[p]For those who don't fancy catching up on the past articles however, we've created a special December 2025 TSW Roadmap asset that includes all of our new reveals in a single space, making it easier to see everything coming up in the new year![/p][p][/p][p][/p][p][/p][p]Whilst that concludes the end of our reveals for 2025, we still have a few final events running throughout the week before the holidays begin, and one final special surprise in store next Monday (It's not another reveal, but something we hope TSW players can make the most of!).[/p][p]We hope you enjoyed our announcements and festivities this year - We've having such a blast celebrating with all of you across our communities![/p][h2]Season of Reveals 2025 - Week 3 Drop[/h2][h3]Announcing: Neckartalbahn: Heidelberg - Neckarelz from TSG[/h3][p][/p][p]We couldn't be more excited to talk about this next German route reveal coming from our partners at TSG, because for the first time since the release of TSW4, this route will be bringing a brand-new Steam locomotive into TSW6 - the BR 23![/p][p] TSG: "The Neckartalbahn is a scenic, double-track, fully electrified mainline that winds through the picturesque Neckar valley in southwestern Germany"[/p][p]
"Known for its smooth curves, tunneled sections, and striking riverside views, the line blends efficient rail traffic with one of Germany’s most beautiful natural landscapes."[/p][p]
This route features 53km of track from Heidelberg to Neckarelz, decorated with 15 stations for you to explore, setting the year back to 1974.[/p][p]
Whether you're a fan of steam locomotion, or looking for a electric traction - the Neckartalbahn has you covered, supporting mutliple ways to experience traffic as you journey across the line.[/p][p] What does this mean for steam simulation improvements?[/p][p]Alongside the work for this add-on, the TSG team have been working on a series of improvements to the steam simulation physics to support the release, and are actively developing these for Neckartalbahn. These updates should also act as a generalised core improvement to steam physics that can support potential future steam content that our teams or third party developers may wish to create. Any existing steam content won't be impacted by these changes, however, we'll listen closely to your feedback as the work continues and keep you informed on progress.[/p][p]We don’t have any details to share about what these improvements to the steam physics will entail whilst the team continue development, but we will confirm them in roadmap articles when we learn more.[/p][p][/p][p]Now - Let's head back to the UK for our two remaining new announcements![/p][h3]Announcing: West Coast Main Line: Trent Valley from All Aboard Studios[/h3][p][/p][p]First up, let's hear from our friends at All Aboard Studios with an all-new UK route that seeks to further build upon the ever-growing West Coast Main Line in Train Sim World - Get ready for WCML: Trent Valley![/p][p]
Bridging the track between Crewe and Milton Keynes, this route links the end-points of other major WCML routes in TSW, with Crewe as a shared station from Just Trains' upcoming WCML: Crewe - Preston, and Milton Keynes as a shared end-point from TSW5's core UK line WCML South.[/p][p] [/p][p]Connecting these stations has been no small task, and this Add-on will bring the longest end-to-end UK route into Train Sim World 6, with a massive 108 miles to discover![/p][p] [/p][p]AABS: "Master modern traction with the Class 350/4 and cutting-edge Class 807, and experience a packed timetable of high-speed intercity, regional stoppers and heavy freight!"[/p][p]Please note: Screenshots shown contain layered trains from other routes and do not show the Class 807 included with the Add-on as it continues development.[/p][p][/p][p][/p][p]For everyone excited to continue the WCML adventure, we've got even more to reveal...[/p][h3]Announcing: Cumbrian Coast: Carlisle - Whitehaven from Just Trains[/h3][p][/p][p]Rounding off the new announcements for Season of Reveals 2025, the JT team are here to announce their latest expansion to their growing WCML network - with Cumbrian Coast: Carlisle-Whitehaven![/p][p]The development of the route is still underway, and today we have a couple of WIP grey-scale renders of the new Class 108 DMU included in the release the team were keen to share. We'll aim to keep you updated with new images in the months to come, but for today please enjoy these first glimpses and details from the JT team.[/p][p][/p][p]Just Trains: "Experience coastal running between Workington and Whitehaven, with 40 miles of rural scenery and sprawling industrial landscapes to explore!"[/p][p]
"We are also working on new wagons to include in the release, with freight and shunting operations planned across the route."[/p][p]Be sure to also check out the Just Trains In-Development blog page for frequent updates from their team on content, including historic facts and production insights which you may find interesting![/p][p][/p][p]And with the two UK announcements today from both All Aboard Studios and Just Trains, setting aside differences in eras, this means that Train Sim World will soon have a completed series of routes that take you all the way from the heart of London at the iconic Euston station, right through to Carlisle near the Anglo-Scottish border, with branches and networks to explore along the way!
