Question

anonymous · Answer

The answer is $$2\sqrt{s/a}$$

experimentx · Answer

try find the distance travelled to reach the midpoint

So the train will use it's maximum acceleration, and it's maximum deceleration to complete the journey in the shortest time. The velocity time graph would be something like this:
|dw:1338729820813:dw|
