色々お世話になりました。 (^.^)
Thank you very much for your outstanding work. I’m looking forward to your Series 700 Shinkansen.
Regarding your lack of blueprints for the Series E5 and E7 Shinkansen maybe this site can help. These are model trains but maybe the shots are detailed enough to create a 3D model from them. I do own a few of these myself and they are very accurate.
