Train Sim World® 4: Flying Scotsman Centenary Edition

I spent a good stretch of hours inside TSW4 with a spreadsheet mentality, and the first thing that becomes clear is that this is not a casual arcade ride. Dovetail's SimuGraph vehicle dynamics engine means each traction type behaves differently: the LNER Class 801 Azuma on the East Coast Main Line between Peterborough and Doncaster runs with quiet electric authority, the Metrolink F125 diesel across the Antelope Valley Line between Los Angeles and Lancaster demands a different throttle discipline entirely, and the steam-era locomotives in the Training Centre are a genuine systems-management exercise where juggling two brake types under time pressure will humble anyone who thought train driving was just holding a stick forward. That mechanical depth is the core value proposition, and it lands. For newcomers, the Training Centre is the tutorial structure I wish more sims had. It issues certifications per locomotive class, walks you through diesel, steam, and electric power sequentially, and even provides historical context on each machine. The difficulty rating system on routes gives you a clear at-a-glance read on complexity before you commit. Once certified, the main gameplay splits into timetable mode (run scheduled services, hit precise stopping accuracy, stay within speed limits, avoid heavy braking penalties), Free Roam (spawn any owned locomotive anywhere, no signal restrictions), and a Scenario Planner that now lets you chain paths across different track sections, set weather conditions, add intro text, and spawn AI traffic at configurable points to create congestion. The upgraded Livery Designer and the Creators Club for sharing player-made liveries and scenarios add a community content layer that meaningfully extends replayability beyond the base routes. The elephant in the room is the annual release model. TSW4 arrived roughly a year after TSW3, and the base game ships with only three routes: the East Coast Main Line, the Antelope Valley Line, and the S-Bahn Vorarlberg crossing the German-Austrian border, which is the first international route in the series. That is lean for a full-price entry. The DLC catalogue is extensive and the add-on pricing per route is steep enough that critics have noted individual expansions can cost as much as a budget game. The saving grace for returning players is the cross-generation content import: DLC purchased for TSW2 or TSW3 carries over as free downloads, which is a genuinely player-friendly policy that transforms a sparse base into a substantial collection for anyone already in the ecosystem. On the technical side, TSW4 runs noticeably smoother than its predecessor. Volumetric fog, high-detail rain on windscreens, improved antialiasing, and enhanced AI traffic and pedestrian density all contribute to a more credible operating environment. The action points scoring system, which rewards correct configuration, safe stopping, and punctuality while penalising speeding, wiper neglect in rain, and rough coupling, gives every run a measurable performance read. That feedback loop is exactly what a sim needs to keep experienced players honest. The Creators Club's livery customisation, meanwhile, stops just short of competitive play. An online head-to-head timetable challenge mode would push the multiplayer side considerably further, and its absence is a reasonable complaint. For a first-time buyer, the calculus is straightforward: if timetable precision and locomotive fidelity sound appealing, the Training Centre will get you operational faster than you expect, and hundreds of route tasks will keep you occupied well beyond the initial routes. If you already own TSW2 or TSW3 content, this is the best version of that content library available. If you are brand new and want maximum geographic variety from the base package alone, the three-route offering will feel tight until you invest in add-ons. That DLC commitment is the most honest caveat I can offer.
