《城市如何持续流动｜斯图加特有轨电车博物馆》
德国田野调查第二站，我进入了斯图加特有轨电车博物馆。这里保存的，不只是几台旧电车，而是一整座山城如何一百五十多年都没有停止流动。从马车铁路、票务系统、城市轨道，到维修文明与后台系统，我第一次这么清楚地看到：真正成熟的城市，最后研究的，不是如何更快，而是系统老了之后，如何继续运行。 During my second fieldwork stop in Germany, I visited the Stuttgart Tramway Museum. What is preserved here is not merely a collection of historic trams, but the long-term urban backstage system that has kept a mountain city moving for more than 150 years. From horse-drawn railways, ticket systems, and urban tram networks to maintenance culture and infrastructure management, this museum reveals a deeper question behind modern mobility: a mature city is not defined by speed alone, but by its ability to keep old systems running long after they age.
