General Railway Signal Company (GRS) was a supplier of railway signaling equipment, systems and services in the Rochester, New York area. The company was established in 1904 and became part of Alstom Transport in 1998. GRS was a member of the Dow Jones Industrial Average from 1928 to 1930.

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). In 1923 GRS acquired the Federal Signal Company of Albany, New York.

General Railway Signal was one of the 30 stocks when the Dow Jones Industrial Average 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 1960, GRS opened up a division called the "General Railway Signal Company de Argentina" (GRSA) in Buenos Aires, which took care of manufacturing, installing, and providing technical support of GRS railroad signalling systems in Argentina. Some of local railroad lines that were provided with GRSA products were Belgrano Norte, Belgrano Sur, Urquiza and Sarmiento. Most of the signals are still active. 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.
