SimRail - The Railway Simulator: Cargo Pack is a railway simulation expansion that lets you command powerful freight locomotives and manage massive cargo loads across detailed Polish rail networks. As a focused DLC for the base simulator, it emphasizes heavy freight operations with authentic equipment and challenging scenarios, appealing to those who crave realistic train handling in a simulation setting.
Gameplay
In this expansion, you step into the role of a locomotive engineer, primarily operating the ET22 electric locomotive, a robust six-axle machine with 3000 kW of power and a weight of 120 tons. Gameplay revolves around hauling heavy freight trains, often exceeding 3000 tons, using new wagons like the Falns 441V hoppers for bulk materials such as coal, Sggrss and Sgns containers, and Zas or Zaes tanks that hold up to 83,000 liters of liquids like gasoline or diesel. Advanced physics play a key role, simulating fluid shifts in the tanks that influence train stability and handling, especially on inclines or during braking.
Routes include mainlines where speeds reach 100 km/h and more demanding sections like the Silesian track from the Staszic mine, complete with steep ascents and strict speed limits. A standout addition is the functional ET22 engine room, where you can interact with internal systems for a deeper level of realism. The core loop involves planning routes, managing load weights, adhering to signals, and navigating real-world challenges, all grounded in accurate rail mechanics.
Game Modes
The Cargo Pack enhances the base game's offerings with new single-player missions tailored to freight transport. These scenarios test your skills in specific tasks, such as pulling loaded trains from mines, unloading cargo, and returning empty wagons at higher speeds. Each mission demands precision, from overcoming gradients with heavy loads to handling fluid dynamics in tankers.
Beyond that, the expansion integrates with the existing multiplayer mode, supporting up to 75 players per server. Here, you can coordinate with others using realistic radio communication, taking on roles like dispatcher or engineer in shared sessions. While the DLC focuses on single-player content, it enriches multiplayer by adding the ET22 and new wagons for collaborative freight operations across the 500 km of geodata-based tracks.
Key Features
One of the highlights is the historical accuracy of the ET22, modeled after the real Polish locomotive series produced from 1971, with over 1184 units built. New wagons bring variety to cargo types, from aggregates in hoppers to liquids in tanks, each with unique handling traits. The simulation extends to environmental details, like varying weather and track conditions, affecting traction and speed.
- Realistic fluid simulation in tank wagons alters train behavior.
- Interactive engine room for the ET22 adds immersion.
- Challenging routes inspired by actual Polish railways, including mine extractions.
- Support for heavy loads up to 3000 tons, pushing locomotive limits.
Is It Worth Playing?
For enthusiasts of detailed simulations, this Cargo Pack delivers a compelling experience with its emphasis on freight logistics and authentic machinery. It has earned mostly positive feedback, with 71% of 162 reviews approving its realism and additions.[[1]](https://store.steampowered.com/app/2868050) The base game maintains an active community, with hundreds of concurrent players as of early 2026.[[2]](https://steamdb.info/app/1422130/charts) Recent expansions to platforms like Xbox in January 2026 have broadened access, and ongoing support keeps the simulation fresh.
If realistic train operations excite you, especially with a steep learning curve that rewards mastery, it's a strong pick. However, those seeking casual play might find the complexity overwhelming. Overall, it suits dedicated simulator fans looking to expand their rail empire.
