Photo ID: 112381 Date Shot Photo By Saturday, May 3, 2025 Kevin Morgan Location Times Viewed CP RG677 (Rio (Crossover)) Utah County, UT 90 (Add a Comment) Subdivision Railroad Provo (UP) BNSF Between Springville and Gilluly, a distance of 34 miles, there are three crossovers. At Castilla and Narrows, the crossover would take a train from running on the lefthand main to the righthand main. Rio, in between Castilla and Narrows, would allow a train to cross from the righthand main to the lefthand main. Here at Rio, BNSF's Denver-Provo is already on the lefthand main (from the train point-of-view), Main 2, as it heads west. Email Questions or Comments to the Webmaster or add a comment to the picture.
