Era 4 Cargo Engines

The fourth Era has 7 cargo engines named after ancient gods & heroes, with one being a bonus engine.

You can open new engines by using research points generated by the Laboratory building within your Train Station. Only when you've researched the required pre-requisites can you begin to develop the next engine. At the end of each era, a coupling system is available, allowing engines to transport goods from the next era.

If you want to compare all engines, have a look at our Cargo Engine Comparison article.

Note: No passenger engines are available to research on the American Dream scenario.
