PROMONTORY, Utah (AP) — Utah has long celebrated the completion of the transcontinental railroad in the town of Promontory, when a golden spike was driven into the tracks in 1869.

But a Colorado museum curator is challenging that legacy, arguing the railroad wasn't completed until the next year in Strasburg, Colorado. Cliff Smith is the curator at Strasburg's Comanche Crossing Museum. Smith says the rail line running through Utah had a gap in Omaha. No bridge crossed the Missouri River and passengers had to disembark and cross the river in a ferry before getting back on another train.

Smith says the first transcontinental railroad was actually completed in Strasburg in 1870. The Comanche Crossing Museum commemorates that link and Smith says he hopes it will one day win recognition from the National Park Service.
