[Machine Translation] The Nankai Electric Railway Series 6000 was introduced in 1962 and has been in service on the Koya Line for over 60 years. It was the first 20-meter class all-stainless steel train in Japan, and is known by the nickname "Rustless Tetsujin (iron man)" because of its corrugated plate (corrugated plate) body, which is a technology developed by the U.S. company Budd. In this work, the train was reissued in September 2023 in its original stainless steel, unpainted form. The film includes a round trip on the Koya Line between Namba and Hashimoto, which is a flat section of the line, on a rapid express train. The train departs from Namba and runs on the double track section. On the way, the train passes by Rapito trains as it splits off from the Nankai Main Line and proceeds to the Koya Line. The train heads for Hashimoto with a powerful, rapid express train-like performance that gives no hint of the train's history. The smooth acceleration and distinctive clattering sound of the train's vernier control during departure and acceleration/deceleration enhances the sense of realism of the train. After passing through Chiyoda Station, the train passes by the Chiyoda Inspection District, where many trains are lined up, and soon reaches Mikkaichi-cho. From here onward, the train passes through the Kimi Tunnel, which is a flat section with a maximum height of 33 , and enters Wakayama Prefecture at the Shin-Kimi Tunnel. Approaching Hashimoto, the train runs parallel to the JR Wakayama Line and arrives at Hashimoto, the entrance to the World Heritage Kurokawa Road. After connecting with a train bound for Gokurakubashi, the return trip heads back to Namba with the top number 6001 train in the lead. The special video features include an introduction to the Nankai Electric Railway Series 6000 (6001 + 6907) train type, under-floor equipment, interior decorations, and the driver's cab, all of which will be of interest to fans of the series.
