The Western Pacific Railroad then began to construct its line from San Jose northward. By early 1865, after Chinese laborers had helped complete the San Francisco and San Jose Railroad in 1864, a force of 500 Chinese laborers was grading the roadbed and laying tracks for the Western Pacific. By October 1866 Western Pacific had laid of track north and east from San Jose, reaching halfway into Alameda Cañon (now Niles Canyon) to a point just beyond Farwell. The first cars left San Jose to Vallejo Canyon (Alameda Cañon) on October 2. It had also laid out the rest of the line through Alameda Cañon, through Livermore Valley, over Livermore Pass (now Altamont Pass), and on to Stockton and Sacramento, before running out of money and halting all construction. Part of the difficulty was that federal land grants were not available where Mexican land grants had previously been made.
