A train of incredible size, both in length and height, moves along the railways of Northern Zebrica. How long has it been moving forward? Where does coal come from to keep the train moving? Who is the driver? What happens if this train collides with another one? Is unknown

However, it is rumored that each carriage is an absolutely unique society. The only connection between them is not love for any power. One zebra has relatively recently joined the habitat on this train. And this is his most ordinary day here. Well, maybe a little unusual. Just a little bit.
