We have not so many real routes...
The Kiev-Fastov is real route, but it seems you have seen it
The Kievsky Hod (Moscow-Kiev) is makeing as semi-real route actually, because is't very hard and complicated to make a real route, especially 900 km length ))
A many of real routes was began and was not completed, such as: Minsk-Borisov, 76 km length.
