A turntable is used to rotate locomotives 180 degrees to change their direction without requiring them to travel backward.
# Solution: Rail Track Gauge Distance
Rail gauge refers to the distance between the inner edges of the two parallel rails on a railway track. India uses three different gauges, and broad gauge is the widest standard in use.
Step 1: Understand Rail Gauge Types
Different countries and regions use standardized rail gauges:
- Narrow gauge: \(0.6 \text{ m}\) (used in hilly terrain)
- Meter gauge: \(1.0 \text{ m}\) (used in some Indian regions)
- Broad gauge: \(1.676 \text{ m}\) (standard in India, most of Europe uses \(1.435 \text{ m}\))
Step 2: Identify Broad Gauge Specification
Broad gauge is the largest standard gauge used in India and several other countries. It is designed to provide:
- Greater stability and load-carrying capacity
- Better comfort for passengers at higher speeds
- Reduced derailment risk
Step 3: Recognize the Standard Measurement
The distance between rail tracks in broad gauge is standardized at:
This measurement is maintained uniformly across all broad gauge railway lines.
Answer: The distance between rail tracks in broad gauge is \(1.676\) meters (Option C)
Railway stations in India are classified from Category A to F. Category H does not exist in the classification system.
Railway buffers are elastic devices that absorb impact and shock during coupling and uncoupling of coaches.
EMU stands for Electric Multiple Unit, which refers to electric trains that have distributed motor units in multiple cars.
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
Anti-collision devices are safety systems designed to prevent train-to-train collisions by automatically applying brakes when necessary.
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.
