Train Simulator - BR 266 Loco Add-On (DLC)

The BR 266 Loco Add-On is a DLC expansion for Train Simulator, developed by 汐留姉妹 and published by Dovetail Games. It drops a fictional locomotive into a purpose-built route stretching over 70 km, featuring multiple track configurations, tunnels, and shifting scenery. If you are expecting a meticulously licensed real-world line with timetable accuracy down to the minute, reset those expectations. This is a fictional setting, which gives the developers creative freedom but also removes some of the historical grounding that hardcore rail sim fans tend to prize. From a simulation structure standpoint, the driving mechanics follow the Train Simulator template: throttle management, brake curves, speed limit adherence, and station stopping precision. There is no deep progression system or campaign framing here. You drive the route, you manage the locomotive, you repeat. That is the entire loop. For players who treat Train Simulator as a meditative experience rather than a goal-oriented one, that is perfectly fine. For anyone expecting scenario objectives, AI traffic complexity, or a tutorial that teaches locomotive-specific quirks, the add-on is thin on those fronts. The Steam description flags future content including single-track sections and additional train types, but as an Early Access release, those are promises rather than delivered features. The route design shows genuine effort in variety. Across 70 km you get tunnels, open scenery transitions, and what appears to be a mix of track types. That is a reasonable canvas for a DLC at this scale. The concern, as always with Early Access simulation content, is roadmap reliability. With only three Steam reviews on record at the time of writing, community feedback is essentially nonexistent, making it difficult to gauge how the add-on performs in terms of frame rate, signal logic accuracy, or how well the BR 266 model holds up under close inspection in the cab. From a depth-of-decision standpoint, which is where I usually anchor my analysis, this add-on asks very little of you strategically. There are no branching route choices, no operational scheduling decisions, no timetable management layer. The complexity ceiling is the locomotive itself: learning its brake response and power curve. If you are a Train Simulator collector building out a route library, or a player who specifically enjoys Japanese-influenced fictional rail environments, the BR 266 fits that shelf. If you are evaluating it as a systems-rich simulation with meaningful decision trees, it will not satisfy that itch. Mod ecosystem potential here is unclear. Train Simulator has a robust modding community in general, but whether this particular DLC and its fictional route attract third-party scenario creators is an open question with such a thin review base. Buy with that uncertainty in mind. Diego, Scout Team
