Pacific City Lines was a company formed in 1937 as a subsidiary to National City Lines in Oakland, California. Its function was to purchase streetcar systems in the western United States as part of what became known as the Great American streetcar scandal. General Motors made investments in 1938.
The company was merged into National City Lines in 1948.
NCL executives decided to push streetcar replacement efforts west. To do this a new subsidiary, Pacific City Lines was formed. If anyone would know how to come up with financial backing, it would be PCL executive Glenn Traer, who had been a successful Minneapolis investment banker. He and another financial expert, Matthew Robinson, prevented creditors from pulling the plug on the overextended Greyhound in the first full Depression year of 1930.
National City Lines and Pacific City Lines merged in 1948 and continued their practice of "bustitution."
