Roseville is a city located in Placer County, California, and is part of the Greater Sacramento metropolitan area. The city was originally a stagecoach station called Griders, named after the owner of a hotel in the area. In 1864, the Central Pacific Railroad reached the area and the town was renamed Roseville, after the town's first postmaster, Roseville Grant. The railroad played a significant role in the city's growth and development, as it became a major transportation hub for freight and passengers.

Today, Roseville continues to be an important transportation center, with several major highways passing through the city, including Interstate 80 and State Route 65. The city is also home to the Union Pacific Railroad's Roseville Yard, which is one of the largest railroad yards in the world. The yard serves as a major freight transportation hub, handling a wide range of goods and commodities that are transported throughout the region and beyond.
