I work as railway designer since 1996 using Softdesk, Autodesk LDD and Civil 3D. In 2008, I had secondment in Melbourne working at KBR for 3 months. This was the time when I first used Inroad and Inrail.
After that, I was back again to my Jakarta office. Since that I didn't use Inrail for railway design until my company, PT Dardela Yasa Guna, bought the new Power Rail Track (SS2) in January 2011. I think it is a marvelous software for railway engineering.
