Ok, so we’ve been helping out various industries in the OpenTTD world for a while now, but we haven’t addressed an important question yet – what are the industries and how do they work? As we have seen in brief already, industries are entities that produce specific cargo and/or services. There are actually three types of industries in OpenTTD: primary, secondary and tertiary. Primary industries, such as Coal or Iron Ore Mines, provide resources without requiring any type of resource input, and these resources then need to be transported to a secondary industry. The growth of the output of primary industries actually depends upon the percentage of cargo transported away from them to these secondary industries, making our job extremely important for growth – the more we transport, the faster the primary industry grows in the long term on average. Meanwhile, sometimes secondary industries will provide a resource that will either need to be transported to Towns, such as goods or food, or to a tertiary industry. However, remember that our company only transports cargo on behalf of the manufacturers, and any profits we make are purely from the transportation fees we charge, not from the sale of the cargo – this is a game about transportation, after all.
Now, we have already seen what the Industry window for an individual industry looks like, such as the Coal Mine shown to the right, but I haven’t explain exactly what it’s showing and why yet. This window shows two numbers about the production of each cargo type that is created by the industry – these are the total values from the last month of game-play. The first one is the total produced amount of potential cargo, and it varies due to internal factors of the industry. For example, during an economic recession there’s only half of the usual production. Meanwhile, the second value is the percentage of the produced amount that has been delivered to other stations. Sometimes industries may decide to keep back part of the production and not deliver it to any station, but we don’t need to worry about that for now.
Below are tables for each of the various environments and the industries which can be found in each along with what they accept, if anything, and what they produce, if anything.
|Factory||Livestock, Grain, Steel||Goods|
|Iron Ore Mine||Nothing||Iron Ore|
|Oil Rig||Passengers||Oil, Passengers|
|Steel Mill||Iron Ore||Steel|
|Food Processing Plant||Livestock, Wheat||Food|
|Factory||Rubber, Copper Ore, Wood||Goods|
|Copper Ore Mine||Nothing||Copper Ore|
|Oil Rig||Passengers||Oil, Passengers|
|Food Processing Plant||Fruit, Maize||Food|
|Sweet Factory||Sugar, Toffee, Candyfloss||Sweets|
|Toy Factory||Plastic, Batteries||Toys|
|Fizzy Drink Factory||Cola, Bubbles||Fizzy Drinks|
However, the tables can be a little daunting, can’t they? So for an example of how the various connections may work, below is a list of the industries in a temperate map which either provide or will receive cargo, or even both. A ‘→’ or ‘↔’ shows the direction which the cargo in parenthesis ‘()’ travels. To put things simply, the industries that are underlined represent a pick-up point, whilst the industries that are in bold represent a drop-off point where we would get paid for our delivery of the aforementioned cargo. Often there are industries which can serve both of these purposes and those are marked with both.
What does all of this mean, exactly? Well, to put it into the most simple terms, we pick up some iron ore at the Iron Ore Mine and take it to the Steel Mill. We are paid on delivery of the iron ore and then, when the Steel Mill processes the iron ore into steel, we can pick up the steel. We can then deliver the steel to a Factory and get paid for that delivery. When the steel becomes goods at the Factory, we can then pick the goods up and deliver them to a Town and get paid for that delivery as well. This means that we get paid three times along the aforementioned journey, but if we try this out in a real game, we will notice that how much we get paid is not the same for each trip. The amount we get paid is based on a number of different factors, including the cargo payment rate, amount of cargo, transit distance, and time factor, covered in Delivery Payment Rates.
