Asbury Park was established before the railroad came to town. As the railroad reached the city, new communities were formed. Many new residents moved to the area to take advantage of the railroad's convenience. Today, it's one of the most popular beach resorts in New Jersey. Its proximity to the Atlantic City made it a major summer destination. After the Civil War, Long Branch became a premier beach resort.
