First of all, in my opinion.. The best thing to do... is to prevent it.
Take care of your stuff people!! Before it is too late!!!
I was travelling around Europe for the last month and when I was travelling from Nice to Barcelona, it happened. We had to stop in Montpellier (an interchange station) before we can proceed to Spain. Everything happened there. On that day, our train was delayed for an hour and a half. Not only ours actually, almost all the trains were delayed because of the some railway track faults.
My mistake was that I put down my backpack behind my boyfriend's back, which was out of our line of sight. We then sat down and proceed to do something else. We kept looking at the display for any updates on the train status and also at our phones. And then when it's time to get up, I realize my bag was gone.
Guys, I hope you can learn a lesson from my mistake. Make sure to put your belongings where you can see them especially when you are out in a public area. Nobody will take care of them except you.
If however, you are a klutz like me despite the countless warnings your parents has given to you, well here comes the more formal to-do steps to make sure your travel can continue.
