The Shinano Railway is owned by the Nagano Prefecture government and was created in 1997 when JR abandoned 65 km of the Shin'etsu line between Karuizawa and Shinonoi.
The 115 series dates from the 1960's and has been used on many JR lines with over 1900 units being built.
Modeling these trains
Tomix # 92415 is a 3 car set of the red Shinano Railway 115 that came out a couple of years ago but is sold out now. When I got home I found one on ebay but the price was way over list and more than I was willing to pay.
Hope this gets here in time to run on the layout we are doing in mid September.
