a sustainable society, while cherishing our sense of gratitude for nature, we began the Hometown Forestation Programs to plant trees native to each region and revitalize the forests. We undertook these programs with the cooperation of Fukushima Prefecture from 2004 to 2009 and with the cooperation of Niigata Prefecture, the town of Tsunanmachi and Tokamachi and Ojiya Cities in the prefecture from 2010 to 2014. In FY2017, we began forestation activities in Naruko Hometown in Osaki City, Miyagi Prefecture. Naruko Hometown Forestation Program in September 2016 ■Forestdevelopmentalongrailwaylines☆ Beginning in 1992, we have been organizing tree planting activities along JR East railway lines. By FY2017 a total of approximately 50 thousand people had participated in planting about 343 thousand trees. Today, planting has gone beyond the trackside and is done in cooperation with local communities. ■Developmentofrailwaytrees Along some JR East railway lines, we have planted railway trees to shield the tracks from blowing snow and wind. The first railway trees were created in 1893 for disaster prevention. As living disaster prevention facilities, railway forests are playing their role. JR East now owns approximately 5.8 million railway trees on a total of about 3,900 hectares along our lines at approximately 1,080 locations. The trees absorb 15 thousand tons of CO₂, equivalent to 0.7% of the CO₂ that JR East emits (this is the actual amount in FY2017). In this way, they also contribute to preserving the environment.
