If you can, use my equations correctly.
x' = (x-vt)/g
t' = t/g

Stick of lenght L' in S'.
Want to measure it in S?
Measure front and back at same time t, so
{ dt = 0
{ dx' = ( dx - v dt ) / g
gives
dx' = dx / g
so
dx = g dx'
so
L = g L'
so it becomes elongated in the S-frame.
Nothing you can do about it.
Except perhaps if you measure the distances to the
end points at different times and then subtract the distances.
Marcel has very long trains ;-)

For instance, x=cT, thus x'=(c-v)T/g.
Consider a stick of length (c-v)t in S, such as x1=vT and x2=cT
x1' = (vT-vT)/g = 0
x2' = (cT-vT)/g
x2'-x1' = (cT-vT)/g = (x2-x1)/g
L' = L/g, L' being the length of the stick in S'. It is obviously
contracted.

If it is at rest in S', then it is measured to be longer in S.
So it is obviously elongated.

I will not repeat such elementary demonstration anymore.

You better don't ;-)
