In the train's frame of reference you are using proper time, not Earth's frame of reference which is time dilated. Since proper time runs faster then the time in the Earth's frame of reference this accounts for the length contraction in the train's frame of reference (as distance= velocity X proper time).
You are adding fuel based on proper time not on Earth's dilated time.
