[Machine Translation] The Chuo Line has many faces. Commuter trains from Tokyo to Takao and express trains from Shinjuku to Matsumoto and Kofu come to mind, but the Nagoya side also has another face, with express trains to Nagano. This book introduces the changes in diesel express trains, train express trains, train limited express trains, and commuter trains from the era of steam locomotives to the 1990s. We hope you will enjoy reminiscing about the changes over the past half century in this book. ( from the preface ).
