in an increase of $2,000,000, bringing the total to $5,000,000.
By this time, the Air Brake had been introduced suc-
cessfully on practically every mile of railroad in the United
States and had also won recognition in almest every foreign
country. The plant on the North Side was no longer
adequate to handle the increasingly heavy volume of
business and the company was forced to seek more com-
modious quarters. In order to get far enough away from
the center of Pittsburgh, that sufficient room would be
afforded for proper development, and at the same time to
realize the advantage of the best transportation facilities,
a site was selected in the Turtle Creek Valley, 14 miles
east of Pittsburgh on the main line of the Pennsylvania
Railroad. The plant was moved accordingly in 1890,
and the town of Wilmerding was established to provide
homes for as many of the employees as cared to live in the
immediate vicinity.
The Company continued to enjoy a steady growth in
its new location. In 1898, the capital stock was increased
to $11,000,000; in 1907, to $14,000,000; in 1912, to $20,000-
000, and March 15, 1817, to $30,000,000, which is the
present capitalization. During this period of expansion,
the Company developed or acquired control of a number
of other industries, engaged in the railway supply business
along lines having a natural or supplementary relationship,
prominent among which are the Union Switch & Signal
Company of Swissvale; the Locomotive Stoker Company,
North Side, Pittsburgh; the American Brake Company
of St. Louis, and the National Brake and Electric Com-
pany of Milwaukee. Companies are also operated in
Canada, England, Australia, France, Italy, Germany and
Russia. The most recent development of the Company
brought into existence the Westinghouse Union Battery
Company of Swissvale.
Although located at Wilmerding for more than thirty
years, the Westinghouse Air Brake Company has always
continued to be identified as a Pittsburgh industry and a
large number of the 6,000 employees engaged at the
Wilmerding plant reside in the several boroughs adjacent
to the city on the eastern line, or in the city proper. Sales
