An interesting consist makes up the CPKC 247 on this Valentines Day 2024. KCS 4844, BNSF 9783 and SOO 4448. Guess this would count as a fallen flag locomotive consist.
BNSF 6339 (ES44AC) leads the Provo to Denver train with 5 other head end units, including two Kansas City Southern engines, down the hill from Tunnel #1 and into Coal Creek Canyon, Colorado.
