[quote]QUOTE: Originally posted by Overmod George745 -- halfway toyomantrains -- a) no, of course not, they're on the front of the locomotive where you couldn't see them no matter how much Lorentz-Fitzgerald contraction you had. b) it's highly unlikely he'll see the light from your ditch lights, as the frequency spectrum will be blue-shifted way the hell up out of the visible range. (He might see your train-radio transmissions, though, if your amplifier is good enough ;-}) Shrek -- I'd get a Cummins instead. [/quote] Actually you would. Physics tells us that the loco is moving at the speed of light . So is the headlight on the loco and yourself in the cab. When the headlight is turned on the light from the headlight will be moving at the same speed. Because you are also loco also moving at the speed of light, you would not experience the compression of the light waves. You will see the light. This same principal works with the Space Shuttle. The Shuttle moves very fast 17000 - 20000 miles/hour. If an astronaut steps out of the shuttle the shuttle does not move away because the both parties were and are moving at the same speed.
