There is a wave guide mode usually designated TEM (for transverse 
electric and magnetic field) that approximates typical transmission 
lines well. The wave speed is that corresponding to what plane wave in 
an infinite medium surrounding the conductors (presuming it to be 
homogeneous). The speed of the wave can be calculated using inductance 
and capacitance per unit length measured at zero frequecy.

That is a fact!
