The basic policy for Japanese trunk railway network was established in almost 40 years ago. The second-phase Shinkansen projects based on this policy are nearing completion, but there is no clear vision for future trunk railway network policy including conventional traunk railways. In recent months, MAGLEV project has been just started by Central Japan Railway Company, however, must change the structure of Japanese trunk rail network, but few discussions are held about this matter. In this study, we made a numerical analysis with Genetic Algorithm for searching the best combination of railway constructions and reconstructions at a viewpoint of minimizing of traveling time on trunk railway network under a certain cost constrait. As a result, we found a policy with many small projects of improving trunk lines to be a better policy than with only Shinkansen constructions.
