After they have finished recovering, the travelers board a train with their other vehicles attached to it, and make a second attempt at running over a summit: this time, the Jungfrau. Getting higher and higher every minute, with dirigible balloons tied to the train, they rise into space and are swallowed by the Sun. The travelers land with a crash on the Sun's surface. They are happy to be alive, but the heat is too much for them. Crazyloff directs the travelers to seek shelter in the train's gigantic icebox, but this plan goes too far in the other direction: moments later, the whole group has been frozen solid. Crazyloff finds a bundle of straw among the debris and starts a fire on the surface of the Sun to melt the ice. The travelers thaw out and are happily shepherded into the expedition's submarine. Crazyloff launches it off a cliff on the Sun, and it plummets through space to fall into an ocean on Earth.
