on september 6, 1869, the first western pacific train reached the shores of san francisco bay at alameda terminal, thus achieving the transcontinental "pacific railroad" envisioned in the 1862 pacific railroad act. according to the "daily alta california", this first through train left sacramento at 10 am, got delayed by some construction trains, exited niles canyon late at 9:30 pm, and an hour later arrived at alameda terminal to a cheering crowd. two months later, central pacific railroad switched the western transcontinental terminus to its expanded oakland pier, which was inaugurated on november 8, 1869, in another round of celebration.
