OpenGL Train Traffic Simulator

I want a simple train traffic simulator made in OpenGL. The application will simulate the Bucharest Metro line M2. (you can find its path in the pictures, M2bun) The app must show the trains running on the given path, stop at stations and stop at traffic lights. The app must also allow me to add or remove trains and to change the traffic lights colours (from red to green, or green to red, to stop or start the trains). The app must be 2d, and the design must be black and white, as shown in the "fl1" and "fl2" pictures below. As a help for you, i attach youtube links with: 1.
