Lost Wallet with all important ID cards

I am a student at NUI, Maynooth. Lost my black color wallet in the train containing my College Id card, my student travel card, my bank debit card and nearly €70 cash. The train left maynooth station at 7:30 pm. I am on student visa here and losing wallet is really problematic for me as it has my GNIB card also. Please help me and in case if someone finds it, please keep the cash, and send me the cards and other important papers in it. My name and address is: ASHISH PANT 117 Ardleigh Vale, Mullingar, Co. Westmeath Mobile no. (+353-899794004)
