What is the approximate ratio of unmanned to total level crossings on Pakistan Railways’ operational track?

💡 Explanation:

Pakistan Railways has approximately 4,072 level crossings, with 2,731 classified as unmanned. This ratio (2731/4072) is approximately 67%, which simplifies to a 2:3 ratio of unmanned crossings to the total number of crossings. This highlights a major public safety and infrastructure challenge.
