Mountains - and the need to dig tunnels.
According to Historians, Union Pacific won the great race into Utah beating Central Pacific Railroads; however, Union Pacific paid a heavy cost. Many lives were lost as a result and a lot of money was spent on labor and materials to complete the project faster than Central Pacific.
Pacific Time is two hours earlier than Central Time, so 11:30 Central is 9:30 Pacific.
The Pacific Time Zone is 2 hours behind Central Time Zone.
The Union Pacific's progress across the Great Plains was faster primarily due to the relatively flat terrain and more favorable weather conditions, which allowed for easier construction of the railroad. In contrast, the Central Pacific faced significant challenges in the Sierra Nevada mountains, including rugged landscapes, harsh weather, and the need for complex engineering solutions like tunnels and bridges. Additionally, the Union Pacific had access to a larger labor force and resources in the plains, further accelerating their construction efforts.

The Mountain time zone is between the Pacific and the Central time zones.
If it's 6 AM Pacific Time, then it's 8 AM Central Time. The U.S. has four main time zones. From west to east, they are: Pacific Time, Mountain Time, Central Time, and Eastern Time. Each is one hour later than the last. For example, if it's 8 PM Pacific Time, then it's 9 PM Mountain Time, 10 PM Central Time, and 11 PM Eastern Time.
Noon Central Time is 10 AM Pacific Time. Midnight Central Time is 10 PM Pacific Time. The U.S. has four main time zones. From west to east, they are: Pacific Time, Mountain Time, Central Time, and Eastern Time. Each is one hour later than the last. For example, if it's 3 PM Pacific Time, then it's 4 PM Mountain Time, 5 PM Central Time, and 6 PM Eastern Time.
