{{Manual/Introduction}}
This section aims to explain some words used in this manual, if they might be ambiguous or not obvious. Additionally, some of the notations are explained.

;DOS version:The DOS version refers to the older version of TTD that runs in DOS, or in a DOS window. Even if it runs under Windows, it is still the DOS version of TTD.

;Windows version:The Windows version is the more recent version of TTD. It is a native Windows application that uses DirectX to communicate with the graphics and sound hardware.

;Station:A station is either a station complex or a station facility, depending on the context.

;Station complex:Several station facilities connected together such that they form a single unit. A station complex can combine several different types of carriers. The name, ratings and goods waiting are always stated for the whole station complex, not for each individual facility.

;Station facility:One of the parts that make up a station complex, it can be a train station, bus or truck terminal, airport, heliport or ship docks.

;Vehicle:Any mobile unit that you can buy individually, i.e. train engines and wagons, road vehicles, aircraft and ships.

;Carrier:A vehicle or consist that is able to transport a certain type of cargo, e.g. planes can be both passenger and mail carriers.

;Engine:The powered vehicle(s) present in every consist. For trains the engine refers to only the train engine(s) without the wagons, for all others it refers to the vehicle itself.

;Consist:An operational set of vehicles that are given commands together. It refers to the entire train including engine and wagons, or the bus, truck, aircraft or ship. See also carrier.

Some additional clarifications: A road, air, or water consist is a single vehicle that functions as both engine and carrier. A rail consist is multiple vehicles including an engine and at least one carrier. Some engines are made of two vehicles and some engines are also carriers.

;Option:An option is specified on TTDPatch's command line, to either select what patches should be applied (see switch) or to otherwise control how TTDPatch runs.

;Patch:A patch is a modification of TTD's behaviour, through TTDPatch. Can be activated using a switch.

;Switch:A switch is an option that selects what patches TTDPatch should apply. It can be specified either as an option on the command line, or as an entry in the configuration file.

Definition of notations:

;&lt;angle brackets&gt;: Angle brackets are placeholders, to be replaced by the actual data of your choice. For example, the "Year" sign cheat is defined as Cht: Year &lt;number&gt;. This means that you should replace &lt;number&gt; with the number of the year, e.g. Cht: Year 2034.

;[square brackets]: Square brackets indicate an optional component. For example, the "tracks" sign cheat is defined as Cht: &lt;to&gt; [&lt;from&gt;]. This means that &lt;to&gt; is mandatory and must always be specified, but [&lt;from&gt;] is optional. As a result, both Cht: 1 and Cht: 1 2 are valid examples of the track cheat.
