I am not quite grasping the implications of your text. Here is my preliminary assessment:
Santa measured the span of Rudolph�s antlers (one metre) as Rudolph boarded the caboose of the train aka the �Comet�. Santa noticed that Rudolph�s nose was on the blink, emitting a brief pulse of light precisely once every four seconds. Seeing the pulse reflecting off the trains shiny locomotive 2.5 seconds later, Santa deduced the length of the Comet to be half that (1.25 light seconds) or 375000 km long.
Twas the night before X-mass when to Santa�s great surprise he looked up to see Rudolph�s nose blinking away at the tail end of the Comet as it streaked across the sky at a velocity equal to 60% of the speed of light or (180000 km/s).
To Santa�s astonishment the Comet appeared to have shrunk to a mere 300000 km in length.
Santa was no less amazed to find that Rudolph�s nose was now blinking only once every five seconds and that it took the light from Rudolph�s blinking nose 2.5 seconds to be reflected from the locomotive. The reason for this delay is that from Santa�s perspective, the front of the train had advanced (180000 km/s * 2.5 s = ) 450000 km in the time it took the light from Rudolph�s nose to travel the length of and finally overtake the locomotive of the Comet.
