What’s in this update
Hello, Captains!
Update 4.2 has just landed, and it’s a big one: full COI Hub integration directly in the game, modular ramps, a host of new train features, and major performance improvements. We’ve also put together a new trailer highlighting the key features, while this post takes a closer look at everything included in the update.
Important: If anything seems off after updating, use Steam’s Verify integrity of game files option. Several players on the experimental branch found that Steam had not applied the update correctly and left the game in an inconsistent state.
You can read all of the details about today's update on our blog post.
