General Railway Signal Company (GRS) is a supplier of railway signaling equipment, systems and services in Rochester, NY. Now a part of Alstom Transport and no longer an independent company, the Rochester site traces its history all the way back to founding in 1904. GRS was a member of the Dow Jones Industrial Average from 1928 to 1930.



General Railway Signal Company (GRS) was founded in 1904 with the merger of three companies (Pneumatic Signal Company of Rochester, New York, Taylor Signal Co. of Buffalo, New York and Standard Railroad Signal Company of Arlington, New Jersey). General Railway Signal was one of the 30 stocks when the Dow Jones Industrial Average[1] was expanded from a 20-stock average on October 1, 1928. It was replaced in the DJIA by Liggett & Myers on July 18, 1930. In 1965, General Signal Corporation (GSX) was created with the intent to diversify into areas other than railway signaling. GRS was a wholly-owned subsidiary of GSX. In 1989, GRS was acquired by the Italian company Sasib and joined the Sasib Railways group. In 1998, it became part of Alstom when Alstom acquired Sasib Railways. It is now a dependent site of Alstom Transport. The GRS name is no longer used. All products now use the Alstom brand.

In 1960, GRS opened up a division called the "General Railway Signal Company de Argentina" in Buenos Aires, Argentina, which took care of manufacturing, installing, and providing technical support of GRS railroad signalling systems in Argentina. Noticeably among their products are their railroad crossing signalling parts, branded with the GRSA logo, instead of the usual GRS one. This facility was closed down in the early 1980s.

In 1986, GRS joined with China National Railway Signal & Communication Group Corporation (CRSC) to form the Chinese-American Signal Company (CASCO) in Shanghai, China, which produces products and systems for railways in the People's Republic of China.[2]

From its founding until 1993, GRS main office and manufacturing facilities were located at 801 West Avenue in Rochester, New York. In 1993, it moved to two new suburban facilities: administration and engineering to Sawgrass Drive in Brighton, and manufacturing to John Street in West Henrietta. In 2003, the Sawgrass facility was closed and all activity was consolidated at the John Street plant, renamed Alstom Station.
