The Western world leaders and public figures have been traveling together in packs on the Dorohusk, Poland to Kiev, Ukraine rail-line since the beginning of the Russian Special Military Operation. The get to the Kiev rail station where Western press snap pictures, take videos, and film interviews. Lot's of hand-shakes and hugs between Western and Ukrainian public figures. My guess is that the opinion has been that "Russia wouldn't dare to strike a train of Western dignitaries." I have no doubt that Russian intelligence knew which Western dignitaries were on the trains passing through that station. The strike on the locomotive of the train following them, imho, was a stark warning. "Take these trains between Poland and Kiev at your own peril." The next message may end up being up-close-and-personal: "Come to Kiev to engage in overt war planning to attack Russia, and you ARE a co-belligerent and a legitimate target of war." The next month or so should be interesting to watch.
