1. Overview of DX promotion in the design and construction of railway equipment JR East is promoting operational efficiency in processes ranging from the design and construction of railway equipment to equipment maintenance and management by utilizing point cloud data and BIM models.
Until now, railway equipment inspections had to be carried out during limited hours at night by civil engineering, electric power, signalling, etc. personnel who conducted measurements and considered installation locations on-site each time construction was designed. In the future, it will be possible to perform measurements and study on a desk by using point cloud data captured by 3D laser scanners and cameras, as well as BIM models created based on that data. This will minimize the need to go to the site, which will lead to more efficient operations. In addition, regarding the design of railway equipment, until now the necessary drawings and technical study materials were created and managed separately, but by creating a BIM model, various drawings and materials can be automatically created and production We aim to improve sexual performance.

Overview of DX promotion for railway equipment design and construction 2. Regarding railway electrical equipment design using “Railway-Eye” (1) Regarding use in the field survey and design stage
Since 2022, we have been using the railway electrical equipment design tool “Railway-Eye” to conduct 3D modeling, dimensional measurements, and layout studies.
This time, by creating a BIM model that adds equipment specifications (standards, specifications, manufacturing date, manufacturer, etc.) and environmental conditions (wind speed, temperature, etc.) to the 3D model, we will be able to A function to automatically create design documents has been added. Even if changes occur in design conditions or design content, all design documents will be linked and changed by modifying the BIM model data. In addition, even when changes occur to the construction plan, it is possible to omit on-site surveys by using the point cloud data that has already been acquired.
Utilizing these functions, we aim to reduce work time by approximately 20% in design work such as drawing creation and technical
consideration.

Utilizing “Railway-Eye” at the on-site survey and design stage (2) Regarding use in considering installation location (confirming visibility of traffic lights, etc.)
In railways, train drivers check the signals at predetermined locations, so it is important to install the signals at appropriate locations and ensure visibility.
Until now, when constructing new or improving traffic lights, in order to check the signals from the driver’s perspective, it was necessary to set up a stepladder on the tracks at night to recreate the same line of sight, which required a lot of effort and time. was on. In the future, by acquiring on-site point cloud data and importing it into “Railway-Eye,” and arranging new traffic signal locations as a BIM model, “Railway-Eye” will be able to check the location of the driver from a predetermined location. It will be. Additionally, since it automatically recognizes obstructing objects, it is possible to adjust the installation position within the system.

Utilization of “Railway-Eye” when checking visibility of traffic lights 3. Regarding the promotion of DX in the design and construction of railway equipment and equipment maintenance and management ~ Regarding the operation of the common data platform ~
Currently, we are promoting the use of point cloud data and BIM models in each department in processes ranging from the design and
construction of railway equipment to equipment maintenance and management. We are currently promoting the use of point cloud data and BIM models in each department in processes ranging from the design and construction of railway equipment to equipment maintenance and management.
In the future, we will promote further DX so that point cloud data and BIM models can be mutually utilized between departments on the newly built in-house common data platform to enable smoother visualization of construction plans and process management. To do. In addition, we will improve the level of equipment maintenance and management by utilizing AI and other technologies to understand the equipment condition by comparing it with past data.
Through these efforts, we will provide high-quality railway services and improve the quality of customer service.
