Delmar, Maryland

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 Delmar, Delaware, the town’s total population is 4,600.

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. These new developments immediately made the Delmarva Peninsula an important link between the north and south. The Town of Delmar, being the midway town of the Delmarva Peninsula and already a railroad terminal, was the point for trains to change crews and locomotives and also a center for maintenance of the rolling equipment. As a result of these developments, a tremendous influx of experienced railroad men into the community and considerable extra employment was furnished for local townspeople. During this accelerated rapid growth period, Delmar became a “boom town”. New dwelling units sprang up all over town and new businesses were established to meet the demands of its growing population. By 1889, the population of the Town of Delmar had increased to 680 and was still growing.
