Why a train-simulator catalog grows so large
A train simulator can be built more like a collection of interchangeable rail experiences than a single game with one fixed expansion. A scenic route adds a stretch of track and its stations, signals, and operating environment; a locomotive add-on supplies a particular train to drive. The two can be sold separately, so a player interested in both a route and the trains associated with it may need to buy multiple pieces of content.
That structure lets players choose the railways and equipment they care about instead of paying for everything in one package. It also means the catalog can keep expanding: new routes and locomotives become separate purchases alongside older releases. A long-running catalog can therefore contain far more content than any one player needs.
The price of “everything” is a different calculation
For someone choosing a few favorites, the modular approach offers control. For someone trying to own the entire catalog, every separate release becomes part of the bill. Small individual purchases can accumulate into a very large total when repeated across many locomotives and routes.
The headline total is also not necessarily what a typical player pays. Discounts, bundles, and which add-ons are currently offered can change the cost, and owning one route or locomotive does not generally mean owning the rest. The striking consequence is that a game can be affordable to enter while its complete digital collection costs thousands—a difference between buying the experience you want and buying every option ever added.
