These three photographs show the Union Depot in Bartlesville, Oklahoma. This mission-style depot, built in 1909, served the Atchison, Topeka and Santa Fe Railway Company and the Missouri, Kansas and Texas Railroad, (M-K-T or Katy), until 1971 when passenger service came to an end. The first image shows the exterior of the depot while images two and three show the passenger and office section of the depot. Today, the facility is the home of the Bartlesville Regional Chamber of Commerce and the Bartlesville Development Corporation.
