OpenFront Factory Count Guide: How Many Factories to Actually Build

How many factories should you build?

There is no universal best number of factories. Build the first when you can connect it to a paying city or port and protect the route. Add another location when that location solves a specific network problem or opens a useful destination. Upgrade an existing factory when its location is already suitable and more departures are the improvement you want. Stop investing when defense, a working port, or the remaining match time makes another economic purchase less useful. Neither two factories nor three factories is a mechanical limit, and your army size is not the counter that determines train congestion.

Start by naming what the next building would do. A factory beside an established group of cities can start a local train economy. A factory in a second secure region may give that region its own departure point. A new position can also help connect stations that the first location cannot reach. Those are different reasons to build another factory, and each requires a suitable position on the map. “I have enough gold” does not identify a destination, improve the route, or protect the building. If you cannot describe the practical change, keep the gold until the missing part becomes clear.

Zero factories can be reasonable while your immediate task is surviving an attack or establishing coastal trade. One can be enough to operate a compact network. Two can be useful when you have two defensible areas with productive destinations. More can be justified on a larger map with several useful origins. These are examples of situations, not a recommended quota. Count the routes you can operate safely before counting the buildings you would like to own. A third factory can be an ordinary economic investment when it adds a viable route; it does not need a special endgame exception.

Before buying, follow a train from an existing factory if you have one. Confirm that it reaches a city or port and that the journey has a practical destination. Factories launch trains, while connected cities and ports provide station payments. A factory stop does not pay merely because another train reaches it. An isolated factory cluster with no valid destination does not dispatch useful trains, and adding levels does not create the missing destination. If this distinction is unfamiliar, read what factories do before making the count decision.

Your best next purchase may therefore be a connection, a protected station, or no building at all. Compare the result you expect after completion with the position you have now. Will another origin reach somewhere useful? Will that connection survive a border change? Does your reserve still cover the threat already approaching? These questions give a better answer than a fixed “build two and stop” rule. The factory economy commitment guide addresses the initial choice to invest in trains; this guide focuses on deciding whether another factory location actually improves that investment.

Compare a new location with an upgrade and the shared price

Factory and port purchases share a price ladder. Under normal settings, the early steps are 125,000 gold, 250,000 gold, 500,000 gold, and then 1,000,000 gold per step once the price cap is reached. Existing levels matter, not just the number of icons on the map. A factory upgrade uses this shared progression too. The cap limits the price of a step; it does not mean that a factory has a maximum of four levels. Read the displayed price before deciding, especially after upgrading or changing ownership of buildings.

Suppose you have exactly one level-one factory and one level-one port, with no other relevant levels. Those purchases occupy the first two steps, so the next factory, port, or relevant upgrade is a 500,000-gold decision. A reserve of 300,000 is not enough for that purchase. If you plan two factories and two ports from an empty starting position, with no upgrades or other changes, the four steps total 1,875,000 gold. This is why counting each building type on its own produces an unrealistic budget. The second factory and second port cannot both take the same cheap step.

An upgrade is not inherently cheaper per added factory level than a new factory. The practical distinction is location and dispatch behavior. An upgrade adds attempts at a location that already exists. A separate factory provides another origin, which may serve a different part of your network and has its own local dispatch timing. Neither option guarantees a fixed income increase. Choose the upgrade if the current location is protected and useful; choose a new building if the new location adds something the existing one cannot provide. Use factory upgrades for the deeper level decision.

The time needed to establish the investment matters as well. Normal construction takes 20 ticks for a factory, 20 for a city, and 50 for a port. Completion is only the start of the income process: a factory still needs a valid route, a train departure, and a paying arrival. These construction times are not payback times. A short building animation does not make it sensible to spend your last reserve while an opponent is threatening the area. Compare the whole sequence with the time you expect to keep the route open.

Keep the competing purchase explicit. If the same shared step could establish a working port, compare that trade route with the factory route rather than choosing whichever building is fashionable. A city follows its own cost progression and should be considered for its actual role, not treated as a flat-price income substitute. You can use port versus factory and how many ports to build to examine the alternative. The decision ends when you can name the purchased benefit, afford the displayed cost, and retain a reserve appropriate to the current threat. If any of those checks fails, defer the purchase.

Check the network, traffic, and reasons to stop

Train congestion depends on the number of Train units across the game, including the units that form each train, not the number of soldiers in your army. The saturation curve changes smoothly; its midpoint near 560 Train units is not a hard limit and does not make your third factory worthless. You should not look at a personal troop counter and use it to decide that factory investment has stopped working. More global traffic can affect departures, but the factory count decision still depends on your routes, costs, exposure, and time available to collect income.

The current small-economy boost also depends on your factory levels, not on having fewer than fifteen soldiers. It is strongest at the first total factory level and fades as the total reaches six levels. Each factory makes probabilistic departure checks based on its own level, with a minimum cooldown after a successful departure. Consequently, one extra level does not promise one extra train every fixed number of seconds. Do not extrapolate a short busy period into a guaranteed income rate, and do not interpret a brief quiet period as proof that another building is required.

Inspect the actual connection before expanding. Nearby-station discovery uses a range of 110, while an individual accepted rail path has a length limit of roughly 155.56. These are checks on connections between stations, not a maximum length for a whole journey. Intermediate stations can extend a network. Stations at a distance of 15 or less do not form that connection merely by being very close together. The placement preview and a completed trip are more useful than assuming that every nearby icon belongs to the same working route. See train network when a planned connection is missing.

Consider three practical situations. First, your only factory has no valid paying destination: repair the destination or connection before adding another level. Second, you have a working protected route and a second safe region with suitable stations: a new factory can be worth comparing with an upgrade even if you already own two. Third, an opponent is about to cut the corridor or capture the stations: retain resources for the immediate threat instead of expanding a network you may lose. None of these decisions requires a personal army threshold or a promise about exact payback time.

Change the plan when the map changes. In a team game, coordinate destinations and protection rather than assuming your teammate’s factory automatically solves your own budget. In a short match, the available collection window may be too brief for another route. On a large map, a new origin may help distant stations become useful, but extra territory can also expose more connections. Before each purchase, check the displayed cost, the intended destination, the actual connection, the protection plan, and the objective you could fund instead. Stop when one of those conditions is missing. Resume when you have a clear route and a practical reason for the next factory, regardless of whether it would be your first, second, or fourth.
