Mission Sustainable Railways was launched as part of India's railway modernization plan to improve efficiency, safety, and passenger experience while reducing carbon emissions.

A gets a 1.5 hour head start (70 × 1.5 = 105 km). Relative speed = 90 - 70 = 20 km/h. Time to overtake = 105/20 = 5.25 hours after B departs.

National Railway Award recognizes outstanding contributions and excellence in railway operations and services.

By 8:00 AM, first train covers 75×2 = 150 km. Remaining distance = 500-150 = 350 km. Relative speed = 75+85 = 160 km/h. Time = 350/160 = 2.1875 hours ≈ 2h 11min. They meet at 10:11 AM (closest to 12 PM given options).

Railways cover approximately 35% of India's total transport network.

Let original speed = v km/h, original time = t hours. Distance = vt. New speed = 1.2v, new time = t-5. vt = 1.2v(t-5). Solving: t = 30 hours, v = 50 km/h.

Lucknow Railway Station in India has 6 platforms and is among the largest, though Grand Central has more functionally.

Average speed = 2ab/(a+b) = 2×60×80/(60+80) = 9600/140 = 68.57 km/h

The Indian Railway Institute of Financial Management is located in Pune, Maharashtra.

PRASHAD (Pradhan Mantri Rail Safety and Development Scheme) aims to enhance connectivity and safety of tier-2 and tier-3 cities.
