Toy Train/Open - USA, 1986 

A Soft Drink driving a train with a tender of McNuggets? I mean sure, why not.
The black "open" section at the end with music, and referred to in the title was there for local stores to add their own message to the commercial.
Transferred from a low band U-matic tape in my collection.
Slate gives a date of March 27, 1986.
