A railroad car float or rail barge is a specialised form of lighter[1] with railway tracks mounted on its deck used to move rolling stock across water obstacles, or to locations they could not otherwise go. An unpowered barge, it is towed by a tugboat or pushed by a towboat.

This is distinguished from a train ferry, which is self-powered.

Historical operationsEdit

U.S. East CoastEdit

During the Civil War, Union general Herman Haupt, a civil engineer, used huge barges fitted with tracks to enable military trains to cross the Rappahannock River in support of the Army of the Potomac.[2]

Beginning in the 1830s, the Baltimore and Ohio Railroad (B&O) operated a car float across the Potomac River, just south of Washington, D.C., between Shepherds Landing on the east shore, and Alexandria, Virginia on the west. The ferry operation ended in 1906.[3] The B&O operated a car float across the Baltimore Inner Harbor until the mid-1890s. It connected trains from Philadelphia to Washington, D.C. and points to the west. The operation ended after the opening of the Baltimore Belt Line in 1895.[3]

The Port of New York and New Jersey had many car float operations, which lost ground to the post-World War II expansion of trucking, but held out until the rise of containerization in the 1970s.[4]

These car floats operated between the Class 1 railroads terminals on the west bank of Hudson River in Hudson County, New Jersey and the numerous online and offline terminals located in Brooklyn, Queens, Staten Island, the Bronx, and Manhattan.[5][6] Class 1 railroads in the New York Harbor area providing car float services were:

As well as the offline terminal railroads:

Car float service was also provided to many pier stations and waterfront warehouse facilities (that did not engage in car floating service directly) by the above-mentioned railroads.

At their peak, the railroads had 3,400 employees operating small fleets totalling 323 car floats, plus 1,094 other barges, towed by 150 tugboats between New Jersey and New York City.

Abandoned float bridges are preserved as part of this history at:

Several other abandoned but unrestored float bridges exist in other locations around New York Harbor. A complete list is available at Surviving Float Bridges of New York Harbor

Freight cars do not run in the East River Tunnels nor the North River Tunnels (under the Hudson River), in part due to inadequate tunnel clearances of the New York Tunnel Extension.

The Bay Coast Railroad formerly operated a 2-barge car float connecting Virginia's Eastern Shore with the city of Norfolk, Virginia across the Chesapeake Bay.

U.S. MidwestEdit

Between 1912–1936, the Erie Railroad operated a car float service on the Chicago River in Chicago, Illinois.[34]

U.S. West CoastEdit


Existing operationsEdit


The Alaska Railroad provides the Alaska Rail Marine rail barge service from downtown Seattle to Whittier on the central Alaskan mainland.[37]', CN Rail provided the Aquatrain rail barge service from Prince Rupert, British Columbia to Whittier.[38] Service ended in April 2021.[39]

New York / New JerseyEdit

The car float docks at Bay Ridge, Brooklyn, New York.

The only remaining car float service in operation in the Port of New York and New Jersey is operated by New York New Jersey Rail. This company, operated by the bi-state government agency Port Authority of New York & New Jersey is the successor to the New York Cross Harbor Railroad. Car float service operates between 65th Street / Bay Ridge Yard in Brooklyn and Greenville Yard in Jersey City, New Jersey.[40]
