The Wason Manufacturing Company was a maker of railway passenger coaches and streetcars during the 19th and early 20th century.

[3] Although the concept would later be popularized by the Pullman Company, Wason was the first to manufacture sleeping cars in America.

One of these became the personal rail car of Leland Stanford, President of the Central Pacific Railroad.

It continued to manufacture both streetcars and conventional railroad cars until 1932, when the Great Depression forced Brill to close the plant.

Philadelphia and Western #10, built by Wason in 1915, was the last street railway plow to operate in the United States.
