Photo ID: 100495 Date Shot Photo By Wednesday, August 10, 2005 Kevin Morgan Location Times Viewed Chemical Arvada, CO 1772 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific Union Pacific has slowly been updating the signals on the Moffat with the latest-and-greatest in technology. While it is nice to see UP investing in the Moffat, it is sad to see the old D&RGW signals disappearing. On August 9, 2005, UP flipped the switch on the new signals between (and including) West Leyden and West Rocky. Here, UP 6045 East passes the new signal (and the old signals, now turned away from the track) at Chemical. Email Questions or Comments to the Webmaster or add a comment to the picture.
