Page "Coast Starlight" Paragraph 5

With the start of Amtrak operations on May 1, 1971, a single route was formed between Los Angeles and Seattle — and for a few months between San Diego and Seattle.

The unnamed train ran three days a week ; on the other four days ( northbound Monday, Wednesday, Thursday and Saturday and southbound Monday, Tuesday, Thursday and Saturday ) another unnamed train ran between Los Angeles and Oakland ( initially assigned 98 northbound and 99 southbound ).

Additional service was also provided between San Diego and Los Angeles and between Portland and Seattle ( those became the San Diegan and Mount Rainier / Puget Sound on November 14 ).

In the November 14, 1971 timetable, the LA-Oakland train received the Coast Daylight name that the SP had used for its LA-San Francisco train, and was extended to San Diego and assigned numbers 12 and 13.

The San Diego-Seattle train received the new name Coast Starlight and became trains 11 and 14.
