As the train chugged along, it passed by fields of green, forests of tall trees, and small towns dotted with houses and shops. Occasionally, it would stop at a station, and people would get on or off, carrying suitcases or bags.
The train conductor walked up and down the aisles, checking tickets and making sure everything was in order. He announced the upcoming stops, the estimated arrival time, and reminded passengers to keep their belongings with them at all times.
