ITS App Version 5 Update for All Upcoming Addons

ITS App Version 5 is now a required update for all users installing or managing ITS WAP5, WAP7, WAG9, and future InTrainSim Addons. Available now on the Microsoft Store.

Published · Updated 28 September 2026, 10:53 AM IST

The ITS App Version 5 update is a mandatory installation for all InTrainSim users. This version introduces essential compatibility improvements that ensure smooth operation with the latest locomotive packs — WAP5, WAP7, and WAG9 — as well as all upcoming ITS Addons.

Updating to Version 5 is critical for maintaining installation reliability, addon recognition, and future content support. Without this update, certain new addons may not install or function correctly.

The update also enhances backend stability and prepares the app for next‑generation ITS content delivery. Users can download the latest version directly from the Microsoft Store:

Good to know before you choose

Pure ITS features are enabled only when the game is launched from the ITS App. Launching directly or through a third-party launcher starts the game without Pure ITS integration.

Products or routes that require another developer's own launcher may not operate alongside Pure ITS content. Please consider this if another launcher is essential to your setup.

App-based launching is a permanent part of the Pure ITS platform because it enables these enhanced systems. ITS may occasionally provide complimentary add-on editions at its discretion. Free versions of add-ons and included scenarios are not guaranteed. Purchase decisions should be based on the content listed with the product.
