A notorious issue with cracked versions of Train Simulator is missing dependencies. Because a repack smashes 700 DLCs together, the game often loses track of shared assets (called "KUJU assets"). This results in pink, untextured trains or floating tracks. Fixing this requires manual file editing that takes hours.
The astronomical total price tag has naturally led to a dark side of the Train Simulator Classic community: the market for "repacks." These are pre-packaged, cracked versions of the game that claim to include all, or nearly all, of the DLCs for free. These are distributed through various forums and torrent sites.
Second, the business model of Train Simulator Classic actively fights against the “all-in-one” concept. Dovetail Games treats TSC less like a traditional game and more like a platform—a “digital model railway.” The vast majority of DLC is created by third-party partners (like Just Trains, Armstrong Powerhouse, or RSSLO). These developers set their own prices and receive a royalty on each sale. An “all DLC repack” would not just steal from Dovetail; it would steal from dozens of small, specialized development studios, many of which are one- or two-person teams for whom a single route’s sales represent months of rent.
Train Simulator Classic (formerly Railworks ) by Dovetail Games holds a peculiar record in the gaming industry: it has the most expensive complete collection of downloadable content (DLC) in history. As of 2025, if you wanted to buy every locomotive, route, and wagon set legitimately on Steam, you would need to spend thousands of dollars.
Train Simulator Classic is widely known as one of the most expensive games on Steam if you attempt to purchase every piece of downloadable content (DLC) available.
A repack is a cracked, unofficial version of a game that has been heavily compressed to reduce the download size.
