Sparks is an unincorporated community that is located in Baltimore County, Maryland, USA. Approximately 3,000 (5,094 according to 2010 census) people self-identify as living in the Sparks area. Glencoe, MD is a smaller community that is largely surrounded by Sparks and the area is sometimes collectively known as "Sparks Glencoe, Maryland."
In 1835, the Baltimore and Susquehanna Railroad constructed a track through Baltimore County which included a siding and switch near a large tract of land owned by the Sparks family. Railroad officials gave the name Sparks to the switch, and soon area residents began to refer to the location as "Sparks' Switch." Abraham Lincoln's body was carried through Sparks on the Baltimore and Susquehanna Railroad from Washington, D.C. on its way to burial in Illinois following his assassination in 1865. For a number of years a creamery was operated for farmers who brought their milk in daily to be separated. (The stone structure which once housed the creamery can be seen today.) The cream was shipped to Baltimore while the skim milk was used by the farmers on their farms. With the passage of time, Sparks' Switch came to be known simply as "Sparks." In 1888, the area had grown to a point where "a substantial foot bridge 6 feet in width" had to be built across the Gunpowder River. Beginning in 1889, a combination passenger and freight station was operated by the Northern Central Railway (NCR) along the right-of-way and line that had previously been known as the Baltimore and Susquehanna Railroad. A passenger and freight stop along the North Central Railroad was named Sparks Station. Railroad operations through Sparks ceased in 1972, as a direct result of major damage to the tracks and rail bed that occurred during flooding that followed Hurricane Agnes.
