This is a 6+2 car formation of the 383 series "Shinano" with panorama cars. I've run it 2 or 3 times after installing parts, leaving only the hoses for the inter-car dampers in their original state. I haven't tried it, but there's a possibility of interference on extremely sharp curves. Removing them will result in a 500 yen discount, it's a minor detail. All accessories are included.
