This is the Motor Assembly Line, and it’s responsible for producing Steam Motors in Anno 1800. As you progress through the Engineer tier, this building becomes essential, since Steam Motors unlock advanced ships from the Steam Shipyard, and other late game production chains.

Description
This is the Motor Assembly Line, and it is used to produce Steam Motors in Anno 1800. To begin with, it sits at the very end of the Steam Motor production chain, making it the final step before Steam Motors reach your storage.
For the factory to run, it must be connected to an electricity supply, and it also needs a steady flow of Brass and Steel. Brass comes from the Brass Smeltery, while Steel is produced in the Furnace as part of the Steel production chain. When these materials arrive quickly and consistently, the Motor Assembly Line can work at full speed.
Once active, the Motor Assembly Line produces 1.33 tons of Steam Motors every minute. As a result, it becomes a key building for powering advanced ships, vehicles, and late game industrial chains.
What is produced
These are Steam Motors in Anno 1800, and they play a crucial role in the later stages of the game. As you advance into steam powered production chains, Steam Motors in Anno 1800 become essential for building advanced vehicles and machinery.
To begin with, they are required at the Steam Shipyard, where they help construct powerful steam‑driven ships. In addition, they are also used throughout the Steam Carriages production chain, making them a key resource for high tier transport and logistics.
When preparing for expeditions, Steam Motors in Anno 1800, offer valuable bonuses as well. Every 50 tons you bring provides +30 Navigation and +30 Morale, which can significantly improve your chances of success on tougher voyages.

Improvements
In this section, we will look at how to improve the productivity and efficiency of the Motor Assembly Line. To start with, the first step is placing the building in a good location. Keeping it close to the materials it needs, and close to your Warehouse, helps reduce travel time and keeps production running smoothly.
After that, we can focus on the Trade Union. Adding the right items to it can greatly boost the Motor Assembly Line’s output and overall efficiency, making it much more effective in your production chain.
Placement
In this section, we will look at where to place the Motor Assembly Line to maximise its efficiency. To begin with, we will place it close to both the Brass Smeltery and the Furnace. Keeping these buildings nearby ensures the Motor Assembly Line receives its materials quickly and consistently.
With the inputs close by, the factory can stay supplied and run at full speed. Now that the setup is clear, let’s take a look at this placement in action.

This is a simple of the placement of the Motor Assembly Line.
Trade Union
In this section, we will look at which items you can add to the Trade Union to improve the Motor Assembly Line. To begin with, these items can boost productivity, reduce workforce, or speed up production, making the factory much more efficient overall.
In addition, you can obtain these items from several sources, including trading with NPCs, completing quests, or going on expeditions. Each of these paths gives you a chance to collect powerful items that strengthen your production chain.
With that in mind, let’s take a look at these items now.
| Item name | Effects | Rarity/Notes |
|---|---|---|
| Calciner | +40% Productivity, -3 Attractiveness, +50% Chance of fire | Uncommon |
| Coal permit | +25% Productivity, +20% Attractiveness | Uncommon |
| Night pollution by-law | -10% Productivity, -40% Attractiveness | Uncommon |
| Heavy coal permit | +40% Productivity, +40% Attractiveness | Rare |
| Reverberatory furnace | +50% Productivity, -2 Attractiveness, +30% Chance of fire | Rare |
| Bechamel converter | +60% Productivity, -1 Attractiveness, -50% Workforce | Epic |
| Green’s law to postpone the apocalypse | -30% Productivity, -80% Attractiveness | Epic |
| Lord Footprint’s gargantuan smokestack act | +55% Productivity, +60% Attractiveness | Epic |
Layouts
In this section, we will look at the different layouts you can use for the Motor Assembly Line. To begin with, layouts are a core part of Anno 1800, and placing your buildings correctly is essential for good productivity and efficiency.
By arranging the Motor Assembly Line in a smart and compact layout, you can reduce travel time and keep materials flowing smoothly. With that in mind, let’s take a look at some layout options you can use.
Option 1
Here we can see a well balanced production chain for the Motor Assembly Line. To start with, this setup uses four Brass Smelteries, two Furnaces, and three Motor Assembly Lines. This mix provides the exact amount of Brass and Steel needed, so the chain runs smoothly with no extra materials and no shortages.
On top of that, the layout keeps everything moving efficiently. Both Steel and Brass flow straight into the Motor Assembly Lines, keeping them supplied at all times. Once the Steam Motors are produced, they go directly to the Warehouse and then into your inventory without delay.
Overall, this layout is simple, efficient, and perfectly balanced for steady production.

This layout will produce four tons of Steam Motors every minute.
Option 2
Here we can see a layout that is very similar to the one above. To start with, the main change is that this version includes a Trade Union. Adding it gives you the chance to boost productivity by placing useful items inside it.
Because of this addition, the layout becomes more flexible and more efficient, allowing you to increase output without needing to redesign the whole setup.

With no additions to the Trade Union this layout will produce four tons of Steam Motors per minute.
