East of the Promontory Mountains, the Central Pacific and Union Pacific railroad grades crossed each other several times. In some places, they used the same grade.

Central Pacific crews finished their 10-Mile Day here, having laid 10 miles and 56 feet of track.

Here at Promontory Summit the Union Pacific and Central

Pacific rails were joined.

Central Pacific crews broke for lunch here in their race to lay the most track in one day.

Miles of track laid per day quickly became a contest between the two railroads. In early April the Union Pacific laid 8.5 miles of track in one day and then bet the Central Pacific $10,000 that they could not better the record. On April 28, 1869, the Central Pacific won the bet.

One of the Union Pacific’s most difficult areas of construction was here, as they climbed the Promontory Mountains. In the space of just eight miles, the Union Pacific blasted five cuts through solid rock, building four trestles and four fills.
