The first one is Oigawa Main Line, which starts at JR Kanaya Station and ends at Senzu Station as the last one. Next to Kanaya Station is Shin-Kanaya Station, which is where the steam locomotive takes off, bound for Senzu Station. It is very popular, so all seats during weekends often get reserved and sold out very quickly! You can reach Kanaya Station from Tokyo in about 2 hours by train, and in 2 and a half hours by Shinkansen and train from Osaka.

The second line is Oigawa Railway Ikawa Line, with Okuoikojo as one of its stations. The train runs from Senzu Station to Ikawa Station. Here you can see the only Abt system rack railway in Japan.

The Abt system is a type of railway with a special, gear-like rail (“rack rail”) that spreads between two usual rails on which an electric train with an appropriate gear-like rail on its bottom (“rack gear”), runs. The two gear rails mash perfectly, which allows the train to go up and down steep slopes. This train runs on the steepest railway in Japan.

You can also gaze out at the exceptionally beautiful scenery of valleys, dams, and emerald lakes from the train windows. Both steam locomotive and the Abt system railway is a must-try for anyone interested in trains.

After a while, you should arrive at Abt Ichishiro Station, which follows Okuizumi Station. The tracks between Abt Ichishiro Station and the following, Nagashima Dam Station, is the steepest railway section in Japan.

As soon as the train is connected to the locomotive, it is ready to head on to the next station. The train climbs on the rails on a slope across the dam.

By the way, trains in Japan can climb up to 25 meters high per 1000 meters. This is equal to an angle of 1.4 degrees. 1.4 degrees may not seem like a lot, but ordinary trains can only run smoothly and without difficulties up to this angle.

However, this Ikawa Line has an angle of almost 5.1 degrees. It is a steep challenge for a train to climb. The Abt system is implemented to help the trains run safely over the steep sections. If you take a look back through the window, you will be able to see the rare sight of the slope.

As soon as the train has climbed all the way up, it turns a little, allowing you to glance over the steep section in one sweep. You’ll be amazed at the angle of the slope on which the rails go. It is truly a rare sight you won’t forget!
