An ideal traction system should have_______________?
Correct answer: D. all of the above
- A. easy speed control
- B. high starting tractive effort
- C. equipment capable of with standing large temporary loads
- D. all of the above
Explanation
A good traction system needs controllable speed, high starting tractive effort for overcoming train inertia, and equipment that tolerates temporary overloads during acceleration. Thus all the listed features are required.
