I ride trolleybuses every day. Sometimes they do lose connection with the overhead lines, most of the time this happens in places where the line splits into two separate lines. The bus stops, the driver goes out with rubber cloves and yellow safety west and pulls the pantograph back under the wires. The process of pulling the pantograph back takes a few seconds. However, the whole system seems to be flexible enough so that the trolleybus can easily drive on the lane next to the lane over which the electric lines are hanging.
A friend of mine, who happens to be a rail-fan, told me once that the trolleybuses have enough power in their batteries to drive a few hundred meters after the connection with the overhead lines is lost. But this is not a official information.
By the way, riding on the trolleybuses is fun. The acceleration of an electric vehicle is something cool, though its hard for the older people who happen to be standing
And into the topic, the NK trolleybuses seem to be quite old.
