Train Sim World® 6: Thames Valley: Windsor, Henley & Marlow Branch Lines Add-On
Three 15-minute routes feel more alive than one 90-minute slog.
Train Sim World 6: Thames Valley adds three short branch lines—Windsor (2 miles), Marlow (7 miles), and Henley (4.5 miles)—operated by the Class 165 Networker Turbo. The Marlow branch features an interactive token system, and each line carries distinct character: royal castle views, riverside scenery, and a shuttle operation affectionately called the Marlow Donkey. Total of 11 stations, 5 scenarios, and authentic timetables.
Thames Valley succeeds not because it's a single grand route, but because it's three small ones—each operationally distinct, each with its own texture—which means the game lets you pilot the same commuter train on radically different psychological journeys within one package.
Across English reviews, the three-line format is framed as a strength, not a compromise. Multiple reviewers explicitly chose to pay full price rather than wait for a sale, citing the distinct charm and detail of each route as justifying the cost—a pattern rare in DLC commentary.
The shortness of routes (10–30 minute playthroughs) is described by English, Simplified Chinese, and one German reviewer in opposing terms: English and Chinese players see it as ideal for casual/commute play; the German sample views it as too repetitive for sustained engagement.
Scenery and atmosphere consistently earn praise even from negative reviewers. The token system and operational quirks (shuttle, timetables) generate engagement despite physical brevity, suggesting the value proposition centers on session structure and immersion, not mileage.
Floating assets, holes in terrain, and unfinished scenery—particularly on the Windsor branch—appear in negative and even some positive reviews. This is not universal (some players report no major glitches), but the pattern in the analyzed sample is consistent enough that buyers should expect rough edges. Whether they become dealbreakers depends on tolerance for bugs in an early-access-feeling expansion from an independent developer.

Three historic Thames Valley branch lines—Windsor, Marlow, and Henley—each with distinct operational character, modeled with period detail and served by the Class 165 Networker Turbo. Includes interactive token system, 11 stations, 5 scenarios, and an authentic timetable across all branches.
Players frame this as a quality-over-length package. They call out the distinct character of each route—royal castle views, riverside peace, quirky shuttle operations—and praise the scenery detail despite noting bugs. The shortness of the routes is sold not as a limitation but as a feature: perfect for fragmented play sessions. Price is defended as fair given the content density and polish, at least by those who didn't encounter major bugs.
“The three routes each have distinct charm: Windsor's royal castle views, Henley's peaceful riverside tracks, and the quiet, winding Marlow Donkey line with tiny village stops.”
“In particular the Windsor branch feels extremely rushed, with huge terrain issues, holes etc. In my opinion it should not have been released in this state.”
“Instead of driving the same service repeatedly, you get the 3 Great Western Main Line alongside the charming Windsor, Henley and Marlow branches. Each branch has its own character, making the route feel fresh even after many hours of play.”
“Normally I wait for DLC prices to be reduced in sales before buying but for this one I decided to pay full price and in my opinion this is the first route that is actually worth every penny!”

Best for
- —Commuters and shift workers who have 10–30 minutes to play and want a complete, satisfying session rather than a progression checkpoint.
- —UK rail enthusiasts and geography fans who value specific riverside and castle scenery over long-haul operational complexity.
- —Timetable mode enthusiasts who enjoy short, frequent services and operational quirks (shuttles, token systems) rather than mainline racing.
English reviews establish the three-route format as a deliberate strength: players explicitly defend paying full price and frame the shortness of each line as enabling casual, repeat-play sessions. The variety of scenery and distinct atmospheres (castle, riverside, shuttle) anchor the recommendation. Technical bugs are acknowledged but framed as secondary to the core appeal.
Simplified Chinese reviews confirm the price-to-playtime value proposition independently: reviewers note 69 RMB (roughly USD 10) is defensible for 10–20 minute routes, and explicitly compare favorably to other short routes (Wight Island). The token system and Marlow Donkey pub are highlighted as novel features. No major objections to shortness appear in this sample—it aligns with the casual-play use case.

Deep editorial analysis
The clearest tension in the reviews is not about scope or price. It's about what short routes actually enable. The official description emphasizes historical detail and three distinct lines. Players emphasize something else: the psychological reprieve of finishing a service in 10–20 minutes and still feeling the route was worth piloting.
One English reviewer noted they usually wait for DLC sales but paid full price here, calling it the first route they felt justified the cost. A Simplified Chinese reviewer echoed this—at 69 RMB, the price-to-playtime ratio is defensible because the *routes are so short*. Marlow becomes a shuttle operation (the Donkey), not a grind. Windsor curves up to Castle Hill. Henley stays peaceful.
The trade-off is visible: German reviewers found the branches too short to sustain engagement, and English detractors noted floating assets and unfinished scenery, especially on Windsor. But the positive consensus reveals something the marketing didn't emphasize: this DLC's strength isn't comprehensiveness. It's permission to do short, detailed, thematically tight runs without guilt. You're not trying to fill two hours. You're nailing a 20-minute commute that doesn't feel like filler.
The interactive token system on Marlow (first in TSW) and genuine operational quirks (the shuttle end-change at Bourne End, regatta-day timetables) create the illusion of depth despite physical brevity. Players forgive the bugs and incomplete scenery because the three routes feel genuinely different—not three copies of the same track.
