Detroit and Cleveland to Florida. Following is a partial list of the many named passenger trains that Seaboard operated during the first half of the 20th century, some of which were continued by successors Seaboard Coast Line (SCL) and Amtrak. Trains originating in New York were handled by the Pennsylvania Railroad from New York to Washington; by the Richmond, Fredericksburg and Potomac Railroad from Washington to Richmond; and by Seaboard from Richmond to points south. Prior to the completion of Seaboard's Cross-Florida extension from Coleman to West Palm Beach (1925) and on to Miami (1926), the Florida East Coast Railway handled SAL trains from Jacksonville to Miami. Thereafter, Seaboard split most major southbound trains at Wildwood, just north of Coleman, with one section going to Tampa and west coast points, and the other going to Miami. Northbound, the process was reversed, with west and east coast sections joining at Wildwood to continue their journey. Heavyweight trains The term heavyweight refers to trains consisting of passenger cars with all-steel construction, considered a great improvement in safety over the all-wooden or wood-and-steel cars of the 19th century. By 1910, nearly all major railroads were replacing their wooden passenger fleets with cars of heavyweight construction. Note: The history of train names on various Seaboard routes is complex, with some being temporarily replaced or discontinued for a year or two, then brought back, perhaps on a somewhat different routing (e.g., to both coasts of Florida or to only one); the following is merely a rough guide to the names of some of the major year-round trains Seaboard offered. Consult sources listed at the end of this article for exact details. Before the Cross-Florida Extension from Coleman to West Palm Beach was completed in 1925 (and extended to Miami in 1927), Seaboard trains for cities on the Atlantic side of Florida were handled by the Florida East Coast Railway south of Jacksonville.
