K-Line was a manufacturer of O gauge electric trains and accessories from approximately 1980 to 2010. Its scrappy, value-oriented approach to the hobby endeared K-Line trains to many of its customers.
K-Line Electric Trains and Lionel tended to target one another in their advertisements. They referred to one another as “Brand K” and “Brand L.” In 2005, the rivalry turned to litigation, which eventually resulted in K-Line admitting wrongdoing, going out of business, and Lionel licensing and selling products under the K-Line name from 2006 to 2010.
