No, in an electrical circuit, the electrons themselves move quite
slowly; it's the information that travels at about c (0.7c or so for
most wire.)  In a tube full of marbles, the individual marbles move
very slowly and the info moves at the speed of sound (in marbles.)

Certain waveforms have certain component velocities higher than c, but
the info transfer is still c...
