The problem is that the train and the station if in the same universe
must run on separate days, because, if they both ran on the same day
at light speed, they would have converted mass in proportion to their
speed, so that neither would be able to achieve light speed, and, so
neither can achieve light speed on the same day. Even if either
managed to do it, there would be no universe left over for a second
attempt - unless time reversal were possible. With a system of
universal co-ordinates and no mass, they could come and go as they
pleased.
