Thanks All, I have started reading "Introduction to Spacetime Physics" by Taylor-Wheeler. Its very nice and engaging. I realize I had some conceptual misunderstandings which are cleared now, I'm about 4 chapters in

Can you recommend any good sources for a clearer understanding? preferably youtube videos

the train observer will see the station observer move rapidly (but not faster than c)towards the back of the train, and can conclude that he observes the event first, but not before it *happened* (not perceive) in his frame

I see, the observer on the station is "closer" to the event

Yes, that's because the ground observer is closer to the clock at the back, so you're saying he will observe it illuminated first by virtue of his position?

I know variations of these have probably been asked numerous times before, but I'm having trouble with this specific scenario. Imagine the classic Train Paradox, except instead of lighting strikes we have an observer at the centre of the train shooting laser pulses towards the rear (Event E1)...
