There's an expression in English that might preserve this concept a bit: "train of thought." For example, "All that racket is interrupting my train of thought." Where "train of thought" means "what I am thinking about right now." I wouldn't be surprised is the two expressions were related somehow. I wouldn't be surprised if the vehicle train was derived from an earier meaning of "train" which simply meant any number of things that were both connected and moving.
In the French it came to be used to describe temporally related actions.
In the English it came to be used to describe temporally related thoughts.
And in the case of the vehicle, if refers to physically connected moving objects.
