Like most other cities the world over, Los Angeles moved away from the inflexibility of light rail public transportation after the Second World War. An increasing emphasis on car ownership gripped the West, leading to booms in freeway construction, service station openings and closures of all sorts of rail lines, light and heavy. Most of the light rail lines of Los Angeles were replaced by bus routes – often, the lines were purchased by bus companies with the express intention of doing so.
The last of the Red Cars (operated by the Pacific Electric company) ran on the Los Angeles to Long Beach line until April 9, 1961. The last of the Yellow Cars (operated by the Los Angeles Railway company) ran almost two years longer, before the last service on the J, P, R, S and V routes on March 30. All of these were replaced by bus lines on March 31, 1963. It was the end of an era, and the start of LA’s transformation into an entirely car-based society.
