Where to buy Train Sim World 7: Thames Valley: Windsor, Henley & Marlow Branches Route Add-On at the best price? As of 27 Aug 2026 this title has one offer, $17.99 at Steam.

There is nothing to compare, but we track this price daily and show how it stands against earlier readings, and a price alert will tell you about any drop. This is an add-on, so you also need the base game to play it. That costs $44.99 today, which puts the pair at $62.98. On PC you buy a key that you activate in Steam or another client, and this is the widest market we track, with more than a quarter of games carrying a keyshop offer.

About Train Sim World 7: Thames Valley: Windsor, Henley & Marlow Branches Route Add-On

Train Sim World 7: Thames Valley: Windsor, Henley & Marlow Branches Route Add-On - about the game

Train Sim World 7 Thames Valley Windsor Henley and Marlow Branches Route Add-On delivers a focused train simulation experience on PC. This add-on introduces three distinct branch lines in the Thames Valley region as a single package. Players operate the BR Class 165 Networker Turbo DMU in GWR green livery across short but operationally varied routes that connect to the Great Western Main Line.

Gameplay

The core loop centers on realistic driving of the Class 165 diesel multiple unit. True-to-life performance includes accurate suspension and handling characteristics for the Networker Turbo. Drivers manage acceleration, braking, and speed limits while navigating the narrow stretches of the River Thames and the scenic countryside. On-board announcements and passenger ambience add to the atmosphere during services. A functional token system operates on the Marlow Branch, requiring players to collect and exchange tokens at specific points. The Windsor Branch features frequent shuttles with quick turnarounds near Windsor Castle. The Henley Branch offers a near-straight run through riverside towns. The Marlow Branch includes a unique turnback procedure at Bourne End where the train changes ends before continuing to Marlow. Fast Travel allows quick movement between branches while Route Hop connects to the separate Great Western Express route at Slough, Maidenhead, and Twyford for main line extensions. Intricate lineside details and a total of eleven stations provide visual and operational depth across the combined network.

Game Modes

Training Center provides an accessible tutorial for new players to learn the Class 165 controls and branch operations. Five dedicated scenarios cover specific duties on each line. Timetable services deliver an authentic schedule across all three branches with services running at realistic intervals. Guard Mode lets players take the role of conductor on appropriate trains, handling door operations, passenger checks, and departure signals. Journey Mode combines training exercises, scenarios, and timetable services into sequential chapters that track progress and performance. Additional timetable layers introduce variety such as a Class 37 railtour, Class 70 engineering works train, and GWR HST AI traffic through the connected main line stations. Free Roam supports exploration outside scheduled services. The package supports Livery Designer, Formation Designer, and Scenario Planner for custom content creation and sharing through the Creators Club.

The Routes

The Windsor Branch runs two miles from Slough to Windsor and Eton Central with elevated tracks that curve toward Castle Hill. This shortest line sees busy commuter-style shuttles. The Marlow Branch covers seven miles from Maidenhead through Furze Platt, Cookham, and Bourne End to Marlow, incorporating the historical amalgamation of earlier railways and the token signaling system. The Henley Branch spans four and a half miles from Twyford through Wargrave and Shiplake to Henley-on-Thames, known for its proximity to the Thames and seasonal riverside activity. All three lines remain operationally independent yet share the same traction and scenery elements. The combined package totals eleven stations with detailed environmental features that reflect the historic character of each branch.

Is It Worth Playing?

This add-on suits players who enjoy detailed single-player train simulation with an emphasis on branch line operations and procedural variety. The inclusion of Guard Mode alongside standard driving expands the roles available. Journey Mode provides structured progression that links different activity types. The three-in-one format offers distinct operational challenges within one purchase, including the token system unique to the Marlow Branch. Current support through the broader Train Sim World platform includes compatibility with later editions and tools for custom content. Those seeking realistic UK rail experiences with scenic Thames Valley views and precise timetable adherence will find the package aligns closely with those interests. The simulation prioritizes authentic handling and station procedures over high-speed main line running.
