Tetsuwan Atom Odcinek 30: Uran and Uran

Astro and his classmates go on a field trip to see a dam and stay in a lodge. Due to a storm an upstream dam is on the point of breaking. Astro's jets fail so the party try to flee on a D51 steam locomotive kept in the lodge. An old man from the lodge, who was the automatic operating device, asks to incorporate himself into the SL. The D51 runs at full speed. With Astro's help, the D51 makes an escape from the water but the device burns out.
