When RTD approached UP and asked to build the "East Line" along the Limon Sub right-of-way, UP had a few conditions. Specifically, they are getting CTC installed between the yard in Denver and Mesa. A stretch of about nine miles. In addition, a second main track is being added between the yard at Roydale (about four miles). There are several locals that work between Denver and Roydale and the addition of the second main will allow through trains to get through the limits much easier and faster. In this shot, you can see new signals - not yet fully installed or activated - near the west end of Roydale at Havana Street. Here, the second main will go back down to a single main. The track closest to the photographer is not yet active, but will become Main 2 once it is active.
