Mine Train Tunnel (Including Long Straightaway Section)

A jagged tunnel hewn from solid rock deep within the Nazi submarine base, comprising multiple sections including a long straightaway where the mine train accelerates and Nazis pursue Indy and Marion. The tunnel plunges into the base's hidden core, with dim lights flickering along damp walls, amplifying the rumble of machinery. It serves as a transport route for the mine train carrying the Ark of the Covenant, Belloq, Shliemann, and Marion, while also featuring a straight stretch where Shliemann fires his pistol and fuel drums ignite, creating a roaring fireball.
