Train ferry


A train ferry is a ship designed to carry railway vehicles. Typically, one level of the ship is fitted with railway tracks, and the vessel has a door at the front and/or rear to give access to the wharves. In the United States, train ferries are sometimes referred to as "car ferries", as distinguished from "auto ferries" used to transport automobiles. The wharf has a ramp, and a linkspan or "apron", balanced by weights, that connects the railway proper to the ship, allowing for the water level to rise and fall with the tides.
While railway vehicles can be and are shipped on the decks or in the holds of ordinary ships, purpose-built train ferries can be quickly loaded and unloaded by roll-on/roll-off, especially as several vehicles can be loaded or unloaded at once. A train ferry that is a barge is called a car float or rail barge.

History

An early train ferry was established as early as 1833 by the Monkland and Kirkintilloch Railway. To extend the line over the Forth and Clyde Canal in Scotland, the company began operating a wagon ferry to transport the rolling stock over the canal. In April 1836, the first railroad car ferry in the U.S., Susquehanna, entered service on the Susquehanna River between Havre de Grace and Perryville, Maryland.
The first modern train ferry was Leviathan, built in 1849. The Edinburgh, Leith and Newhaven Railway was formed in 1842 and the company wished to extend the East Coast Main Line further north to Dundee and Aberdeen. As bridge technology was not yet capable enough to provide adequate support for the crossing over the Firth of Forth, which was roughly five miles across, a different solution had to be found, primarily for the transport of goods, where efficiency was key.
The company hired the up-and-coming civil engineer Thomas Bouch who argued for a train ferry with an efficient roll-on roll-off mechanism to maximise the efficiency of the system. Custom-built ferries were to be built, with railway lines and matching harbour facilities at both ends to allow the rolling stock to easily drive on and off the boat. To compensate for the changing tides, adjustable ramps were positioned at the harbours and the gantry structure height was varied by moving it along the slipway. The wagons were loaded on and off with the use of stationary steam engines.
Although others had had similar ideas, it was Bouch who first put them into effect, and did so with an attention to detail. This led a subsequent President of the Institution of Civil Engineers to settle any dispute over priority of invention with the observation that "there was little merit in a simple conception of this kind, compared with a work practically carried out in all its details, and brought to perfection."
The company was persuaded to install this train ferry service for the transportation of goods wagons across the Firth of Forth from Burntisland in Fife to Granton. The ferry itself was built by Thomas Grainger, a partner of the firm Grainger and Miller.
The service commenced on 3 February 1850. It was called "The Floating Railway" and intended as a temporary measure until the railway could build a bridge, but this was not opened until 1890, its construction delayed in part by repercussions from the catastrophic failure of Thomas Bouch's Tay Rail Bridge.
The largest train ferry ever built is on the Trelleborg-Rostock route, built in 1998, long, wide, with six tracks plus two on an elevator to the lower deck, having a total length of track of.

Hazards

Train ferries rarely sink because of sea hazards, although they have some weaknesses linked to the very nature of transporting trains "on rail" on a ship.
These weaknesses include:
The Ann Arbor Railroad of Michigan developed a system of making cars secure that was adopted by many other lines. Screw jacks were placed on the corners of the railcar and the car was raised slightly to take its weight off of its wheels. Chains and turnbuckles were placed around the car frame and hooked onto the rails and tightened. Clamps were placed behind the wheels on the rails. Deckhands engaged in continual inspection and tightening of the gear during the crossing. This system effectively held the cars in place when the ship encountered rough weather.
Some accidents have occurred at the slip during loading, when stability can be a major problem. Train ferries often list when heavy cars are loaded onto a track on one side while the other side is empty. Normal procedure was to load half of a track on one side, all of the track on the other side, and then the rest of the original track. If this procedure was not followed, results could be disastrous. In 1909, capsized in its slip in Manistique, Michigan when a switching crew put eight cars of iron ore on its portside tracks. The crew got off without loss of life, but salvage operations were costly and time-consuming.
The Japanese train ferry, Toya Maru, sank during typhoon Marie on 26 September 1954, killing more than a thousand. Four other train ferries, Seikan maru No.11, Kitami Maru, Tokachi Maru and Hidaka Maru also sank on that day; the loss appeared to be of about 1,430 people.
At the time, Japanese train ferries did not have a rear sea-gate, because engineers believed that in-rushing water would simply flow out again quickly and would not pose a danger. However, when the frequency of waves bears the wrong relationship to the length of a ship, each wave arrives as the water from the previous wave is trying to leave, causing water to accumulate on the ship. After the accidents, all Japanese train ferries were retrofitted with rear sea-gates and weather forecast technology was greatly promoted.
The Norwegian train ferry, Skagerrak, built in 1965, sank in gale-force winds on 7 September 1966, on a journey between Kristiansand, Norway, and Hirtshals, Denmark, when the rear sea-gate was destroyed by heavy seas. One person subsequently died of injuries, and six freight cars and a number of automobiles sank to the bottom with the ship.
, United States in April 1943.
The Canadian train ferry sank on 20 April 1970, while assisting in a search and rescue operation for a sinking fishing trawler off the northeast coast of Cape Breton Island. The ferry was trying to maintain position to retrieve a body when its stern gates were overpowered by waves. It sank within 30 minutes taking several rail cars and 4 crew members, including the Captain, to the bottom of the Cabot Strait. There were 47 survivors.
Several train ferries, including,, and, have been lost on the Great Lakes. These losses, though causes remain unconfirmed, were attributed to seas boarding the unprotected stern of the ship and swamping it in a severe storm. As a result, seagates were required on all new ships and required to be retrofitted on older vessels. In addition, two wooden cross-lake railroad ferries caught fire and burned.

Examples

Argentina

Nine train ferries were used between 1907 and 1990 to cross the Paraná river and join the Buenos Aires province and the Entre Rios province, until new bridges were built over the rivers they crossed. They were Lucía Carbó, María Parera, Mercedes Lacroze . Then were added Roque Saenz Peña and Ezequiel Ramos Mejía, paddle train ferries, at Posadas.
Three other train ferries were added later: Dolores de Urquiza, Delfina Mitre and Carmen Avellaneda to cover the service in the Zárate-Ibicuy crossing. María Parera had a collision with Lucía Carbó at km. 145 of the Paraná River, and it sank in less than 15 minutes on June 30, 1926. Two of the most modern still serve as floating piers in the Zárate region, and one of the first group was sunk during a storm at the Buenos Aires port in the 1980s. The two northern paddle ferries still remain at Posadas, and one of them holds a model railway museum inside. All the eight old ferries were built by the A & J Inglis Co. Ltd., in Pointhouse, Glasgow, Scotland, for the Entre Rios Railways Co. in Argentina. The ninth ferry, Tabare, was built in Argentina by Astarsa in 1966 at Astillero Río Santiago Río Santiago Shipyard near to La Plata city. It was the largest train ferry that operated in Argentina, with a deck more than 100 meters long. Tabaré is still floating, but not operating, at the old south docks of Buenos Aires port, near the Puerto Madero zone.

Japan

In Japanese, a train ferry is called "鉄道連絡船 tetsudō renrakusen", which means literally "railway connection ship". Such ships may or may not be able to carry railcars. A ferry service that is part of a railway schedule and its fare system is called "tetsudō renrakusen".
Japan Railways linked the four main Japanese islands with train ferries before these were replaced by bridges and tunnels.
There were three ferry services that carried trains. Through operations of passenger trains using train ferries were conducted between December 1948 and 11 May 1955. The passenger services was canceled after the disasters of Toya Maru and the Shiun Maru occurred, after which the Japanese National Railways considered it dangerous to allow passengers to stay on trains aboard ship. These three lines have been replaced by tunnels and bridges.
From 1886 to 1936, train ferries sailed between Stavoren and Enkhuizen across the IJsselmeer.
From 1914 to 1983 a ferry carried freight carriages from the Rietlanden shunting area to the Amsterdam-Noord railway network, which was not connected over land to the rest of the Dutch railway network.
