Cargo Lines

What Is Cargo Lines?

Cargo Lines is a hex-based railway simulation from solo developer Splenbit, based in Dortmund, Germany. It arrives on Steam November 27, 2026 at $11.99, with a free demo already playable. Linux ships at release alongside Windows, and the whole game is tuned for short runs: a full campaign region takes roughly 20 minutes, which makes it a natural Steam Deck pick.

The pitch is rail logistics as a planning puzzle, not an action game. You lay track hex by hex between stations, dispatch trains with a button press, and watch cargo move. New orders arrive with deadlines, the flow of goods shifts, and if you stop paying attention, two trains meet on the same stretch of track and collide. The layout you build decides what happens next. The game was designed, in the developer's words, for players who like planning more than reacting.

How to Play Cargo Lines

The Core Loop

Every region follows the same rhythm. Stations appear on the hex map and generate orders with deadlines. You connect them with track, then dispatch trains to pick up and deliver wagons. Each in-game week ends with an upgrade decision, and each region is a fixed-length mini-campaign. Deliver enough, keep a good rating, and the next region unlocks on the world map.

The loop is genuinely real-time: the store page stresses that new stations appear mid-run, the flow of goods shifts constantly, and the clock ticks down. You are never building in a frozen snapshot. A line that was optimal two minutes ago can become a bottleneck the moment a new station spawns beyond it or an order changes destination. Budget time to re-check the whole network whenever the map changes, not just the newest station.

Track is the scarce resource. That single constraint shapes everything. You cannot pave the whole map, so every line you draw is a line you did not draw somewhere else. The weekly question, repeated in different forms across the campaign, is whether to spend resources on more track, more orders, or an extra wagon, or to invest in the countermeasure the current region demands.

The Weekly Upgrade Decision

This is the strategic heart of the game. Each week you pick one upgrade, and the regions are built to make that choice uncomfortable. A region with heavy snowfall wants a snow countermeasure, but another route branch would raise your order capacity permanently. Because a region is only about 20 minutes long, the cost of a wrong pick is contained, and you learn the trade-off calculus region by region.

The developer's framing is worth repeating: the real challenge is finding the perfect trade-off, not racing a scenario. Speed is not the score. Route quality is.

Relaxed vs Challenge Mode

Both modes are available from the start, including in the demo.

Relaxed mode removes order deadlines entirely and grades you only on wagons delivered. This is the entry point for children, for players who want the puzzle without a clock, and honestly the right place to learn how track scarcity bites.

Challenge mode puts a countdown on every order. Trains need dispatching before deadlines lapse, and network mistakes that were cosmetic in relaxed mode now cost deliveries. If you have played any traffic management game before, start here.

Region Modifiers Are the Real Tutorial

Eleven regions, each with an obstacle and a matching upgrade. The announced examples: a river, a herd of cattle, heavy snowfall. Rivers reshape where bridges are worth building. Cattle create moving hazards on your lines. Snowfall throttles the whole network until you buy the countermeasure. Each modifier turns the same core loop into a different puzzle, which is how an 11-region campaign avoids repetition with a single mechanic set.

A practical habit: before laying your first track in a new region, identify the modifier and plan around it. The obvious shortest path often crosses exactly the terrain the region is punishing you for using.

Infrastructure and the Upgrade Catalog

The Steam description names the concrete tools your weekly decisions draw from, and each one maps to a specific terrain problem:

• Dynamite clears obstacles blocking the cheapest route. The alternative is routing around, which costs track — so dynamite is effectively a track-saving purchase in obstacle-heavy regions.
• Bridges cross rivers. River regions make bridge placement the whole puzzle: one good bridge can serve several stations, a bad one locks you into a long detour.
• Tunnels punch through mountains, the same track-saving logic as dynamite applied to elevation.
• Water tower supports operations on long routes; the natural buy once your lines stretch past what early infrastructure covers.
• Fence or cowcatcher answers the cattle and buffalo modifiers. A fence keeps animals off the line; a cowcatcher lets a train survive the encounter. Fence prevents the problem, cowcatcher tolerates it — that distinction is exactly the kind of trade-off the weekly choice is built on.
• Stronger engines and extra wagons raise throughput on existing track instead of expanding the network. When your routes are already well-placed but deadlines are missed on volume, upgrade the trains before you pave more hexes.
• More track and more orders are the growth options: extra capacity versus extra income, each raising the load the rest of the network has to absorb.

The catalog matters because it converts the weekly decision from abstract budgeting into recognition: see the region's obstacle, price the countermeasure against the growth option, and pick the one whose benefit outlives the current week.

Watch Your Junctions

Trains collide if you do not keep your eyes on them. Dispatch is one button per station, but shared track means shared risk. Two rules translate directly to the full game: avoid building a long shared trunk line that multiple busy stations feed into, and prefer loop or branch topologies so trains traveling opposite directions never meet head-on. When a collision risk appears, it is almost always a network design problem, not an attention problem.

Advanced Tips

Demo first. The free demo (Steam app 4725530) includes both modes and one of the 11 maps, with a handful of updates, tracks, and trains. Everything you learn about hex spacing and junction planning carries over at launch on November 27.

Let trains do the dispatching. The game lets you send trains to each station with one click. Do not micromanage individual wagons. Your lever is the track layout, so spend your thinking time there.

Convoys are rated on length. The press material notes convoys are rated on their length, which rewards deliberate routing of multi-wagon trains rather than many short shuttles. Long convoys need long clear runs, another reason trunk-line design matters.

Build for the region, not for permanence. Regions are mini-campaigns. A network that survives one region's modifier may be actively bad in the next. Treat each region as a fresh puzzle box.

Steam Deck sessions fit the design. Twenty-minute runs and click-based dispatch make this a couch game. The developer optimized it for Deck explicitly, and full gamepad support means it plays fine without a keyboard.

Price countermeasures against track. A tunnel or bridge is expensive up front but saves hexes every run through that terrain. Growth purchases (extra wagons, more orders) pay per delivery. In a short region, the infrastructure buy usually wins if it unlocks your best route; the growth buy wins if your best route already exists.

FAQ

When does Cargo Lines release? November 27, 2026 on Steam for Windows and Linux, priced $11.99 / €11.49 / £9.69.

Is there a demo? Yes, free on the Steam store page right now, with both relaxed and challenge modes and one map from the main game.

Is it like Mini Metro or OpenTTD? It sits between them. Smaller in scope than OpenTTD, more structured than Mini Metro: fixed regions, weekly upgrade decisions, and deadline pressure in challenge mode.

Does it have controller support? Full controller support, plus Steam Deck optimization. Mouse and keyboard works too.

How long is the campaign? Eleven regions at roughly 20 minutes each, so about four hours for a first pass, longer if you chase good ratings across the board.

What happens if two trains collide? Collisions are the failure the whole design warns about — the store page names it in the pitch line. The fix is network design: separate directions onto their own track, avoid shared trunk lines, and use fences or cowcatchers in animal regions.

Is there multiplayer? No. The Steam listing is single-player only, with Family Sharing supported.

Can I play without deadline pressure? Yes. Relaxed mode has no order deadlines and grades you on wagons delivered. It is a full mode, not a tutorial.

What upgrades exist? The announced catalog includes dynamite, bridges, tunnels, a water tower, fences and cowcatchers for animals, stronger engines, extra wagons, more track, and more order capacity. Each region's modifier points at which one matters.

Does it run on Linux? Yes. Splenbit confirmed Linux support at release alongside Windows.

Is it coming to consoles or mobile? Nothing announced. The current listing covers PC platforms only.
