On the Way to the Mansion

Around four kilometers from the south gate, the fifty-meter-wide railroad began to curve. A moment later, the train ran on the tracks five kilometers parallel with the Outer Wall and seemed to be circling around the forest. 

The entirety of the railroad had monster repelling lamps along its length. However, unlike the half-kilometer-wide main road, the repellants completely ward off monsters of any level within the area of one kilometer from both sides of the railroad. 

Approximately ten minutes later, the train had taken a U-turn, perpendicularly passing over the east and north gates, and the rail track finally met up with the other track. The train had been going westward. By the way, the other track at the station was for parking the trains.
