''Transport Tycoon'' is a pair of [[SpaceManagementGame business management]] [[SimulationGame simulation games]] created by legendary Scottish game developer [[http://www.chrissawyergames.com/ Chris Sawyer]] (of ''RollerCoasterTycoon'' and MicroProse fame). The apparent object of the games is to end up with a monopoly of transport services for a usually randomly generated map. Transport is provided in all four major modes; air, rail, bus, and water, though the most profit tends to come from rail and then air.

The two games in the series are ''Transport Tycoon'' (released in 1994 and now referred to as Original) and ''Transport Tycoon Deluxe'' (released in 1995).

''Transport Tycoon Deluxe'' is an [[UpdatedRerelease updated version]]. It contains numerous bugfixes and gameplay improvements, including new transport modes and UI. The primary difference between the games is how signals operate. The original Transport Tycoon allows only bi-directional signals, which allow trains to pass in either direction. The Deluxe version introduced uni-directional signals, that only allow a train to pass in a single direction. The FanRemake ''Open TTD'' is derived from ''Transport Tycoon Deluxe''.

The game was superseded officially by its 2004 SpiritualSuccessor, ''{{Locomotion}}''. The free software fan game, ''Open TTD'', was established around the same time and is still going strong. There is also a FanSequel of sorts, called ''Simutrans'', but it's an indie game only InspiredBy and not related or legally connected to the ''Transport Tycoon'' series.

----
!!The ''TransportTycoon'' series contains examples of:
* AcceptableBreakFromReality: Even the most sprawling metropolises will only house about 30,000 people.
** The effects of events like WorldWarTwo or the 1970s oil crisis on the economy are completely absent.
** Helicopters, which are quite useful for delivering mail and passengers in big cities, effectively cease to exist after 2020.
* AdamSmithHatesYourGuts: The prices eventually rise so high that a piece of road costs more than a skyscraper in real life.
* AfterActionReport: Some fans of the series frequently compile these to describe how they built up their company and the country's transportation infrastructure during their playthrough. Pre-made scenario maps are especially popular for AAR recaps.
* AnEntrepreneurIsYou: The series is considered one of the classics of the "tycoon" genre of business sims.
* ArtificialStupidity: The stupid things the AI tries to pass as traffic routes [[http://www.nylon.net/ttd/stupid/index.htm has to be seen]] to be believed. The AI is less insane in ''Open TTD'', though it's still a pushover.
* PhysicsGoof: Trains can go around extremely tight corners at 300mph, but immediately slow down to a crawl when encountering a tiny hill. Only the [=OpenTTD=] implementation finally added a (more) realistic acceleration model.
* AwesomeButImpractical: Aircraft. There is no doubt that they are [[CoolPlane awesomely cool]] and fast, but their low cargo capacity and need for expensive airport infrastructure makes them, well...[[ExactlyWhatItSaysOnTheTin impractical]].
** Averted in OpenTTD, where vast maps (2048x2048) can make Planes a game-breaking tool.
* {{Bizarrchitecture}}: Some of the [[TwentyMinutesintotheFuture post-1990s]] futuristic buildings and vehicles are really odd looking.
* BoringButPractical: Road vehicles. They don't have the allure of trains or the inherent coolness of aircraft, but they can use existing city roads (and roads laid by your competitors!) and are much less affected by gradients. [=OpenTTD=] has a large number of add-on packs that increase their usability, especially since ''VideoGame/TrafficGiant''[=/=]''Simutrans''-style individual destinations for passengers and cargo have been introduced which for example make town buses as feeder lines to a train station or an airport possible.
* TheComputerIsACheatingBastard: On higher difficulties, rival companies enjoy automatically high ratings.
** NotPlayingFairWithResources: AI can completely destroy their environments around towns with no ill effect; the local authority will hate you and you will hate it if you bulldoze one tree. Justified, in that the AI as designed couldn't possibly compete with human players without this kind of handicap.
** Absent in OpenTTD, AIs now are able to survive without cheating.
* [[ColourCodedArmies Colour Coded Companies]]: All companies have a single, associated colour. ''{{Locomotion}}'' and ''Open TTD'' allow you to violate this, letting you choose different colours for different vehicles (e. g. different colours for steam, diesel, and electric locomotives).
* CoolPlane: Several, from early propeller driven craft to the supersonic [[strike:Concorde]] ''[[LawyerFriendlyCameo Yate Haugan]]'' (i.e. the Concorde).
* CoolTrain: Of course. Classic steam engines, diesel and electric locomotives of various sizes. And, from the 1990s onward, monorails and even maglevs !
* CorruptCorporateExecutive: Acting like one is optional for the player. You can [[ScrewTheRulesIHaveMoney bribe local governments]] for [[{{Nepotism}} transport monopolies]], [[PropagandaMachine city-wide advertising campaigns]], and [[VehicularSabotage "essential" reconstruction of a town's roads (in a competitor's town, of course)]].
* CrapsackWorld: Intercity transport is controlled solely by [[CorruptCorporateExecutive private companies]] who tear up the landscape, dominate small towns with massive transport complexes, and compete with each other to the point of bribery and [[SuicideMission sabotage]]. Also, [[ArsonMurderAndJaywalking there are UFOs]].
** Gets doubly crapsack when you realise who the [[{{X-COM}} UFO's belong to...]]
* CreatorProvincialism: Before the name change for legal reasons that came in ''Deluxe'', all vehicles in the game sported not only the likeness of their RealLife counterparts, but also their names. Most of these were of British manufacture, representative of British vehicle evolution over the 20th century. This is played particularly straight with nearly all locomotives, as well as virtually all antique trucks (e.g. Bedford, Scamell, etc.) and buses (e.g. the [[http://upload.wikimedia.org/wikipedia/commons/thumb/b/b9/1929-AEC-Regal-UU6646.jpg/1024px-1929-AEC-Regal-UU6646.jpg AEC Regal]]). However, Sawyer subverted and averted this approach in other parts of the purchase rosters : Only a few aircraft come from UK companies (e.g. the [[http://en.wikipedia.org/wiki/Vickers_Viscount Vickers Viscount]], [[http://en.wikipedia.org/wiki/BAC_1-11 BAC 1-11]], [[http://en.wikipedia.org/wiki/BAe_146 BAe 146]], partly the [[http://en.wikipedia.org/wiki/Concorde Concorde]]), with your first available aircraft being a ''[[ItMakesSenseInContext German]]'' [[http://en.wikipedia.org/wiki/Ju_52 Junkers Ju 52]]. Most later 20th century road vehicles are of European (Renault, Volvo, Peugeot) and American brands or marques (Ford), while keeping some British-made buses around (e.g. the [[http://en.wikipedia.org/wiki/Leyland_Leopard Leyland Leopard]]). The vast majority of the ships are actually generic, not meant to represent any specific RealLife models. The only exception to the this would be the unnamed model of hovercraft, which is clearly modelled on the classic British [[http://en.wikipedia.org/wiki/SR.N4 Saunders-Roe SR.N4 "Mountbatten class"]].
* CurbStompBattle: If an AI competitor is using road vehicles, it's possible to set up a rail line across the road and order a locomotive to "dispose" of AI vehicles. This leaves your reputation and the locomotive completely unharmed.
* DifficultButAwesome: Trains. The most complicated transport method to set up initially (especially if you're trying to network all your lines together), but overall the most efficient way to ship non-passenger goods (Planes are best for passengers).
* DownloadableContent: ''[=OpenTTD=]'' has this in ''spades,'' specifically with the "Check Online Content" option. There are ''hundreds'' of [=NewGRFs=], scenarios, [=AIs=], and game scripts available.
* EasyLogistics: Averted in that vehicles need to be maintained, otherwise they break down. Played straight with passenger and cargo; they will go wherever you ship them.
* GameMod / FanRemake : ''[=OpenTTD=]''.
** ''[=TTDPatch=]'' is exactly this: a GameMod for ''Transport Tycoon Deluxe'' which alters the executed binary code at runtime while leaving the original executables intact.
** ''[=OpenTTD=]'' itself has got loads of patches and several ready-to-compile or pre-compiled patch packs.
* GenteelInterbellumSetting: The original starts in 1930. ''Deluxe'' has [[TheFifties 1950]] as the earliest date. SpiritualSuccessor ''{{Locomotion}}'' starts in 1900. ''[=OpenTTD=]'' can start even earlier, given the right [=NewGRFs=].
** By extension, the game features TheEdwardianEra, TheRoaringTwenties, TheFifties, TheSixties, TheSeventies, TheEighties, TheNineties, and TurnOfTheMillennium. In the SpiritualSuccessor ''{{Locomotion}}'', which starts in 1900, each time period gets era-appropriate music, Ragtime for 1900-1920, jazz and blues up to the 1950s, and then various forms of rock and roll and so on up through the 1990s.
* GroundhogDayLoop: After December 31, 2060, the date loops back to January 1, 2060, rather than proceeding to 2061. A GameBreakingBug if you have vehicles scheduled for maintenance in 2061...
* KarmaMeter: Crash accidents make your company rating go down. This can be used cleverly to cause trouble for your opposition, however.
* LawyerFriendlyCameo / CaptainErsatz : All vehicles from the original 1994 UK installment were real ones from the various eras of the 20th century and all of them used their RealLife names. To avoid potential lawsuits, every vehicle in the US release, and subsequently the ''Deluxe'' version (and by extension, ''Open TTD'') was renamed. For example, a Vickers Viscount becomes a "Coleman Count", the TGV Réseau becomes the "TIM", an Eurostar becomes an "Asiastar", a Boeing 747 is a "Darwin 300", the Lockheed Tristar is a "Guru Galaxy", all planes of the Airbus brand are called "Airtaxi", and the Concorde is referred to as a "[[InherentlyFunnyWords Yate]] [[MemeticMutation Haugan]]".
** Several of these vehicles new names are {{Shout Out}}s to the QA testers' last names, including Bakewell, Luckett, Sampson, Kirby, Witcombe, Uhl, and Dinger.
* MadeOfExplodium: When two vehicles or convoys collide (except the train in a road/train collision), the vehicles will explode into a fireball. This occurs even if the vehicles aren't carrying flammables of any type, such as an electric passenger train.
* LevelAte / ToyTime: The "Toyland" climate.
* ObstructiveBureaucrat: City and town councils can become this, for better or for worse. Especially if they don't know your company well yet and you start massively altering their surroundings and tearing down older buildings - they'll simply ban you from constructing any of your company's structures on their territory, until you regain your reputation (which can often take years).
** Conversely, be on good enough terms with a Town Council, and the player can encourage [[CorruptBureaucrat a Council-sponsored]] reconstruction of the town's roads, blocking any [=AI=]-controlled road traffic for months.
* PlotDrivenBreakdown: Every single time [[ShoutOut a small UFO]] flies above a bus, they ''both breakdown at the exact same time'' and UFO crashes [[ActionBomb exactly onto the bus]].
* PublicDomainSoundtrack: SpiritualSuccessor ''{{Locomotion}}'' uses Scott Joplin Ragtime pieces for the 1900-1920 era of the game. Averted after 1920, and also averted in ''Transport Tycoon''.
** ''[=OpenTTD=]'' has got an entire Scott Joplin soundtrack among its DownloadableContent.
* UnitsNotToScale: Ships are not much bigger than train cars. In reality, cargo ships carry hundreds of containers which are as big as train cars. Additionally, facilities such as train stations and railyards can be as big as or bigger than the cities they serve.
* ShoutOut / EasterEgg : Every now and then, an ''{{X-COM}}'' fighter jet or UFO will appear and fly around the map.
* SuicideMission: As detailed below, this is a [[CrapsackWorld perfectly reasonable]] way of dealing with competitors.
* VideoGameCaringPotential: Want to try and nurse mainline steam traction into the 21st century ? Now's your chance.
* VideoGameCrueltyPotential:
** It's possible to cause the deaths of thousands of people in one go by judicious use of the "Ignore signal" button.
** It takes a little time to set up, but if you have created cities directly at sea level, only protected by a dike, and then delete the dike, the city will be overrun by the water and destroyed.
*** There is a map in Transport Tycoon Deluxe called "Damn!" where the ''entire map'' is at sea level and protected by a dike.
** You can [[VehicularSabotage take revenge]] on the [[TheComputerIsACheatingBastard computer-favoured]] [[ArtificialStupidity AI opponents' badly built railways]] by building a railway depot at the end of their stations, buying a cheap locomotive and [[SuicideMission sending it running into the opponent's station]]. His train eventually enters the station, your locomotive charges at his train kamikaze-style ''[[StuffBlowingUp and...]]''
* VideoGameTime: A day passes every few seconds, so trains take weeks to travel from one town to another. Because of this, we have the oddity that passengers will pay through the the nose for the privilege of travelling a couple of miles in "only" ten days.
* TheWikiRule: [[http://www.tt-wiki.net/wiki/Main_Page Transport Tycoon Wiki]], [[http://wiki.openttd.org/Main_Page OpenTTD Wiki]] and even more specialized wikis.
