(carriage, car), with a driver's cab at one or both ends. Some railway companies, such as the Great Western, termed such vehicles " railmotors" (or "rail motors"). Self-propelled passenger vehicles also capable of hauling a train are, in technical rail usage, more usually called " rail motor coaches" or "motor cars" (not to be confused with the motor cars, otherwise known as automobiles, that operate on roads). The term is sometimes also used as an alternative name for the small types of multiple unit which consist of more than one coach. That is the general usage nowadays in

when referring to any diesel multiple unit (DMU), or in some cases electric multiple unit (EMU). In North America the term "railcar" has a much broader sense and can be used (as an abbreviated form of "railroad car") to refer to any item of hauled rolling-stock, whether passenger coaches or goods wagons (freight cars). Self-powered railcars were once common in North America; see Doodlebug (rail car). In its simplest form, a "railcar" may also be little more than a motorized railway handcar or draisine.

Railcars are economic to run for light passenger loads because of their small size, and in many countries are often used to run passenger services on minor railway lines, such as rural railway lines where passenger traffic is sparse, and where the use of a longer train would not be

Petrol

In 1904 the Automotor Journal reported that one railway after another had been realising that motor coaches could be used to handle light traffic on their less important lines. The North-Eastern railways had been experimenting “for some time” in this direction, and Wolseley provided them with a flat-four engine capable of up to for this purpose. The engine drove a main dynamo to power two electric drive motors, and a smaller dynamo to charge accumulators to power the interior lighting and allow electric starting of the engine. The controls for the dynamo allowed the coach to be driven from either end. For further details see 1903 Petrol Electric Autocar. Another early railcar in the UK was designed by James Sidney Drewry and made by the

Battery-electric

Experiments with battery-electric railcars were conducted from around 1890 in Belgium, France, Germany and Italy.

New-generation DMU and EMU railcars

A new breed of modern lightweight aerodynamically designed diesel or electric regional railcars that can operate as single vehicles or in trains (or, in “multiple units”) are becoming very popular in Europe and Japan, replacing the first-generation railbuses and second-generation DMU railcars, usually running on lesser-used main-line railways and in some cases in exclusive lanes in urban areas. Like many high-end DMUs, these vehicles are made of two or three connected units that are semi-permanently coupled as “married pairs or triplets” and operate as a single unit. Passengers may walk between the married pair units without having to open or pass through doors. Unit capacities range from 70 to over 300 seated passengers. The equipment is highly customisable with a wide variety of engine, transmission, coupler systems, and car lengths.


Institutional/regulatory Issues

Contrary to other parts of the world, in the United States these vehicles generally do not comply with
