I can see what your saying, Nicholas. Is this the 'observer based effects' part of the theory? Anyway, there are spinnies of trees, mysteriously placed every kilometer. Now, someone in a spinny sees the next, and mesures the distace correctly as 1km. On the train, however, they mesure it, again correctly, as 700m. Tada!
And is the dining table at the station or in the train?

Those in behind would be red-shifted, and those in front would bllue-shifted
