simple, whichever is moving against the rotation of the earth. But it's irrelevant here. You must be a moron to post it here and the moderator is a bigger moron to disable abuse alert.

since they are running relative to the rest frame of the earth and considering that the coriolis force is equal albeit in different direction and assuming negligible wind speeds, i will think that they will wear out their wheels at the same time. relativistic effects are immaterial at typical train speeds.
