I’m sorry, but there is nothing more that you can do here. It appears that all three passengers aboard this train were killed by the impact following its derailment. Based on your description of their remains, particularly the clothing of the eldest male individual, these persons are likely the Revered HaKiRozTuVa and two of his associates.
While your altruistic impulses are appreciated, continued inspection of the accident site may jeopardize criminal investigation. Furthermore, your injuries may worsen if you do not receive medical help soon. Please return to the tracks and wait for authorities to arrive.
