Preserved and displayed in Johoku Traffic Park in Itabashi Ward. This locomotive came from the Arida Railway to the Tobu Railway, but because it was underpowered, it was pushed off to the side. It's a valuable locomotive built in the Meiji era. You can go inside it. The brick-style surroundings also add a nice touch.

I went a year ago. When it was featured on a blog about 10 years ago it was falling apart, but now it's been nicely restored, which is great. Also, Koppel brings to mind lots of narrow-gauge steam locomotives like 762mm, but this Baby Loco No. 1 is 1067mm narrow gauge, so it's quite refreshing.

This is the Baby Loco, displayed at Itabashi Ward's Johoku Traffic Park.
