In landslide-prone regions, railway networks are vulnerable to rapid flow-like landslides, which can cause extensive damage, even at significant distances from the landslide's point of origin. The prioritization of protective measures on a national scale depends on the accurate assessment of each railway segment's exposure to landslides.
