While 'fanning around Shelby, MT, I saw my first KCS ACe! Just west of CP Teton, we scooped this hot EB stacker, and some quick railfan about face and throttle work later, my wife had him bagged; and not too bad considering we were pacing at 50 MPH.... Kristal Siembida photo: When we got ahead of him, we found a nice place to park, and I snapped some shots once he stopped. A Sweetgrass, MT-bound freight was crossing over in front of him at the monster signal bridge west fo Shelby, and was headed to the international border. The stack had to stop short of the signals, providing a nice shot for me! Here's the Sweetgrass local at the signal bridge, with the stack waiting in the background: I got back into my trusty railfan mobile, and grabbed a closer place to park, and hiked out on the prairie for some better shots. Here's the nose; the candycane striped handrails take the cake!
