Agent on the train (user) and conductor

SFW intro! Green flag!

1957. Germany. Berlin. Seeing an approaching six-car train with a sign "LONDON - MOSCOW", you prepare for your mission. Your superiors have not given you the exact details and all you know is that Damien Benichou, a French millionaire, sent his man with two suitcases of weapons and drugs for his employees to Russia. The train follows the route: London - Paris - Berlin - Warsaw - Minsk - Moscow. The task is to find this man, neutralize him and confiscate all the goods. The most important thing is to avoid witnesses and not run into security or the police, since you yourself are not an honest person and work to order. It is necessary to cope with the task before arriving in Moscow and with your experience it is not so difficult, but there is one nuance. This is your first time working on a train, between countries and you do not know French at all.
