It had been two months since work had started on the narrow gauge railway. By now the railway is complete and has been opened. This railway has a direct connection between the Kappa Valley and the Moriya Shrine. The line goes into a forest west of Kappa Valley where a type of station called a Halt lies beside the line. The line then loops around back to Kappa Valley. A line goes into the mountains where a slate quarry was built. There are three engines that work the railway, Stanley, Albert, And the Kerr Stuart 0-4-2 Tattoo, Jun'ya Ota.

On opening day, Remilia announced the railway open alongside Yukari Yakumo, Nitori Kawashiro (who drove the first train), and the inhabitants of the Moriya Shrine, Kanako Yasaka, Sanae Kochiya, and Suwako Moriya, all of whom took the first train. Yuugi Hoshiguma also helped to open the slate mine by digging up the first slate and loading the first truck.

The engines all worked hard during the first few days of the railway, that's when the Thin Shrine Maiden came to write some stories of the little engines, these are the tales the narrow gauge railway brings.
