As subtle as they generally are, RailSimulator has quietly rolled out a new major update for its expansive train simulator RailWorks, adding among other items the new Career System to the game.
The new mode as you would expect adds a career element to the title, offering up four new RailSimulator Career System Scenarios. The patch also brings several additions and adjustments of speed limits to a few areas in the game, as well as more screen resolution options and some other new items and fixes.
The file can be grabbed now by owners of the game through the Steam client. Word of warning though: the save file format has changed so once you update, your saves from the previous version will be gone. From the change log:
Railworks
- RailSimulator.com Career System® added
- 4 new RS Career System® Scenarios added

- Speed limits added to the Castle Rock route
- Speed limits on the Hagen-Siegen route updated

- A turntable has been added at Evercreech Junction on the Bath Green Park to Templecombe route
- Extra resolution provided
- Small ejectors fixed
Note that the save file format has changed so saves will be lost from the previous version.
