The original locomotive was active and loved by the locals for 67 years from 1888. It came to be known as “Botchan Ressha” after the main character of a famous novel by Soseki Natsume. The original steam locomotives puffing black smoke have been remodelled as diesel-powered replicas. Drivers dress as they did 100 years ago transporting visitors back to an earlier era. The train runs from Matsuyama city centre to Dogo Onsen offering passengers a nostalgic ride and a view of town from the train window. One of Japan’s leading novelists, Sōseki Natsume wrote the novel Botchan based on his own experience teaching at a junior high school in Matsuyama. The steam engines that appear in the novel ran in the city for 67 years from 1888. The trains that run today are diesel replicas introduced in 2001. They take their name from Sōseki’s novel, and their old-fashioned appearance is very popular with visitors to Matsuyama. The guard’s uniforms are also replicas of contemporary uniforms.Senza tradurre tutto per chi non ha affinità con l'inglese: si tratta infatti di replica diesel, introdotta nel 2001 e che va a riprodurre (quantomeno esteticamente, ovvio) l'originale a vapore, a sua volta introdotta nel 1888 e in servizio per 67 anni.
Il nome “Botchan Ressha” deriva dal romanzo (da noi tradotto come "Il signorino") dello scrittore Sōseki Natsume
