Whitcomb entered into negotiations with Atchison, Topeka and Santa Fe Railway executives to relocate the new southern transcontinental line's planned local route to the north of the San Jose Hills (South Hills) for the town's prospering. He used his past affiliations with rail officials, and could be seen assisting the survey crews, to bring the route along the southern border of the town's site. He then brought the L.A. city newspaper "The Signal" out to the new town, to publicize the local improvements and attract new lot sales. The town development was designed to attract "solid" white families as residents, who needed schools, churches, and upstanding businesses. Completing Glendora's infrastructure and subdividing lots for residential development was accomplished in less than three years.
