Depot Retrofits

Depots and maintenance buildings get levels. A level widens the maintenance radius, raises the number of vehicles maintained, or cuts pollution, noise or upkeep. You buy each level in the building's window. HOW IT WORKS - Open a depot or maintenance building and choose the Retrofit tab. It shows your company rank, the building's radius and vehicles, and one card per retrofit: the level, the upkeep after the next level, what the next level changes, and a buy button with the price. - Each level is bought on its own, for money. A retrofit's highest level is your company rank, up to 15. When the next level needs a higher rank, the button shows "Rank N" and is greyed out. It is also greyed out when you do not have enough money for the level. If your money drops below the price just as you click, the level is not bought, nothing is charged, and a yellow note says "Not bought: not enough money" until you have the money again (at least 10 seconds). When something built after the building stands in the way, such as a town building next door or a road rebuilt in front of it, the game cannot rebuild the building: the level is not bought and nothing is charged. A yellow warning then shows at the top of the tab, and what is in the way shows in red. Pause the game, clear it and buy again. If you cut a road off, build it again after buying. - Buying a level rebuilds the building. Within a game day, the game reassigns the vehicles it maintained; some or all of them may go to another building in range. Lines are not affected. - The game's own rebuilds keep the levels, for example electrifying a rail depot or adding stalls to a Roundhouse. - Levels cannot be sold or lowered. They are saved with the game. THE FIVE RETROFITS - Maintenance radius: +5% per level, or at least +10 m (+75% or at least +150 m at level 15). - Vehicles maintained: +10% per level, or at least +1 vehicle (+150% or at least +15 vehicles at level 15). - Pollution: -5% per level (-75% at level 15). - Noise: -5% per level (-75% at level 15). - Upkeep: -5% of the total upkeep per level (-75% at level 15). - Pollution and noise levels lower only what the building itself gives off. Vehicles keep their own pollution and noise. The pollution overlay map uses a decibel scale and averages over a few minutes of play, so at the full 75% reduction the pollution map shows only 2 to 3 steps less next to the building. - The town window shows the effect best: the Pollution Rating graph at the bottom of a town's pollution card follows the whole town's pollution. Expect a real but small change: stations and tracks often give off most of a town's pollution, and the mod does not change them. In a test, pollution level 11 on all 12 depots and maintenance buildings inside a town's borders raised the town's rating from about 41% to 50% over the next two years; the town stayed at Mediocre. The list of pollution sources above the graph shows shares of the town's total, which jump whenever an industry starts or stops producing. COSTS - Level 1 costs 15% of what the building would cost to build today (10% in the noise retrofit, 6% in the pollution retrofit, 25% in the upkeep retrofit), and each level after that costs 15% more than the one before (12% more in the noise retrofit, 10% in the pollution retrofit). - Each level in the radius or vehicles retrofit adds 15% of the building's normal upkeep, each noise level 10% and each pollution level 5%. The upkeep retrofit cuts the total upkeep by 5% per level. With the other four retrofits at 15, a full upkeep retrofit pays for itself in about 12 game years. WHICH BUILDINGS - All road, tram, rail and water depots and maintenance buildings, including ones built before the mod was added. Depots from other mods get the tab too when they use the game's depot icons, are marked as a depot in their construction file, or sit in a depots/ folder. - On a depot built from modules, such as the Roundhouse mod's, the levels also cover what the modules add: their vehicles and their upkeep. - A newly placed building starts at level 0 in every retrofit. NOT CHECKED YET - What happens to levelled buildings when the mod is removed from a save. Keep a backup of any save you play with the mod. COMPATIBILITY - Works with TRM: Industry Emissions in either load order, and both mods' cuts to pollution and noise apply. With version 1.2 or earlier, load Depot Retrofits after it. - The mod replaces no game script. It wraps each depot's own build script: the depot is built as its author made it, and then the levels are applied. - It contains no files from the game.
