In 1950, Lionel suggested when the GG1s approach a TOO-LOW tunnel use a  "pantograph skid". 

Not sure this will work with todays GG1s however.

I believe that's another new feature with their scale pantographs.  Previous scale GG1's from Lionel, ones with automatic pantographs, couldn't follow the typical varying heights of trolley wire when in the deployed position. 

With all the talk about the sparking, the synchronized arcing noise that goes along with it gets no notice.  Anyone familiar with street cars knows that resonating twang.  Not so much confined to the pans themselves, but an electric snapping echo that is transmitted along the trolley wire.  That sound feature alone adds much to the believeability of the sparking pans IMO.
