Solve it as part of Master of Mystery #2 – PORTO. This one was fun... started with excel, then give up and tried old fashion pen and paper (that allowed me to understand a few things for some variables), then... when the train was too large and the chance for mistakes was, well, quite big, I ended the puzzle in excel again . After trying a few combinations I got the answer.Thanks for the puzzle
