ㄉㄨㄉㄨ列車是一款包含了科學、旅遊與文化的兒童教具。
利用導電油墨繪製迴路讓建築物亮起燈因而光透過紙張出現形狀和陰影、透過磁力相斥與相吸讓列車向前行駛及光與色彩的反射使站牌的文字浮現，三大科學理論的結合及自由拼接的軌道，在實作的過程中促進學童自主學習並探索科學領域的浩瀚。
整體以扁平風格為主加上明亮鮮豔的色彩，建築的構成用摺紙、卡榫的方式，外觀參考於實際車站與景點的模樣，以此訓練兒童對立體造型的基礎概念和台灣當地文化特色的小知識，透過簡易的結構組成勉勵兒童、增進手部肌肉的掌控能力。
將科學融入生活中，在學習的同時體會手作的樂趣，以此方式提高兒童專注力且提升兒童對科學領域的憧憬和興趣。在兒童操作時家長也可以一旁教導孩一起摺紙與實驗，以增進親子間的互動。

The use of conductive ink to draw circuits to light up buildings, resulting in shapes and shadows of light passing through paper, repulsion and attraction through magnetic forces to drive trains forward, and reflection of light and color to make the text of station signs appear. The combination of three scientific theories and freely spliced tracks promote independent learning and exploration of the vastness of the scientific field in the process of implementation.
The overall style is mainly flat with bright and vibrant colors. The composition of the building is made up of origami and tenons, and the appearance is based on the appearance of actual stations and scenic spots. This trains children's basic concepts of three-dimensional modeling and local cultural characteristics in Taiwan. Through simple structural composition, it encourages children and enhances their ability to control hand muscles.
Integrating science into daily life, experiencing the joy of manual work while learning, can enhance children's focus and enhance their aspirations and interests in the field of science. Parents can also teach their children how to fold paper and experiment together while they are operating, in order to enhance parent-child interaction.
