5 or the 5 Car was a streetcar line operated by the Los Angeles Railway, later named the Los Angeles Transit Lines, and by the Los Angeles Metropolitan Transit Authority. From 1920 to 1932, this route was known as the E Car. This was changed as part of a method to distinguish routes that lacked loops at their termini. Consequently, the 5 Car was unique during the LAMTA era in that it did not use PCC streetcars. It used buses from 1955 to 1964, transferring from LATL in 1958, then splitting the line in two in 1961, until all lines were turned over to SCRTD in August 1964.
