DELRAY BEACH, Fla. – Four teenagers have been charged with starting a massive fire Tuesday at a vacant train station. Delray Beach Fire Rescue responded to the structure fire shortly after 10:15 a.m. when a 911 caller reported seeing heavy smoke coming from the train station. The caller also described four young males running from the train station toward Atlantic Avenue. The train depot was constructed in 1927 and was used as train station until 1991. It was added to the United States National Register of Historic Places in 1986, becoming one of six Delray Beach historic sites on the register.
