Gadgetbahn is a neologism that refers to a public transport concept or implementation that is touted by its developers and supporters as futuristic or innovative, but in practice is less feasible or reliable, and more expensive than traditional modes such as buses, trams and trains. It is a portmanteau of the English word "gadget" and the German word Bahn, meaning "railway". [2] [3]

The term originated in the 21st century, [4] [5] mainly used within the online public transport sphere on Twitter and YouTube. [6] [ better source needed ] However, such systems existed even before the term was coined. See individual articles for systems for details.

Light rail is a form of passenger urban rail transit that uses rolling stock derived from tram technology while also having some features from heavy rapid transit.
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road and rail technology. The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, flanged steel wheels running on rail tracks provide guidance through switches and act as backup if tyres fail. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros.
An automated guideway transit (AGT) or automated fixed-guideway transit or automatic guideway transit system is a type of fixed guideway transit infrastructure with a riding or suspension track that supports and physically guides one or more driverless vehicles along its length. The vehicles are often rubber tired or steel wheeled, but other traction systems including air cushion, suspended monorail and maglev have been implemented. The guideway provides both physical support, like a road, as well as the guidance. An automated line can be cheaper to run than a conventional line, due to the shorter trains and stations.
Guided buses are buses capable of being steered by external means, usually on a dedicated track or roll way that excludes other traffic, permitting the maintenance of schedules even during rush hours. Unlike railbuses, trolleybuses or rubber-tyred trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes.
Urban rail transit is a wide term for various types of local rail systems providing passenger service within and around urban or suburban areas. The set of urban rail systems can be roughly subdivided into the following categories, which sometimes overlap because some systems or lines have aspects of multiple types.
Various terms are used for passenger railway lines and equipment; the usage of these terms differs substantially between areas:
Public transport in Istanbul comprises a bus network, various rail systems, funiculars, and maritime services to serve the more than 15 million inhabitants of the city spread over an area of 5,712 km2.
A dual-mode vehicle (DMV) is a vehicle that can operate on conventional road surfaces as well as a railway track or a dedicated track known as a guideway. The development of these vehicles started together with personal rapid transport systems in the 1950s or even earlier.
Guided Light Transit was the name of guided bus technology and associated infrastructure manufactured by Bombardier Transportation. Two GLT prototypes were designed and tested from 1987 onwards by BN in the region of Rochefort in Belgium. It was eventully installed in two French cities: Nancy and Caen. The Caen system was closed in 2017 and replaced by conventional trams, while the Nancy system was closed in March 2023 and is to be replaced by trolleybuses.
Translohr is a rubber-tyred tramway system, originally developed by Lohr Industrie of France and now run by a consortium of Alstom Transport and Fonds stratégique d'investissement (FSI) as newTL, which took over from Lohr in 2012. It is used in Paris and Clermont-Ferrand, France; Medellín, Colombia; and Venice-Mestre and Padua in Italy. In June 2012, Alstom Group and the Strategic Investment Fund acquired Translohr for €35 million.
The Caen guided light transit or Caen TVR, locally known as "the Tram", was an electrically powered guided bus system in Caen, France, which used Bombardier Guided Light Transit technology.
A medium-capacity system (MCS), also known as light rapid transit or light metro, is a rail transport system with a capacity greater than light rail, but less than typical heavy-rail rapid transit. MCS trains are usually 1 to 4 cars. Most medium-capacity rail systems are automated or use light-rail type vehicles.
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are railways, usually electric, that unlike buses or trams operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles.
A rubber-tyred tram is a development of the guided bus in which a vehicle is guided by a fixed rail in the road surface and draws current from overhead electric wires.
Transport in Shanghai is provided by an extensive network of modes including metro, cycling, bus and taxis, as well as an expansive network of roadways, and airports. Shanghai has invested heavily in public transportation before and after the 2010 World Expo, including the construction of the Hongqiao transportation hub of high-speed rail, air, metro and bus routes.
Transport in Zagreb, the capital of Croatia, relies on a combination of city-managed mass transit and individual transportation. Mass transit is composed of 19 inner-city tram lines and 120 bus routes, both managed entirely by Zagrebački električni tramvaj, commonly abbreviated to ZET. Croatian Railways manages the parallel Zagreb Commuter Rail system. The city is served by the Franjo Tuđman Airport, which carries more than 3,300,000 passengers per year. Zagreb Airport is connected to the Zagreb Bus Station via Pleso Prijevoz shuttle and to Eugen Kvaternik Square via bus line 290 which connects the aforementioned square with the satellite city of Velika Gorica via the Airport.
Urban rail transit in India plays an important role in intracity transportation in the major cities which are highly populated. It consists of Regional Rapid Transit System, suburban rail, monorail, and tram systems.
Autonomous Rail Rapid Transit (ART) is a lidar guided bi-articulated bus system for urban passenger transport. Developed and manufactured by CRRC through CRRC Zhuzhou Institute Co Ltd, it was unveiled in Zhuzhou in the Hunan province on June 2, 2017. ART is specifically referred to as a train or rapid transit as Digital-rail Rapid Transit and electric road by its manufacturer, however the public describes it as a bus or trolleybus and bus rapid transit. Its exterior is composed of individual fixed sections joined by articulated gangways, resembling a rubber-tyred tram and translohr.
