Are there behind the scenes videos of the train set construction?

The only reliable source we have is the Wikipedia entry for Mystery Train, which details the film’s plot, cast, and production background but does not mention any behind‑the‑scenes footage, especially concerning the train set. Because the source makes no reference to such material, we cannot confirm its existence. Without additional evidence, we cannot assert that any construction videos have been released or archived. Consequently, there is no known footage of the train set being built that is publicly documented.
