What is an LCO file?

LCO files mostly belong to Trainz Simulator. LCO files are used for two distinct purposes.
For one group, these files are locomotive files used in train simulation software. They contain model data and settings for engines in programs such as Trainz Simulator and Microsoft Train Simulator.
For another group, LCO files work as LaTeX letter templates or letter class option files. They include formatting commands used by document preparation systems (for example, with scrlttr2 in KOMA-Script).
  • Locomotive files: View and manage them in the simulation environment. Check details at the Trainz Portal.
  • LaTeX letter templates: Open these as plain text with a LaTeX editor or text editor. More info is available at LaTeX Templates and KOMA-Script.
  • FilExt.com note: Note that even though both file types share the same extension, they contain very different data and serve very different functions.

    How to open LCO files

    You need a suitable software like Trainz Simulator to open an LCO file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LCO file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LCO file directly in the browser:. Just drag the file onto this browser window and drop it.
