Oi Rail Yard, Rail maintenance yard in Shinagawa-ku, Tokyo, Japan

The Oi Rail Yard is a large maintenance facility in Shinagawa-ku, Tokyo, where Shinkansen trains are stored and serviced. The site has multiple tracks running side by side, large maintenance sheds, and special wash racks designed for high-speed trains.

The yard has been a key part of Japan's rail system for many decades, supporting the reliability of Shinkansen operations. It was built on an artificial island and has evolved alongside modern rail technology development.

The yard is named after its location in the Oi area and sits on an artificial island. It represents Japan's modern identity through the Shinkansen trains, which are symbols of the country's rail technology and travel culture worldwide.

The yard is an operational facility with limited public access and security measures including fences and monitoring. Visitors can observe train movements from nearby streets and overpasses, especially during early morning and late evening hours when activity is quieter.

The facility occasionally hosts the Doctor Yellow, a special yellow train that runs only during low-traffic periods to inspect tracks and signals for safety. These rare yellow trains are prized by railway enthusiasts and photographers for their distinctive appearance.
