True the 80s were a time when Lionel came out with entirely new items not just repackaged / repainted same old same old F3 sets GP7/GP9 sets and Baby Hudson Sets. THis SD40 was entirely new in that era.Late 80s brought us more new items Lackawanna MU cars, Scale Hudson and Semi Scale switcher with the semi-scale cars of the 1940 era plus 2 new ones It was the start of a new direction for Lionel
