In 1974, Marx introduced a diesel freight train set it called The Allegheny, catalog #25760, that ran on AC electric power and sold through catalog retailers. If you have a Marx 25760 train set today, it’s worth considerably more than its original retail price, even adjusted for inflation.
Marx’s Allegheny train set was part of the Great American Railroads series. It had catalog number 25760 and was manufactured only in 1974. Today it is one of the most valuable Marx train sets ever made.
