Question:
The function of a gradient in train movement is to _______.
The function of a gradient in train movement is to _______.
Show Hint
Gradient modifies train resistance — more pull needed uphill, less downhill.
Updated On: Jun 24, 2025
- Increase braking force
- Increase rolling resistance
- Reduce tractive effort requirement
- Add or subtract from train resistance
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Effect of gradient
A gradient (slope) affects the load on the locomotive:
- Uphill gradient increases required force
- Downhill reduces it Step 2: How it's modeled
Gradient is treated as an additional resistance or assistance to motion. It modifies total train resistance.
Step 3: Directional impact
Positive gradient → adds resistance
Negative gradient → subtracts resistance
