Speaking of trains traveling at the speed of light, if the headlight of the train was turned on would it light the tracks in front of the train?

The light from the headlight would move -- you guessed it -- at the speed of light, regardless of the speed of the train.

"The light from the headlight would move -- you guessed it -- at the speed of light, regardless of the speed of the train."

So, if we were to measure the speed of the train plus the speed of the light, from a fixed reference on the train track, the total speed would equal... Not terribly intuitive is it?
