Finally, on the left of the main panel there are two boxes — with food and first-aid kits. As you can see, one person is sitting in the car. Stand next to him. You will see the two scales — red and yellow. Red shows the level of health, yellow — satiety.
If satiety falls, the person begins to lose health. If he loses health, then it dies. In this case, you will not get a reward at the end of the act.
A person can lose health from hunger (if you need to bring him food from the box) or by bleeding (if you need to give him a first aid kit from a different box). First-aid kits, you can either find on the locations, either buy or craft. The food can not be crafted, it can only be bought or found at locations.
When you arrive, the lever is lowered at the beginning of the train. It appears appropriate inscription.
Go right and talk to the man standing (reading the newspaper).
He will be your second passenger. Enter the building, go upstairs. Chef no blue cabinet locked.

Speak to him, open the drawer to the right and remove the key. With the key come back. Upstairs open blue closet and pull out the access code. When he appears on the screen, then back to the train. Enter the code on the panel to continue the journey.
