Then there's the theme of the train as a microcosm of society. All kinds of people are on the train, and their interactions can show different aspects of human nature. And of course, there are often themes related to the power and allure of the train itself, whether it's a beautiful steam engine or a high - tech modern train.
One common theme is character backstories. Writers often explore the pasts of the characters from the Bullet Train movie, like Ladybug's early days as an assassin.

Common themes in train horror stories include the idea of being trapped. Once you're on a moving train, it's not easy to just get off. So if there's a threat on the train, you're kind of stuck there. Also, there's the theme of time. Trains usually run on a schedule, but in horror stories, that schedule can go haywire. For example, the train might keep going and going without stopping at the right stations. And finally, there's the theme of the other passengers. There could be a person on the train who seems normal at first but then reveals themselves to be a monster or a threat in some way.
One common theme is secrecy. Since it's a public place, the idea of getting away with something sexual secretly is often in these stories. Another could be the element of the unexpected encounter.
