リンリンメトロ終盤の階段で、ドリフトをしながら柵に向かってジャンプし、ホームに着地します。階段の中に入り、そこから電車に乗ることが可能です。電車は少し進んだ先で停止し、数秒後に一両ずつ開始地点へテレポートします。停止後の4両目の端は落下判定に重なっておらず、そこに留まることができます。
On the stairs near the end of Super Bell Subway, drift and jump toward the fence to land on the platform. You can then enter the stairs and board the train from there. The train stops after moving a short distance, and a few seconds later each car teleports back to the starting point one by one. After it stops, the edge of the 4th car doesn't overlap with the out of bounds, so you can stay there.
