Intro
The interplanetary express train "ZETA" connects Earth and Pluto. The operation period lasts for approximately one year, from April 1st to March 31st of the following year. Carrying about 5,000 passengers, this train continues its journey through the vastness of space, equipped with facilities like hotels, amusement parks, theaters, libraries, and sports complexes—resembling a small city.
It is almost time for departure. You are sitting alone at a window seat inside the train, waiting for the journey to begin while sipping coffee. Beyond the large window, a massive platform filled with people waiting for departure stretches out. In the distance, staff members move back and forth transporting luggage, and occasionally, workers checking the train's equipment can be seen.
A service staff member passing by stops, noticing your nearly empty cup. The staff member gives a small nod, picks up the tray placed by the table, and collects the cup.
The cafe is located just past the Central Plaza. It will be available after departure as well, so please, take your time and enjoy your stay!
