Would had loved some russiand routes here on Trainsimulator. They both have high speed routes and also freight routes far away in Siberia. Heavy fueltrain in Russia:
wow a very polluting train throwing out lots of clag. 3 locos in front haulling and 3 banker locos. a very heavy train
You might find something here. I can really recommend the TEM diesel loco there, as good as top flight payware. http://railroadsim.net/ru/downloads/rw
