The Union Pacific Station was built during the time when trains were the fastest mode of transportation. You will see the building at 400 West, now housing Union Pacific offices and a depot. The lobby of the building is called the Grand Hall. It is open to visitors who wish to see the unique murals depicting both the Golden Spike and the arrival of some Mormon pioneers in the area in 1869. Originally named as The Union Station, the building is now listed in the National Register of Historic Places.

The building is made of sandstone, and was constructed with French Second Empire style architecture. It includes some stained glass windows and a terrazzo floor. In 2006, at least three floors of the old building were converted into a restaurant called The Depot. The said restaurant features a variety of music for the people in the City of Salt Lake.
