What would have happened if I had caught the correct train?

What would have happened if I had caught the correct train? Lisbon, 1991. I had spent a fortnight in Portugal and I really enjoyed the people, the food, the landscape and the monuments. The holidays were over and I had to come back again. I had bought the return ticket in advance but I made a terrible mistake. The train had was scheduled to depart at 1:15 a.m. from Santa Apolonia Station but I was wrong and mistaken because I thought that the departure time was at 1.15 p.m. As a result I lost missed the train and the company did would not refund the money to me. It was my fault of course. Obviously I had to buy another train ticket to Madrid for the next night. But my mistake had a prize (or reward): the wonderful girl who was sitting in front of me in the wagon (or carriage) is today now my wife and the mother of my sons.

Very nice. Only a couple of corrections in red, plus some suggestions to sound more natural in blue/grey.
