From Tampa north to Sulphur Springs, the Clearwater Subdivision runs along the former
Tampa Northern Railroad, which was built in 1908. From Sulphur Springs west to Clearwater, it runs along the former
Tampa and Gulf Coast Railroad, which was built in 1914. Both the Tampa Northern Railroad and the Tampa and Gulf Coast Railroad were absorbed by the
Seaboard Air Line Railroad (SAL) in 1913 and 1915 respectively. From Clearwater to St. Petersburg, the line runs along the southern end of the historic
Orange Belt Railway, which was built in 1888. The Orange Belt Railway later became part of the
Plant System, which soon after became part of the
Atlantic Coast Line Railroad (ACL). '' of the
Seaboard Air Line Railroad (SAL) with shrouded steam locomotive #865 at the St. Petersburg station in 1940. From the 1910s to the 1960s, both the ACL and SAL operated long-distance passenger trains over their respective portions of what is now the Clearwater Subdivision. SAL trains ran the line between Gary and Clearwater, with stations in Oldsmar and Safety Harbor. Beyond Clearwater, SAL track continued south along the present-day
Pinellas Trail to St. Petersburg. ACL trains ran on the now-CSX Clearwater Subdivision's tracks between Clearwater and St. Petersburg. The ACL's line previously continued north from Clearwater to
Dunedin,
Tarpon Springs, and
Trilby. When
Amtrak took over rail passenger service on May 1, 1971, it operated the
Silver Meteor and
Silver Star deluxe passenger trains over the line via Tampa, providing Clearwater and St. Petersburg with daily overnight service to New York and intermediate points. Both the Atlantic Coast Line and the Seaboard Air Line networks merged on July 1, 1967, to form the
Seaboard Coast Line Railroad (SCL). In the years following the merger, the SAL track was abandoned south of Clearwater, replaced by a new crossover built in North Clearwater at milepost SY 873.0 to permit use of the former ACL line south to St. Petersburg. On November 1, 1980, the Seaboard Coast Line became part of
CSX. Regularly scheduled passenger rail service on the line ended on February 1, 1984, when Amtrak discontinued its rail services in
Pinellas County, choosing to terminate its trains at
Tampa Union Station. Substitute
Amtrak Thruway service has been provided since then between Tampa Union Station and
Pinellas Park. The old SAL passenger stations in Safety Harbor and Oldsmar were demolished in 1965 and 1967, respectively.
Recent history In March 2008, the Clearwater Subdivision's trackage in downtown St. Petersburg was pulled up, along with the South Side Spur, which ran south of Central Avenue and east of
34th Street South (part of the former Seaboard line). That right-of-way, as well as the right-of-way of several other former CSX railroad lines in the county beginning in the 1990s, was converted into a section of the
Pinellas Trail. Today, the line ends at 5th Avenue North in St. Petersburg. Though, some severed track segments remain between
I-375 and
Tropicana Field. ==See also==
