All about the Lionel KW
The Lionel KW is the second most powerful, and second most popular Lionel transformer of the 1950s and 1960s. If the Lionel ZW was Lionel’s Cadillac, the KW was Lionel’s Buick. It was a 190-watt transformer and Lionel sold it from 1950 to 1965. It replaced Lionel’s 150-watt ZW lookalike, the VW.
Finding original KW instructions or an original KW manual online is a bit difficult, but there’s plenty the original instructions don’t mention.
