In working on the second part, I encountered difficulties in managing
the contraction of space.
As you can see in the animation
<
https://www.geogebra.org/m/a5gr8yr7>
I added the tracks with the sleepers (0 to 8) 0.866c apart from each
other.
But, in the station reference, this distance doubles, because the
tracks are not in motion and, therefore, are not contracted as in the
train reference (where they move).
And so, with the length of the waggon contracting by half (from 8 to 4)
and the length of the track sections increasing (from 1 to 2), in the
station reference the waggon is only as long as 2 sections of track and
no longer 8 as it was in the train reference.
It seems to me an excessive difference but, after having thought and
rethought it, it seems to me that it is just like that.
I just wanted to show you how my work is progressing and now I will go
on to implement the waggon motion in the station reference.
