Technically it may have something to do with einstein's theory of relativity - it all depends on the location & velocity of the time keeper relative to the direction of the train's travel.
I guess to have the question layed out better, the time keeper should be positioned in the train to ensure we can rule out einstein's relativity theory interfering with the answer
