SCARM 1.9

This is a comprehensive application meant to allow users to create models of railroad track plans and layouts.
The best part about this program is the fact that it offers a really easy manner of designing track plans. The interface allows the simple selection and positioning of all kinds of tracks, figures, and other elements. An unlimited number of tracks and objects from more than 190 libraries can be deployed on the plan with ease. Moreover, the tracks can be reshaped and curved with ease, and different heights and slopes for chosen sections of the track route are available for use. Semaphores, color light signals, and distance measurement options are also provided. Long story short, even if it's very powerful and feature-rich, anyone can use this tool, including complete beginners.

I also really like the fact that it allows the quick one-click preview of the created layouts in 3D view mode. Furthermore, even when complex railroad layouts with many train stations are loaded the program runs smoothly without requiring considerable computer resources.

Last but not least, you can export or print the created layout and share it with ease. Extensions like the cool Model Trains Simulator are also available.

In conclusion, SCARM, which actually means Simple Computer Aided Railway Modeller, is a must-have tool for model train fans and enthusiasts.
