Did KCS influence TFM before the merger?

Looking at TFM’s Paint Scheme, I’m wondering if KCS had influence over it before they bought it. Their paint schemes look very similer.

KCS had an approx 37% ownership in TFM since they privatized, hence the influence you mention. Groupo TMM (aka Pepe Serano) owned another significant part and the govt retained approx 25%. The KCS then recently bought the Groupo TMM portion, giving them majority control.
