I took some pictures in Kazakstan recently. The catenery in the former soviet countries is very "soft", i e the weights who keep the wire in tension are wery light compared with Europe.
In Europe operators are good adviced to have video-records of the pantograph behavior when talking to the rail provider when the catenery have came down.
