My reminder from Kyiv.
Here you see an non-renovated ChS4; on the next three pics of me (n° 191869 - 191867 - 191865) you can see the renovated version of the same loco.
In picture 191870 you can see a non-renovated version of this class ChS4.
High speed passenger loco. Powered by AC 25000 volts. Maximum speed is 160kph. These locos were built by Skoda plant, ChSSR.
