The North Tarrytown Assembly was an automobile factory in North Tarrytown, New York now known as Sleepy Hollow, situated on the Hudson River. Originally opened by the Stanley Steam Car Company in 1896, the plant was acquired by Maxwell-Briscoe in 1903 from the Ingersoll-Rand Drill Company. In 1913 Maxwell-Briscoe was renamed Maxwell Automobile Company. Separate portions of the complex were acquired by Chevrolet in 1914 and 1915. At this time Chevrolet was an independent company and not yet part of General Motors. In 1918 Chevrolet was integrated into General Motors.
A range of General Motors products were assembled in Tarrytown over the years; most were Chevrolet products, starting with the Chevrolet Series 490. Its last vehicles produced were GM's second generation minivans. These were the Chevrolet Lumina APV, Pontiac TranSport, and Oldsmobile Silhouette, but sluggish sales spelled the end for GM's Tarrytown operations with its 2100 employees. It was closed at the end of June 1996 when production of minivans was moved to Doraville Assembly in Georgia.Metro-North Railroad's Hudson Line runs through the property, and some of the siding tracks that used to serve the factory have been taken over by Metro-North as overflow storage tracks for Maintenance of Way equipment.
Plants operated under Chevrolet Assembly management prior to General Motors Assembly Division management (most established pre-1945). Framingham, Massachusetts is unusual in that it changed from Buick-Oldsmobile-Pontiac Assembly management to Chevy management prior to becoming GMAD. Most of the factories were Chevrolet before GM acquired the company.
