DLC (Downloadable Content) appears to be a very contentious subject in the world of train simulators.
Unlike other games, where DLC items are often required to "compete" (either via power or just looking the part), in a train sim, it is much more about expanding your experience with your favourite DLC loco/route/region. And since everyone has a different favourite, it means that there needs to be a LOT of DLC on offer to provide something for everyone.
Just as Apple doesn't list the total cost of all songs or apps in iTunes, in the same manner, no-one expects anyone to buy all the Trainz DLC listed on the Steam Store. You can think of the full list of DLC items as just one big "store" where you browse and pick the items you're interested in, while ignoring the majority of items that aren't your cup of tea (just like when you visit iTunes).
Another point often raised is the cost of the DLC items. The cost is related to the enormous amount of work that is required to make the items, along with the obvious "niche" train sim community following. Without a market of millions of players to buy all the various items, an individual DLC can sometimes look expensive.
Almost all the content in Trainz is made by people just like you - Trainz Community members. To help lower the prices on the DLC and still ensure that our content creators are rewarded for their efforts, we've put together a large range of bundles that offer 40 to 75% off, making it that much easier to access more DLC for less.
When you click on a DLC item you will see which Bundles it is also included in. The price shown to you is for the remaining items in the bundle that aren't already in your collection.
Here is a list of the Bundles currently available with prices ranging from 40 - 75% off:
Don't forget also that Trainz has a HUGE range of free-to-download content on the Trainz Download Station (DLS). There are literally hundreds to top quality routes, and thousands of locos to add to your collection without spending a penny (although we do encourage you to grab a First Class Ticket, which you can do for free this week by visiting your MyTrainz page).
To find DLS content, use the new Main Menu in-game filter, or open Content Manager and filter on Download Station, then begin to search and explore.
