The Kansas City Southern, post CPKC/PV&T Trust merger, has had its operations slowly peeled away from the CPR’s so it can become the southern district of the newly embiggened transcon. It, like the CPR, is maintaining its own dispatching, locomotive roster, numbering scheme, and explosion in a candy shop paint scheme.
CPKC only had about three years of integrating the KCS & CPR, so there is (relatively) minimal work needed to deintegrate them, at which point the roadmap to make KCS a direct Trust subsidiary with its own seat on the board.
KCS, like the CPR, has a roster that is dominated by EMD and GE power, with only about 150 ILW locomotives rostered. GE & EMD are keen to keep that dominance, so have been forced into an aggressive discounting scheme to prevent being priced out of future locomotive sales.
The Trust has directed KCSM to (re-)electrify their mainline from Ciudad de México to Querétaro, and much of that line segment has wire up again. The grand scheme is to electrify from Veracruz to Nuevo Larado, and line poles are slowly going in from Veracruz west.
The KCS has not started planning for electrification, because there are significant chunks of Union Pacific trackage rights connecting the Texas-Mexican Railway to the KCS & KCSM, and the UP is refusing to electrification over their tracks.
Despite encouragement from the LT&L, the KCS is sticking with their “Belle” colour scheme (referred, affectionately, as “candy shop vomit” but the staff of the TdM shops – themselves no stranger to complex bright colour schemes.)
