Approximately 2 years.
the Chinese chipped their way through the Sierra Nevada Mountains and they hung from baskets when they did it. they were a big help to the dangerous job of building the Transcontinental railroad.
The transcontinental railroad crossed the Rocky Mountains and the Sierra Nevada mountain ranges. These ranges presented significant challenges to railroad construction due to their rugged terrain and elevation.
It was used to blow through the Sierra Mountain range in Nevada
It crossied the Sierra Nevada Range and the Rocky Mountains and was joined on 10 May 1869 at Promontory Point, Utah
Sierra Nevada is one of the stops.
It was difficult because of the harsh weather conditions and because of geography. Since it was really bad snow then the workers had to work harder. Geography because of the mountains they had to make holes in the mountains to let the train go through but they had to make sure it would not caluple.

The building of the transcontinental railroad faced challenges due to the rugged terrain of the Rocky Mountains and Sierra Nevada as well as the vast expanses of deserts and plains. The construction crews had to navigate through steep grades, harsh weather conditions, and limited access to resources, making the project a formidable undertaking.
Around 10,000 Chinese workers helped build the Central Pacific Railroad as part of the Transcontinental Railroad project in the United States during the 1860s. They played a significant role in the construction of the railroad, especially through the difficult and dangerous work in the Sierra Nevada mountains.

The Sierra Nevada mountains.
Building the transcontinental railroad was challenging due to geographic obstacles such as the Sierra Nevada and Rocky Mountains, vast expanses of desert, and harsh weather conditions. These obstacles required extensive and innovative engineering solutions to lay down tracks across rugged terrain and varying landscapes.
