Train Simulator - WSR Diesels Loco Add-On (DLC)

Let's be clear about what this is: a simulation add-on developed by a small Japanese studio (汐留姉妹) and published under the Dovetail Games umbrella, dropping diesel-flavored fictional rail operations into the Train Simulator framework. You get over 70 km of track spanning multiple lines, tunnels, and scenery transitions, with single-track sections that demand real timetable awareness if you want clean runs. It is not a grand open-world sandbox. It is a corridor-by-corridor exercise in precise throttle management, braking curves, and signal discipline. The fictional route design is the centerpiece here. Rather than recreating a real-world line with all the licensing baggage that entails, the developer built something purpose-made, which actually gives the track layout a slightly more tutorial-friendly structure than some of the more punishing real-route DLC packs. Gradients and curves feel deliberately varied enough to teach you the locomotive's behavior without throwing you straight into a complex timetable from minute one. For a newcomer to the Train Simulator ecosystem, this is a more forgiving entry point than, say, a dense commuter corridor with two-minute headways. Where it gets complicated is the Early Access status. Future content, including additional train types and presumably more operational modes, is listed as scheduled. That word "scheduled" carries real weight in a game with only three Steam reviews at time of writing. There is no Metacritic score, no large review base to triangulate against, and the development roadmap is not detailed enough to make confident promises about post-launch support. Depth of decision-making right now is limited to what the current route and diesel stock can offer, and if you are the kind of player who runs a 200-hour career and expects the AI traffic to surprise you, this package is too thin at launch. The mod ecosystem question is essentially unanswerable yet. The Train Simulator platform has a historically strong modding community, and third-party content can dramatically extend the life of any add-on. Whether 汐留姉妹's rolling stock integrates cleanly with community-built scenarios or route extensions is something that will shake out over time. Right now you are buying the base experience and trusting the roadmap. Bottom line for the strategy-minded buyer: treat this like you would a Paradox DLC in Early Access. The bones look solid, the route design shows craft, and the diesel handling gives you enough to learn and repeat. But the content footprint is small, the review sample is tiny, and patience is genuinely required if you want the full picture the developers are promising.
