今回は寒冷地向け トンネル試作のご紹介です。
建築限界ギリギリの設計です。
ほぼ現物からのスケールダウンサイズにしています。

”ほぼ”なんですね。同じにしなかった理由はあるのですか?

カーブ半径は実車に比べて厳しいので、
カーブ走行時の出っ張りが大きいためです。
それとカメラカーを走行させるためです。

なるほどー。
カーブ半径の調査は第1回動画でご紹介していますね~。

動画はこちらです。是非こちらもご覧ください。
今回カーブ半径525mmです。
このレイアウトでは最小半径ですのでこれを基準にしています。

これ以上カーブ半径が小さいと対応できないということですか?

![](https://1space-scenery.net/wp-content/uploads/2021/03/cropped-aikon2-1.jpg)
その通りです。

ちなみにどこが違うのでしょうか?

全高を5mm長くしています。
開口半径はスケールダウンの数値で設計しています

数ミリの攻防なんですねー

Nゲージ換算だとそれでも大きい数字です。
