The SCMAGLEV and Railway Park is a JR train museum located in the Port of Nagoya. Ironically, you need to take a non-JR train to get there and if you have a JR rail pass, that wont help you get in at a discount price. But if you like trains, this is a great place to visit. History documented in the museum dates back to the time of horse travel but preserved trains that date back to 1913.
Above is the interior of an train made in 1933, the Moha 1. The plastic rings are not original I think.
Above are old signs from the Taketoyo line, the train line I take daily to work. I did not understand the history of the Taketoyo line before visiting the museum. But I learned this train line existed before trains connected Tokyo to Nagoya. Supposedly the train station that I goto daily, Kamezaki, is the oldest continuously operating train station in Japan.. but this was not covered in the museum.
