Train Simulator - BR Class 35 Loco Add-On (DLC)

Let's be direct: this is a DLC add-on, not a standalone game. The BR Class 35 'Hymek' is a diesel-hydraulic locomotive that ran on British Rail in the 1960s and 70s, and if that sentence already means something to you, you are exactly the target audience. If it doesn't, this probably isn't your entry point into train simulation. The add-on drops a single locomotive class into your Train Simulator setup, and the value proposition lives entirely in how much you care about operating that specific machine with accuracy. From a systems perspective, what matters in any loco add-on is cab fidelity, physics modelling, and sound design. The Steam description references a fictional railcar context with over 70 km of varied lines, tunnels, and single-track sections, which is a reasonable amount of operational territory to work with. Multiple track types and changing scenery suggest the routing isn't just a straight corridor, which is a genuine plus for replayability. Single-track sections in particular introduce passing-loop timing decisions, the kind of small operational puzzles that keep simulation runs from becoming passive. Whether the AI traffic on those lines behaves sensibly is a real unknown given the near-absent review pool. The review situation is the honest problem here. Three total reviews at 100% positive is statistically meaningless. That's three people, not three hundred. For a strategy and sim player used to parsing patch notes and community wikis, the absence of a real feedback base means you're buying on spec. The developer, 汐留姉妹, is not a name with a large English-language footprint, and the Early Access tag signals that content is still being added. Future updates are supposed to bring more train types and additional track sections, which is either reassuring or a reminder that the current build is incomplete, depending on your patience for roadmap promises. Who should actually consider this: dedicated Train Simulator collectors expanding a diesel-hydraulic roster, players already invested in the base game ecosystem who want more British prototype content, and anyone specifically interested in the BR Class 35's real-world operational quirks translated into a sim environment. The 70 km of routes give you something to actually run, rather than a loco dropped into an empty sandbox. Who should wait: newcomers to train simulation, anyone expecting a fully fleshed-out experience given the Early Access status, and players who rely on community guides or mod support, since that ecosystem around this specific DLC appears thin at launch. The Early Access label deserves a moment of attention. In simulation DLC, early access usually means either that route content is still being built out, or that physics and cab features are being refined based on feedback. Given the roadmap mentions additional train types and track sections as future additions, expect the current package to feel like a foundation rather than a finished product. That's fine if you're buying in for the long haul and trust the developer to deliver. It's a gamble if you want a complete experience on day one. Diego, Scout Team
