CHS7 carries cargo structure, that the big rarity in Russia

This is a special case. This photo was shot on Scherbinka circular test route, which is used for testing various rolling stock (including new or experimental types of locomotives and wagons).
On this picture there is a new type of open-top cars (gondolas) on the test run. I guess that for test run they use any locomotive which is available at the moment. Or, maybe CHS7 was chosen becouse it's ability to reach 160km/h. Most our cargo locos have top speed 100km/h, but for particular test there can be need to measure dynamics of wagon behaviour at higher speeds.
