Despite initial plans to return for select event weekends during the shoulder season, Ocean City’s Boardwalk trams are officially finished running for the remainder of the year following an incident last month. Service has been suspended since the evening of Aug. 20, after a tram driving south on the concrete lane near Dorchester Street struck and killed a toddler who was running back from the beach toward the Boardwalk. The identities of the people involved have not been released.
