Articulated trams, were invented and first used by the Boston Elevated Railway in 1912–13. [2] This was instead of using trailers or multiple units, which had been attempted in the early 1900s. The articulated design allows passengers (and fare inspectors) to move the entire length of the vehicle, whether stopped or in motion.
Articulated passenger cars are becoming increasingly common in Europe and the US. The passageways between the car elements are permanently attached. There is a safety benefit claimed that if the train derails, it is less likely to jackknife and modern construction techniques prevent telescoping. Articulated cars are not, however, a new idea.

To fill the need for such vehicles, a specialized design bureau was established with the task of developing articulated tracked vehicles. Also a military vehicle able to operate on USSR northern borders was deemed necessary. In February 1971 the first two ATVs, designated DT-LP and DT-L, were produced for the State trials.
Tracked articulated vehicles typically steer by actuating the linkage connecting the cars of an articulated tracked vehicle. This linkage, called the train joint, uses hydraulic actuators [ 1 ] to position the front vehicle in an opposing direction to the rear one, and curves the direction of travel this way. [ 2 ]
The Landmaster is a unique 12-wheeled amphibious articulated vehicle constructed by Dean Jeffries at Jeffries Automotive in Universal City, California, for the 1977 science fiction film Damnation Alley (itself based on a novel by Roger Zelazny).
A less common variant of the articulated bus is the bi-articulated bus, where the vehicle has two trailer sections rather than one. Such vehicles have a capacity of around 200 people, and a length of about 25 m (82 ft); as such, they are used almost exclusively on high-capacity, high-frequency arterial routes and on bus rapid transit services.
The Gama Goat was a six-wheel drive semi-amphibious off-road vehicle originally developed for use by the US military in the Vietnam War.The Goat uses an articulated chassis, so that from distance it appears to be a four-wheel drive vehicle pulling a two-wheel trailer, but it is a single six-wheel vehicle with a four-wheel steering arrangement with the front and rear wheels turning in opposite ...
