They are attenuated along the line.
The transmission line acts as a low-pass filter, blocking high frequencies.
Different frequencies within pulses travel at different rates causing phase distortion of the pulse.
Spreading of the pulses, causing them it to interfere with other pulses.
Mismatches on the line cause reflections (and thus ‘ghost pulses’).
