JR East is working on innovations for conventional railway lines, mainly in the greater Tokyo area, as part of its 2020 Group Management Vision—Challenge. Among these innovations, verification by running tests is essential for "development of next-generation rolling stock control systems" and "development of railway infrastructure status monitoring equipment using rolling stock in commercial operation". A test train named MUE-Train was produced to meet these needs.
Using the MUE-Train, we promoted efficient technical development. In that, we conducted tests for development of vibration control to improve ride comfort, tests for development of railway infrastructure status monitoring equipment, and other activities. We have equipped the MUE-Train with the next-generation train communication/control network and are currently testing to confirm functions such as control and status monitoring.
"MUE-Train" is a short form of "MUltipurpose Experimental Train".
- Main development projects conducted with the experimental train

- Next-generation rolling stock control system
We have commenced development of the INtegrated Train communication/control network for Evolvable Railway Operation System (INTEROS) under the development concept of improving reliability and service. Our goal is to further expand functionality development centering on four functions separated into control, status monitoring, information and wayside monitoring systems.
- Railway infrastructure status monitoring equipment using rolling stock in commercial operation
Development is ongoing for equipment to allow frequent monitoring by regular rolling stock in commercial operation that will quickly detect changes in railway infrastructure, so that this information can be utilized for maintenance. This will replace current railway infrastructure monitoring performed with special measuring vehicles and measuring equipment. Tests are on small equipment that can be installed on rolling stock to measure the status of items such as rails, overhead lines, and safety equipment (ATS).

White, representing a bright future and hope, is used for the stripe color. An image of new railway system construction where brightly shining technologies of many fields come together is expressed by block patterns gathering at the stripe and by the connected MUE letters.
