The Lake Shore was a long-distance passenger train operated by Amtrak between Chicago and New York via Cleveland, Ohio. The Lake Shore's route paralleled that of the New York Central's famed Lake Shore Limited. Amtrak introduced the Lake Shore on May 10, 1971, nine days after Amtrak had assumed control of most private-sector passenger train operations in the United States of America. The Lake Shore was the only train to serve Cleveland, which had been the largest city left out of the original system. Amtrak introduced the route on the understanding that Ohio and New York would assume two-thirds of the cost of the train.
