Finally I have free time from my work and I finished a new project. An old grand-dad, which saw probably the whole world. I wanted to do this monster long ago, but hands were busy at something other...bla bla bla, will not go into details what. In the scene about 2 million poligons, locomotive about 1 million poligons. Time of render is about 12 hours at resolution 2700x3600. Probably a lot of details are not visible, but I will do some other positions of camera in the near time. Thanks to all for attention, pleasant viewing and success!
