In June 1931 progress was in earnest with the Inside Gateway link between the Great Northern and Western Pacific Railroads. The two railroads would connect with each other just west of the Big Valley community of Bieber. Byron Greenwood saw an opportunity and had a townsite laid out where the railroads would connect. He named his new enterprise Big Valley City. However, when Greenwood applied for the establishment of a post office there, postal authorities were not impressed as they frowned on three word names for post offices.
The Great Northern was not pleased and intended to name their new station, Bieber. Some one came up with a compromised name of West Bieber, but it fell flat. While it took some time to resolve the dispute, everyone, but the railroad, finally agreed to the name of Nubieber.
