Looking at the lead photo in that article I dont see how rail traffic can move effectively across that bridge given how badly damaged it is.

Also further down into that article it describes the record of the new Russian commander in Ukraine from his time in Syria. I'd hazard a guess that fighting close-knit rebel groups is quite different to fighting a national army.
