I've come across a weird paradox that I can't answer, I will explain it via the following thought experiment:
There is a space-train and an observer 1 light year apart with synchronised clocks. The train travels to the observer at just below the speed of light. In the reference frame of the observer the train is subject to time dilation and length contraction. When it arrives its clock reads 1 second as its time was basically standing still and the observers clock reads one year. From the trains reference frame it sees the 'observer' travelling towards the train at near light speed, so the train should expect to read the observers clock as 1 second and the trains clock as a year as the train sees the observer to have undergone time dilation. So what do the clocks actually read and why? The only way I can imagine the paradox with relativity not occurring is if both clocks read the same otherwise you could tell what speed you were going?
