Japan Builds a New Future for the Railway

On October 1, 1964, trains began running on a new line between Tokyo and Shin-Osaka. The Tōkaidō Shinkansen opened just before the Tokyo Olympics, giving international visitors a memorable image of postwar Japan. Its rounded train noses quickly became shorthand for speed. Yet the achievement was not simply a faster locomotive placed on an old railway. It was a coordinated system of track, power, signaling, vehicles and operating practices built to work together.

The corridor between Tokyo and Osaka already carried intense traffic through some of Japan’s most important urban and industrial areas. Increasing capacity was a practical problem, not only a matter of national prestige. A new route allowed passenger services to operate without the same constraints as the existing mixed railway. Dedicated infrastructure was expensive and required difficult decisions, but it made higher-speed service possible on a scale that incremental changes to the old line could not easily deliver.
