Narrative:
Navigation rerte on ground on fra (frankfort) handled by ATC flight control then filed with montreal center and recorded. Because the 2 planes were so close, montreal did not read the 2ND filing fully then left the 1ST file as is. At time of said violation the 2 courses were identical. No navigation error occurred and corrected flight path maintained.
