Russian goods trains in 4K going to Trans Siberian Railway

This is a test video in 4k format. In this section, freight trains go to the Trans-Siberian Railway. The length of the trains is too long to capture the entire train (it reaches 200 cars). Always happy to criticism! What better, to use real good camera FullHD 1080p/50 fps or smartphone with camera 4k/30 fps P.S. Siberia to right :o)
