How to Find Missing Content in Train Simulator


Error: Failed to create vertex buffer (D3DERR_INVALIDCALL)

This error message occurs when something 3D is trying to be created in Train Simulator. The main cause of this issue is your graphics card has run out of memory and cannot create the necessary model or scenery. Please use our Troubleshooting Crashes & Other Technical Issues Guide to make sure your graphics card is suitable for playing Train Simulator.


This can also occur when you minimise or Alt+Tab out of the game in Full Screen mode. If you need to access other windows/applications while playing, please set Full Screen to Borderless under Settings > Graphics. The selected resolution will need to match the native resolution of your monitor.

Why can't I access the game in Windowed Mode?

If you are having trouble accessing the game after changing to windowed mode, this is typically caused when an appropriate resolution for your monitor has not been selected before restarting the game. Next time the game tries to launch, it will be attempting to display an unsupported resolution. Therefore, you won't see the game window, only a tab on the taskbar. 


To resolve the issue, start the game in safe mode and revert your graphical settings to the last known working configuration, and remember to select a resolution supported by your monitor before restarting.

Starting Train Simulator in Safe Mode
  1. Open Steam and locate Train Simulator in the library.
  2. Right-click and go to Properties.
  3. On the General tab, and scroll down to Launch Options.
  4. Now enter "-SafeMode" without quotations in the text box.
  5. Go to Settings > Graphics, select a Full Screen mode and a resolution supported by your monitor (failure to selection a supported resolution will minimise the game to the taskbar).
  6. Press Save and close the game.
  7. You may remove "-SafeMode" once your game launches normally.

Error: Game failed to start [missing executable file]
