Not only are there tracks there, but they are used too. The Cape May Seashore Lines exursion train uses the southern stretch of the route. These trains don't run all the way to Atlantic City, though. The tracks between AC and Cape May Courthouse probably need to be restored for full service between Philly and Cape May.

Such a service would be good not only for people going to Cape May, but for those who want to run between Cape May and Atlantic City during their vacations.

Such a service would also be good for people who do need to drive to the Shore, because there'd be fewer cars to fight with on the way down.
