📋 About This Mod
The cement plant, Katers Sylva Industry passing track and all Sylva Interchange related mods work together. Please if you upgrade, upgrade all of them to the latest versions or weird stuff will happen.
Installation:
Install this mod with FUSE's installer, RailLoader or Railforge, but not UMM. Or unzip it and move the folder to the mods folder
This mod now consists of 3 sorts of files that you can choose and combine:
-
[]Katers. SylvaInterchange - the interchange inself in a 4,5,6,7 or 9 tracks variation[/]
[]Katers. SylvaInterchangeHumpYard - an optional hump yard in 6,8 or 10 track variation. The files marked -no int are just plain tracks. The default files here function as interchange tracks too. [/]
[]Katers. SylvaInterchangeShunterShed - an optional shunter shed at the east side of the interchange. It is just a shed, it is not a repair shop anymore like in previous versions (due to dodgy programming constructions that don't work under the new loaders like FUSE). [/]
This mod completely overhauls Sylva Interchange in a way that fits the landscape and location. South of the center main track, there is a 4 to 9 track 40 cars long interchange. Drag the cars up hill and sort them into the 4 to 10 track hump yard. The smallest interchange has space for about 160 cars, the biggest fits about 800 cars.
This mod is free for everyone.
If you enjoy it, you can optionally support my work via the donation button on my Nexus profile or via ko-fi.com/katertje.
Optional support helps offset software costs and allows me to continue spending time on projects like this, ongoing development and user support.
Also check out:
- Sylva Yard Turntable! This adds a turntable, roundhouse and engine service (with fueling / watering stations). It also provides a more separate lead in / out of the yards.
- yard sort component for this interchange, (see optional files to download this mod, and see CLB's Yard Sort)
If you see any improvements or want to share you experiences, let me know in the comments or look me up at discord (Katertje).
Not compatible with Alina's Sylva Wye and Alina's Sylva interchange.
And yeah: I have tried before to make this yard in-game configurable. Unfortunately, that caused to many issues. So the new style with separate files is the way.
Katers Sylva Interchange and Hump Yard is a map overhaul for the Sylva interchange, offering configurable sizes from 4 to 9 tracks for the interchange and 4 to 10 tracks for the hump yard, with compatibility for CLB's yard sort. It has 248 endorsements and was last updated in July 2025.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Solid community backing with 248 endorsements and over 25k downloads
- Flexible sizing lets you tailor the yard to your railroad's needs
- Works with CLB's yard sort, so you can automate sorting without breaking your setup
⚠️ Cons
- Requires reading the detailed description to configure properly—not a drop-in and forget mod
- Only overhauls Sylva, so if you're looking for changes elsewhere on the map, this won't help
- Compatibility with other map mods or future updates could be a risk, given it's a total overhaul
For railroad sim players who want a bigger, more functional interchange and hump yard at Sylva. If you're into realistic freight operations and use CLB's yard sort, this is a must-try. Skip if you prefer vanilla maps or don't need extra sorting capacity.
💡 Beginner Tips
- Read the detailed description carefully to understand how to set the track counts for the interchange and hump yard.
- If you use CLB's yard sort, make sure to install that mod first and follow any compatibility notes.
- Test the configuration in a sandbox save before committing to a full playthrough to avoid layout issues.
