Ticket to Ride

You must end a match with zero trains left. You start with 45, and the game will give everyone one more turn as soon as someone has two or fewer trains left. This is done easier if you give yourself 60 cards at the beginning of the match instead of stopping at 44. Simply plan your last few moves such that you will end exactly at zero, with your last railway being at least two in length so that you don't run out of turns. 

The achievement will unlock after the final scores are displayed.
