Colorado Special Triple Action Freight 
This set is included as a new item in Life-Like's 1976 catalog and the bicentennial year is its only appearance.  The set's basic contents and stock number returns under the name Allegheny Actionmaster in 1977.  The set box featured in the background appears to be a mock up done for the catalog.
