A popular and well-remembered entry in TYCO offerings is the Chattanooga Choo-Choo product line. It is first found in the company’s 1975-76 catalog. TYCO designated Chattanooga-dressed pieces with a -15 suffix on the stock number and both the steam engine and caboose are listed as separately available items, in addition to the train set beginning in 1975.
Through its eleven-year run from 1972 through 1983, M*A*S*H was one of the highest-rated television shows in history. Bachmann licensed the M*A*S*H name from 20th Century-Fox for this train set that debuts in the 1983 catalog.
