Average speed = Distance ÷ Time = 240 ÷ 4 = 60 km/h

Indian Railways primarily uses Broad Gauge of 1676 mm, which covers about 63% of the total network and allows for higher speeds and carrying capacity.

New Delhi Railway Station is the busiest railway station in India by passenger traffic, handling over 400,000 passengers daily.

Total time = 6 hours, Actual travel time = 5 hours, Average speed = 360 ÷ 5 = 72 km/h. But total elapsed time is 6 hours, so 360 ÷ 7 = 51.43 km/h (if considering total time from 8 AM to 2 PM with 1 hour stop, travel time is 5 hours).

Time = Distance ÷ Speed = 1920 ÷ 80 = 24 hours = 1 day

The Vande Bharat Express operates at a scheduled speed of 160 km/h, making it the fastest train in India. It was introduced in 2019 on the Delhi-Varanasi route.
