Regular freight and passenger trains began operating over the first 31 miles of Central Pacific's line to Newcastle on June 10, 1864, when political opposition and lack of money stopped further construction during that mild winter. Construction was resumed in April 1865.

At this point, stagecoaches transferred passengers from the Dutch Flat Wagon Road.
