The standard height of railway platforms in India is 750 mm (2 feet 6 inches) from rail level.
Total distance = (75×4) + (60×2) = 300 + 120 = 420 km. Total time = 6 hours. Average speed = 420/6 = 70 km/h
The Northern Railway zone has the largest route length among all railway zones in India.
Anti-collision devices are safety systems designed to prevent train-to-train collisions by automatically applying brakes when necessary.
Percentage increase = [(90-60)/60] × 100 = (30/60) × 100 = 50%
PWAY stands for Permanent Way, which refers to the railway track structure including rails, sleepers, and ballast.
A turntable is a rotating platform used in railway yards to turn locomotives and wagons for repositioning without reversing.
Average speed = Total distance / Total time = 360 km / 12 hours = 30 km/h
The maximum speed limit for narrow gauge trains in India is typically 80 km/h due to track specifications.
Railway crossings include level crossings, grade separations, and diagonal crossings. Overhead crossing is not a standard railway crossing type.
