Can driving be continued, in the event of burn-out of one of the cable shunts in the the pantograph?

Shunt links in the pantograph are crucial for the proper flow of heavy current. In the event that one of them fails, the other is loaded with the entire current, which risks it overloading and burning out. Continuing to drive in this situation is not permissible, as it may lead to a complete loss of power and the immobilisation of the vehicle.
