I hope this would help

Hi guys here comes the game trick actually u have stuck in last compartment of Express after FBI enters train where guard will be standing outside the compartment right...... here u need get thru guard by running to next compartment passing thru laggauge room and get into third room in next compartment where u can find Gun so use it to finish guard and move on and u will find that female and then u need to reach last compartment and unhook compartment by placing one of them in last room where u can find keyboard is destroyed but still will work if u place one of them near hook un-locker on both side I guess this definetly works because i passed like this Bye.........
