It never gets a chance to age comparatively, because by definition
neither 'clock' - nor the train, nor the station knows what the other
is doing, but it would not help if the train were to visit the station
in some metrical sense, since that would entail either time gained by
the train or lost by  the station and nor would it work the other way
around since it would seem to neither 'clock' that they had lost or
gained.

All the same, demons are thought to be able to travel at light speed,
so could in principle produce a twin-dial clock, available to both
station and train, although it is unclear how that could be of help to
anyone other than demons themselves unless they could become an
interstellar ISP. And if they got a useful role, they might get free
from messing things up and win a few prizes here and there.
