Delmar is a town in Wicomico County, Maryland, United States. The population was 3,003 at the 2010 census. It is included in the Salisbury, Maryland-Delaware Metropolitan Statistical Area. When the population is added to “twin city” Delmar, Delaware, the town’s total population is 4,600. By comparison this is more than Pocomoke City, Maryland 4,184, Denton, Maryland 4,418, and Berlin, Maryland 4,485, but less than Fruitland, Maryland, 4,866. The Town of Delmar was founded in October 1859 with the extension of the Delaware Railroad to the southern boundary of Delaware.
The Transpeninsular Line was responsible for the founding of this unique bi-state town because the Charter of the Delaware Railroad Company permitted only the building of a railroad within the State of Delaware and the charter of the corresponding railroad company in Maryland permitted only the laying of railroad track within the State of Maryland. Thus, in 1859, the two respective railroads met and the Town of Delmar was born. The name of Delmar was derived for this railroad center from the states whose line it straddles – DELaware and MARyland. The Town of Delmar grew slowly until 1884 when the New York, Philadelphia and Norfolk Railroad Co. completed a railroad from Pocomoke City, Maryland to Cape Charles, Virginia and also established a ferry service across the Chesapeake Bay between Cape Charles and Norfolk, Virginia.
