The Train Sim World Roadmap

Who’s ready to do this one last time for 2023!
Welcome back to the TSW Roadmap for December, it’s been an incredible year for us, and we always want to thank all of your in our community for getting involved, especially with our festive challenges and Photo Mode competitions, but also across the year with important feedback on our releases, conversations and discussions on new tools and your continued support with our improvements.
In this Roadmap update, you can expect more information on recent and upcoming releases, additionally you’ll be treated whole range of teasers for content coming up in 2024 due to (most) of the community challenges being completed. We’ve also got a special announcement for the West Somerset Railway route, bringing a whole host of new features to the content for free, and we’ll be diving into the community’s world to talk more on hot topics and highlight incredible work you’ve been creating this month!
Of course, we’ll also be live tonight (Tuesday, December 12th at 19:00 UTC) to talk you through this full article, find a stream event link at the end.
One final note, we won’t be releasing a January 2024 Roadmap, due to the teams being out of office over the holiday season. We’ll update you with information for releases through articles and look to share more news for progress on improvements in early February.

Content Up Ahead

Just before we jump into the future, let’s showcase the add-ons we’ve previously announced and what we have coming out this week.

Out Today – Skyhook Games’ Cargo Line Vol. 1 - Petroleum!

Just releasing today, a brand-new pack from Skyhook Games! Discover different freight traffic, on the Midland Main Line and Great Western Express, with Skyhook Games’ Cargo Line for Train Sim World 4.
You can also recap from the Skyhook Games’ Cargo Line Vol. 1 - Petroleum announcement article.
This release follows an extensive update to Midland Main Line, bringing a large range of improvements and fixes to the route, which you can find detailed later in this article.

SimTrack Studios’ Centro Regional Railways BR Class 323

Releasing this week, Simtrack are bringing the Centro livery to the current Class 323, with new additional features (interactive Stabling tail lamp, TSW4 rain window effects as well as a toggleable cab Hunslet the Bear plush!) as well as 5 new scenarios across the Birmingham Cross City route, which feature some additions to the environment such as Flashing Emergency Indicators.

Rivet Games’ Bernina Line: Ospizio Bernina – Tirano

In case you’ve missed it from our last Roadmap, we announced the Bernina Line, a scenic alpine adventure across the peaks of Switzerland and dipping into the southern terminus of Tirano, Italy.
This truly is a magnificent line, with the world’s steepest gradients - up to 7% at some points! We’ll be sharing more details and news of the release when we’re closer to the time on the other side of the holidays, but for now we have a few screenshots from Jasper at Rivet Games to give you before we go.
Jasper: “Driving along Lago Bianco in winter, you'll notice that the lake is actually frozen. This is one of the places where we spent extra time to make sure the winter is as close as possible to the real world. Enjoy breathtaking alpine scenery from the comfort of your warm cab.”
“With two Allegra trains meeting at Cavaglia, there's a little bit of time to admire the fall season. And with the authentic, alpine style station building of Cavaglia, how could we resist taking a couple of photos.”
“The moon is watching over Alp Grüm station, one of the places you need to stop. Don't forget to walk round the station building and enjoy the view from the balcony. Oh, and there's a little hike starting here that you can make...”
Thank you, Jasper! Keep an eye on our news articles for more information on the Bernina Line coming soon.

A Glimpse of the Future…

West Somerset Railway – Remastered

We’re not done giving just yet! Today we have another exciting announcement in the form of an upcoming free update to the West Somerset Railway Add-on, which brings a huge range of new service layers, a new timetable, brand new features across the route, an extension to the track at Norton Fitzwarren, updating the route to the TSW4 feature set, including ToD4 lighting and weather system, rain window effects on all WSR stock, an update to the MK1’s interior lighting and so much more!
Wow - we hope you’re excited! Let’s hand over to our Game Designer Liam who has been closely working on the changes for a breakdown of what you can expect:

A New Timetable

Alongside updates to the existing Diesel Gala timetable, we've added a brand-new timetable for the West Somerset Railway all about steam power!
Liam: “This new timetable is based on a steam gala day, players that own relating Add-ons (listed below) will be able to drive all of TSW’s steam trains on a variety of services, including shunting, stock moves, goods demonstrations, full route services, part route services and semi-fast services, along with a few other specials."
“The Flying Scotsman makes an appearance as part of the gala, adding multiple runs of the full line as a semi-stopping service. There's also a winter special based on a real West Somerset Railway winter service running through December. Players can drive a Jubilee Festive pulling a rake colourfully lit Mk1s and a Class 47 on the rear from Bishops Lydeard to Crowcombe Heathfield and back.”
“The Taunton Shuttle is also playable throughout the day. Players can drive the Class 150 from Norton Fitzwarren to Bishops Lydeard and back, with the AI taking over the mainline parts of the shuttles route."
“Mainline traffic has also been added as part of this update to both the original diesel timetable and the new steam gala timetable. Both timetables include HST traffic with the steam gala timetable including even more mainline freight and passenger services.”
“In total, with all the relevant Add-ons listed below installed, the new Steam Gala timetable includes 384 services, with 107 of those being playable services. Peak Forest will be required to run the main services along the railway, with extra services for those who own the Flying Scotsman, West Cornwall Local pack and West Cornwall Steam Railtour pack. See the list below for a full breakdown of all the layers and their required packs.”
Playable Layers:
  • WSR
  • Flying Scotsman
  • Peak Forest (4F, 8F, 6P)
  • West Cornwall Local (Class 150)
  • West Cornwall Steam Railtour (Christmas 6P)
AI Layers:
  • BR Heavy Freight Pack
  • Darlington Saltburn
  • DSN Class 20
  • Great Western Express
  • Leeds Manchester
  • Rail Operations Group BR Class 37/7
  • RHTT
  • Southeastern High Speed
  • WSR Class 33
  • WSR Class 52
A special thanks to the West Somerset Railway who provided details on the services and timings of one of their steam gala days. Because of their help the timetable in-game shares almost identical moves and timings of the real-life timetable, with a few exceptions made for gameplay reasons.

New Route Features

Liam: “As the new timetable is full of steam trains it felt natural to add working water towers and coal loaders to the route. A working water crane can now be found Bishops Lydeard along with 2 water towers at Minehead which are now functional.”
“There’s also a working coal loader at Minehead just outside the sheds. Parking the tender of a steam train over the dust patch on the ground will trigger the coal loading process. “
“Another route feature which isn’t steam train specific is the addition of working whistle boards for AI trains. Whenever an AI train passes one of these boards, the whistle will blow, adding that extra level of immersion. This feature will only work for trains with the whistle board feature added to them. As part of this update all Peak Forest steam locomotives (4F, 8F & 6P), and all West Somerset Railway locomotives, including the Class 33 and Class 52, have had this feature added. As for Flying Scotsman, this feature was included as part of the Winter Core Update for supported routes.”
Finally, as a brand-new feature to TSW, we’ve implemented new tidal effects to the sea. Get a short preview of this effect in a [Tidal Wave Effect clip](

New Scenery

Liam: “Probably the biggest part of this update to West Somerset Railway is the addition of the ToD 4 system along with an entire route overhaul to bring it to TSW4 standards. This includes new and updated foliage, new landscape material, new water and new snow.“
There’s also been a route wide scenery pass, from extra details being added to entire sections being rebuilt. These changes will make the route feel more alive while also being a closer match to the real-life railway. The era remains the same, depicting the line and region from around 2017 / 2018.
The areas around the stations have seen some of the biggest changes. Minehead town has been almost completely rebuilt to match closer to the real town. Some of the changes include new buildings around the town, a remodelled beach front and bike lanes that run alongside the track to the level crossing. Speaking of level crossings, all crossings on the route are now functional with working road traffic.
The harbour at Watchet has seen a massive overhaul with new sea walls, boats and a sea front walk which is accessible by the player. Be sure to take a seat on some of the benches added around the route.
Another big change is the station of Bishops Lydeard and the area around it. The surrounding industrial estate has been rebuilt along with the car park alongside the station. But perhaps the biggest addition is the shed south of the platforms. This was missing from the original route which was built just before this shed was installed on the real railway. But now with steam trains being added it felt like the perfect opportunity to add the shed as a place to store locomotives.
"It’s not just the route itself getting an update. All WSR stock, including the Class 33 and Class 52, have had the TSW 4 rain effects added along with the MK1’s getting updated interior lighting."
"That’s all the big points from this update to WSR. There’s plenty more about the route I’ve missed out but that’s up to the players to discover. I would like to thank everyone who has tested and helped get this update out"
Thank you, Liam, for all the information! We'll be back in the new year covering further details of this remastered route Add-on, including our plans for release, which will be free for Train Sim World 4 players with the West Somerset Railway route Add-on.

Community Talking Points

Frequency of Updates

After the release period of Train Sim World 4, we were shipping frequent patches, roughly every 1-2 weeks, that targeted key issues that came about with the release. These updates varied in size, from small changelogs up to large updates which included a wide range of improvements.
Our plan going forward from the start of the new year is to ship larger, more impactful patches that target a big suite of changes all at once, and cover range of content and core improvements, but at a slightly lower frequency than what we’ve had from release until now. The amount of time we put towards working on fixes and improvements won’t change, they will be bundled up into single updates, and so we’re not constantly requiring an update to TSW4, and we can focus on making sure each release is as stable as possible.
If we need to address anything urgently, we will still intend to do so at the earliest opportunity. As always, keep your feedback coming in, and we’ll continue the conversation of our progress across important community issues.
As a note, we will still need to release Pre-requisite patches for upcoming add-ons throughout the month, however we will make it clear in the patch notes that these will be supporting updates and not to be confused with our regular patches that focus on delivering fixes and improvements.

Free Roam Spawning Issues

We are aware of the various spawning issues with Free Roam where trains are not materialising in a valid state. One example of this is the BNSF SD70-ACe spawning with the screens turned off. Included in the first part of our Winter Core Update, which went live yesterday, were some initial improvements to address spawning issues regarding the Vorarlberg BR 185, and we have been taking note of the various affected locos raised by the community as well as our beta teams. One solution that may be able to help is using the “I Am Stuck” option in the menu, we’ve seen this be helpful in some situations, but it won’t fix all cases. Our teams are working on addressing these spawning issues, as well as additional improvements to Free Roam, and we will keep you updated on any changes we make.

Glossop Services

We’ve heard the discussions and reports that many services on Glossop Line being unable to be completed due to objective instructions not appearing soon after starting. We understand that for playing wishing to complete these affected journeys, this is frustrating, and we appreciate your patience while we investigate this issue and work towards a resolution.

Substitution Issues

Additionally included in the first part of our Winter Core Update was a change that should help substitutions appearing where intended, with relevant routes and content installed.
This is our first improvement to help solve the issues with substitution, we will be continuing to take on your feedback and reviewing how we can further address substitution issue with later updates.

PC Editor

We want to share again that our ambassador Matin, Aka TrainSimPlay has created a public TSW Editor Documentation spreadsheet, which has links to all of our official resources, a huge range of community resources, and plenty of tutorials/guides all in one place! They’ve labelled each section into different topics (Route building, Scenarios, Timetables etc) and so far have over 76 pages worth of documentation / support!
We are still working towards improvements for the Editor, and continuing to learn from the community and our third-party developers for what they need most. As mentioned in our last roadmap, the changes we currently we have a focus on will be:
  • Ability to package files for distribution (.pak files)
  • Landscape material usage
  • Rediscovery of files when re-loading the Editor
Continuing our trend of highlighting a selection of community projects we’ve seen on our PC Editor forums, check out these fantastic projects and their progress:
  • Stuttgart-Wuerzburg (Frankenbahn) Route by ‘BlackPulsar’
    A full route plan, with generated terrain and WIP screenshots of custom scenery assets!
  • New Timetable for the Tees Valley Line by ‘Fawx’
    A new TVL timetable, with an initial version available to download and try out, including 154 total playable services and content from Blackpool Branches!
  • Oberwesterwaldbahn Route by ‘RobertSchulz’
    An ambitious route project, spanning up to 78km with the potential for 28 stations! Robert has implemented terrain data and begun laying track – check out this project!
It is incredible to see so many projects beginning to really take off so quickly and seeing the praise & support from many members helping each other out. Whether you’re diving into the Editor yourself, or want to have a keen watchful eye over the community creations, be sure to head over to our PC Editor Discussion forum and find updates on more community projects, share your support / feedback, discover helpful Editor guides, FAQs and a growing list of shared resources!

Player Mods

We wanted to share that we’re still working on improvements to mod functionality in TSW4. As we mentioned in our previous update back in October, core mods seem to be in reasonable state, but mods for content add-ons need additional work. We’ve been using a selection of mods in our testing process to better understand how our updates may impact mods, and we’re still trying to understand how we can repair the affected mods when players moved from TSW3 to TSW4.
We continue to recommend that players who do mod content to be cautious for any non-core related mods as there is a risk of work going to waste if we need to update anything to implement longer term support for modding.
We’re working directly with active modders in our beta community, and we’ll keep you all informed on our progress when we have more.

Roadmap Livestream

Exec Producer Matt, and Community Manager Alex, will be talking about all the things we’ve featured above, and answering your submitted questions in the final Roadmap Live Stream of 2023! Get ready to be festive, the stream will begin from 19:00 UTC on our YouTube and Twitch channels.
Set your notifications on our December Roadmap Stream Event page
Have a question for us? Put it in our December Roadmap Q&A thread and we’ll answer as many as we can live tonight!

Wrap Up

So that’s the final Roadmap for 2023!
But it’s not all over just yet, our offices will be closed over the Christmas break, but we have a couple pieces of content for you to get stuck into before we hide away until January 2024!
Do not miss our upcoming Community Festive Stream Event on Thursday, December 14th, where we will be showcasing the winners of our 12 Days of Trains-mas Competition, hosting festive TSW gameplay, challenging you all to a Christmas quiz and finally revealing a special giveaway for over the holiday!
On top of this, later in the month we will be premiering a special 4UP relay-race challenge video and sharing our Train Sim World Tracked 2023 stats.
Aside from those bits, we wish you all a wonderful festive period with your loved ones, and we will be back in the New Year!
