In its 19th century heyday, the city of Springfield in Massachusetts produced the first industrial assembly line, the first gasoline-powered automobile and the first sleeping rail car. Wason, one of its leading companies, made passenger coaches and streetcars for clients across the US and countries as far afield as Egypt. While Wason went out of business in the 1930s, Springfield prospered well into the 20th century before deindustrialisation forced many of its factories to close.
在19世纪的鼎盛时期,马萨诸塞州斯普林菲尔德市有了第一条工业装配线、生产了第一辆汽油动力汽车和第一节卧铺车厢。Wason是该市领先的公司之一,当时它生产的列车车厢和有轨电车不仅供应美国各地的客户,还供应远至埃及的海外客户。虽然Wason在20世纪30年代破产,但斯普林菲尔德在进入20世纪后还繁荣了很长一段时间,直到后来去工业化迫使该市许多工厂关闭。
