[Machine Translation] JR Tokai s KiHa 85 series diesel multiple units, which once served on the Hida" and Nanki" limited express trains, were transferred to the Kyoto Tango Railway in 2023. After undergoing modifications to suit service on the Tango Railway, they were relaunched in 2024 as the KTR8500 series. In this feature, we board the Tango Relay" limited express train operated by the KTR8500 series and the KTR700 series Cycle Train to explore the Tango Railway line. Departing from Fukuchiyama the southern gateway to the KTR that connects to the JR lines the KTR8500-series trains head north on the Miyafuku Line, the powerful roar of their Cummins diesel engines echoing through the mountains. After performing a switchback at Miyazu, the train heads onto the Miyato Line, home to Amanohashidate one of Japan s Three Great Views. The Tango Relay" limited express service runs only as far as Amano; from there, it becomes a rapid train, serving local commuters as it continues on to Toyooka. After arriving in Toyooka and a brief rest, the KTR700-series Cycle Train pulls in. This time, I board a local train bound for Nishi-Maizuru. From Miyazu, the train enters the Miyazu-Maizuru Line, and shortly thereafter, it crosses the Yura River Bridge. The view, as if the train were skimming just above the river s surface, is one of the signature sights from the windows of the Tango Railway. The deep rumble of the diesel engine, the mountains, the sea, and the expansive rural landscape this film allows viewers to enjoy these nostalgic Japanese scenes alongside the view from the driver s seat. The bonus footage includes an introduction to the KTR8500 series, as well as a look back at the history of the KTR001 series, which once served as the Tango Explorer." Together, they offer a retrospective on the old and new limited-express diesel trains that have enriched the Tan-Tetsu experience.
