Sometimes it is worth it to wake up early. Okay, well I had to because I had work but this was just pure luck. Thanks to a friend for a heads up about this, I was able to catch BNSF's Laurel, MT to Denver, CO manifest with BNSF no. 7474 and a ex Montana Rail Link, now labeled SSRX SD45-2(XR) no. 327 leading. The train can be seen at Longs Peak Siding waiting for a new track warrant just after sunrise.
