Post-war Era

Lionel resumed producing toy trains in late 1945, replacing their original product line with less-colorful, but more realistic trains and concentrating exclusively on O-gauge trains. Many of Lionel's models had a new feature: smoke, produced by dropping a smoke pellet or a special oil into the locomotive's smokestack.The last year of the Post-War Era was 1969, when the Lionel Corporation entered bankruptcy.
