Hello everyone,
We're pushing live our next core update today, bringing a range of improvements across core routes and locos, as well as additional improvements to Cardiff City Network, San Bernardino, Maintalbahn, Frankfurt Fulda, Thames Link Class 700 and Pfälzische Ludwigsbahn.
Performance has been a particular area of feedback that we’ve continued to work on for core routes, and we’ve made some optimisations to try and mitigate frame rate drops and deliver an overall smoother experience.
The Class 150 has had a large overhaul to its audio, including engine running sounds, safety systems, cab interaction audio, as well as doors and brakes. We’d greatly appreciate any further feedback from these changes.
A Note On Birmingham-Crewe Improvements
From our previous announcements, we had planned a wider range of improvements for the recent Birmingham-Crewe route to align with this update; however, whilst these changes are still undergoing testing and quality assurance from our teams, we're taking more time to ensure they're ready to be released as you'd expect.
We apologise that we've not been able to deliver these improvements to the timeline we originally communicated, and we hope to have more news on when you can expect these in December. We're grateful for the feedback shared from the community, and we'll continue passing these notes to the development teams to support the route as best as possible when we're able to share the updates.
This update is currently being shared across all platforms, including Steam, Epic Games and PlayStation/Xbox consoles. Please allow up to 24 hours for the update to be available on your systems.
