Train Simulator - BR Regional Railways Class 101 DMU Add-On (DLC)

Train Simulator - BR Regional Railways Class 101 DMU Add-On is a niche cab-driving simulation developed by 汐留姉妹 and published under the Dovetail Games label. Despite the BR Regional Railways branding suggesting a British prototype, the actual product appears to be a Japanese indie rail sim built around a fictional route network stretching over 70 km of track. You sit in the cab, manage throttle and brake inputs, and work through tunnels, open sections, and scenery transitions that change as you progress along the line. If you are the kind of person who finds satisfaction in hitting a platform stop marker within half a metre, this is the genre for you. From a systems perspective, the sim is in Early Access, which means the content slate is incomplete by design. Single-track sections with passing loops and AI traffic encounters are listed as planned additions, not yet delivered. Right now the core loop is straightforward: select a service, drive it, repeat. There is no timetable management layer, no dispatcher AI to negotiate with, and no branching decision tree that would get a strategy fan excited. What is here is the raw driving discipline, which is genuinely absorbing for a specific type of player but will feel thin to anyone expecting a full operations sim. The review count is nearly non-existent at time of writing, so community wisdom about performance optimisation, controller compatibility, or hidden difficulty curves is basically absent. That matters for a simulation product where community guides and mod ecosystems usually carry a lot of the onboarding weight. There is no mod pipeline confirmed, no scenario editor visible, and no tutorial quality data available. For a strategy-minded buyer who wants to know whether the game respects newcomers, the honest answer is: there is not enough information yet to say. Who should look at this? Dedicated rail fans who enjoy cab-riding for its own sake and are comfortable buying into an early-stage product with the expectation that content arrives over time. If you have already exhausted your hours in more established train sims and want something different in flavour, the fictional Japanese-inflected route design offers a change of scenery. If you are new to the genre or want a structured, content-rich experience from day one, wait for a later build with more routes, the promised single-track AI traffic, and a larger player base that can produce guides and community feedback.
