Seatrain Lines, the operating name for the Over-Seas Shipping Company, began
intermodal container shipping by using entire loaded rail cars between ports in the United States and
Havana, Cuba, with the first shipment in December 1928 aboard a specially designed ship,
Seatrain. This original ship, built at
Swan Hunter & Wigham Richardson,
Newcastle and later renamed
Seatrain New Orleans, was capable of carrying 95 fully loaded rail cars. The loading system consisted of a cradle that fit into a depression on the
pier. Railway lines running on the pier continued onto the cradle and past it. Rail cars were rolled onto the cradle one at a time, and then lifted by a large overhead crane. The system was very similar to modern
intermodal container loading systems, with the exception that it lifted the load from the bottom rather than the top. The crane rolled the cradle over a large hatch slightly longer than the cradle and as wide as the ship. The cradle could be lowered to match one of four internal decks (including the top surface) and moved side-to-side to match one of four parallel sets of rails on the decks. Once positioned, the car was pulled off by steam driven
winches. During the voyage of the ship the cars were secured by
chocking the wheels and using
jacks and
turnbuckles at each corner of the car.
boxcar from the
Seatrain Louisiana. The company built two larger specialized ships in 1932,
Seatrain New York and
Seatrain Havana with greater rail car capacity. This service was the forerunner of modern container shipping inaugurated in the late 1950s by other shipping companies. Seatrain was initially located in
Hoboken,
New Jersey, and owned the
Hoboken Manufacturers Railroad that connected its facility to other railroads. In 1939 two more ships were under construction at
Sun Shipbuilding and Dry Dock Company, Chester, Pennsylvania, with hulls 191 and 192 becoming and respectively. In 1944, the five vessels were noted as being unique in the commercial shipping world as described in a decision by the
Comptroller General of the United States concerning issues in setting wartime charter rates. The decision noted "these were the only vessels of this type in existence, there was no market for such vessels" and that the "inherent character and design of these vessels which reduces the cost of loading and discharging cargo to a nominal amount per ton, and which by the use of mechanical devices, reduces the time for discharging and reloading to a few hours as compared to a few days" for ordinary ships. Those unique characteristics, though making setting a "market value" difficult, made the ships of particular utility for wartime transport of large, assembled vehicles and machines. The original 1928 shipment aboard
Seatrain caused a labor issue that foretold similar issues later with
container ships when Cuban stevedores demanded that they not only unload the rail cars from the ship but unload and repack the rail car contents before turning the cars over to Cuban railways. Seatrain reached agreement with labor but the issue was a precursor to similar labor problems with containers in other ports. In 1951 Seatrain Lines returned to Sun Shipbuilding for two additional railcar carriers, the
Seatrain Georgia and
Seatrain Louisiana. That year Seatrain also ceased operations to and from Cuba, and renamed its ship
Seatrain Havana to
Seatrain Savannah to reflect the suspension of service. In 1953 Seatrain sold its operating authority to trade between the US and Cuba to the
West India Fruit and Steamship Company, along with its first ship, the
Seatrain New Orleans, which was renamed
Sea Level. In 1958, Seatrain Lines introduced its Seamobile intermodal cargo container service, carrying the containers on its railcar-carrying ships between Seatrain's Edgewater terminal on the New Jersey side of New York harbor, and Texas City (Houston). In 1959,
Sea-Land Service founder
Malcom McLean, a pioneer and leader in
intermodal marine-rail-highway containerization, attempted to buy the competing Seatrain Lines, but his offer was rejected. In 1963 Seatrain tried to expand its ship/rail operations with a New York to
Puerto Rico run, but this service was severely hampered by the inadequacies of
rail transport in Puerto Rico. In addition, Sea-Land Service had introduced containerized service to Puerto Rico in 1958. To compete, Seatrain Lines discontinued the transport of rail cars to Puerto Rico and utilized containers instead. Transeastern Associates, a firm created in the early 1950s by
Joseph Kahn and
Howard Pack, bought Seatrain Lines in 1965 for $8.5 million. At the time of their purchase, Seatrain operated between New York and ports in
Savannah, Georgia,
Texas City, Texas,
New Orleans and Puerto Rico. Transeastern and its subsidiary Hudson Waterways Corp. were folded into Seatrain in September 1966. At the time, Seatrain had lost more than $500,000 in a four-month period before the merger, while Transeastern's fleet had netted nearly $7 million in a ten-month period. In 1966, Seatrain began a program to reinvent itself by replacing its aging and obsolete railcar-carrying ships with a fleet of multi-purpose heavy sea-lift ships and cellular
container ships. All would be heavily rebuilt from surplus
World War II era type
T2 tankers and
C4 transports obtained by Hudson Waterways through the
Maritime Administration (MARAD) ship exchange program. The multi-purpose ships were mainly intended for charter to the
Military Sea Transportation Service (MSTS) in support of overseas U.S. military operations, particularly the war in
Vietnam, while the container ships would allow Seatrain to containerize its commercial cargo operations.
Seatrain Puerto Rico was the first of the heavy sea-lift ships completed in 1966, followed by
Seatrain Carolina,
Seatrain Florida,
Seatrain Maryland,
Seatrain Maine,
Seatrain Washington and
Seatrain Ohio in 1967. The ships were equipped with two cranes for self-loading and unloading and could carry general bulk and palletized cargo,
intermodal containers, and vehicles. The lower and main decks also had embedded rails to allow for carrying railcars, although there is no evidence that any of the ships were ever employed as railcar carriers
per se, except for transporting some narrow-gauge rolling stock to Vietnam, in which case the standard-gauge rails could not be used. Elevated spar decks provided additional carrying space for vehicles, aircraft and containers.
Seatrain San Juan was the first of the container ships to be completed in 1967, followed by
Seatrain Delaware. The container ships were employed in coastwise U.S. East Coast and Puerto Rico service. In 1969, the
Transchamplain,
Transontario,
Transoneida,
Transhawaii,
Transidaho,
Transindiana and
Transoregon were added, allowing Seatrain to expand domestic container service to the U.S. West Coast and Hawaii, and to begin transatlantic service between the U.S. East Coast and the U.K and Northern Europe. In 1971, Seatrain placed two new high-speed
gas turbine-powered container ships in service on its transatlantic route, the German-built
Euroliner and
Eurofreighter. They were joined in 1972 by the
Asialiner and
Asiafreighter in anticipation of expanding its transpacific service. On August 17 of that same year, Seatrain, in partnership with the
Penn Central and
Atchison, Topeka and Santa Fe railroads, also established a pioneering coast-to-coast land bridge rail container service between its U.S. East and West coast terminals, cutting up to 10 days off the transit time between Europe and the U.S. West coast and Asia. In 1974,
Matson Navigation Company took over Seatrain's West Coast–Hawaii service, leasing the
Transoneida,
Transchamplain and
Transontario to handle the traffic. In 1975,
Navieras de Puerto Rico, also known as the
Puerto Rico Maritime Shipping Authority, took over Seatrain's operations to and in Puerto Rico, along with the ships
Transhawaii,
Transidaho and
Transoregon, which became Navieras'
Aguadilla,
Carolina, and
Mayaguez (often confused with the
Sea-Land Service ship of the same name involved in the
Mayaguez incident). These two changes left Seatrain to concentrate on its international transatlantic and transpacific operations and replace its original converted container ships, mainly with a fleet of chartered ships, plus the new-builds
Seatrain Independence,
Seatrain Bennington,
Seatrain Chesapeake,
Seatrain Oriskany,
Seatrain Saratoga, and
Seatrain Yorktown. Struggling to remain solvent in the wake of its disastrous excursion into shipbuilding, a dramatic increase in fuel costs following the
Organization of the Petroleum Exporting Countries (OPEC) price increases of the mid-1970s, and the rapid replacement and expansion of its fleet in the late 1970s, and a deepening
business downturn, in 1980 Seatrain began divesting its chartered tonnage and cut its rates in the North Atlantic lane to attract more traffic. This set off a rate war which only added to the losses. In August Seatrain sold its transatlantic operations and the ships
Seatrain Bennington and
Seatrain Saratoga to
Trans Freight Lines, and then concentrated on restructuring its Pacific operations under the name
Seatrain Pacific Service, or
Seapac. == Bankruptcy ==
