Correct answer: D. all of the above
- A. distance between the stops is more
- B. maximum speed reached is high
- C. acceleration and retardation rates are low
- D. all of the above
Explanation
Main-line trains have widely spaced stops, allowing higher speeds, while their acceleration and retardation rates are lower than those required for frequent urban stops. Thus all the listed comparisons apply.
