Pathologic 2

On day 2 towards the evening you will get a notification that "some evenings children gather at the station". Once you meet up with them, talk to the boy on the far left who will tell you about train summoning. He will then give you a choice of 4 adjectives used to describe the train you want to come. Remember the choice you selected. He will then tell you to go down to the end of the train track that slightly curves towards the steppe. If you open your map, it's the farthest on the left past murky's corner and the rock formation. Once you get there, equip your headset mic to your controller or PC. Stand with the wooden barrier to your back and say the word you chose outloud into the mic. Wait for a second and something neat will happen and the achievement will pop.
