False speed limits

[Loongeron]

On the Sendziszow-Katowice section, there are false speed limits on the entire route, not just in SP. Example in the screenshot. 
In addition, the speed limit does not match the schedule. The train is always late.

30 km/h - start of the local speed restriction

50 km/h - end of the local speed restriction and return to line speed assigned by W27 sign ( in this case it is 50 km/h)

Points are deducted for exceeding on this segment. Does this mean that it is necessary to comply with these restrictions?

The restriction clearly contains some kind of error. 
On a straight section 30. And the lateness is growing.

You have passed W8 sign, that installed before this (W9) sign at the braking distance (~1 km). This restriction is applied only for this small section (the next sign means the end of restriction). When your tail go through you can speed up to allowed line speed.

For reference page 86-87 and page 128 rys.14: https://www.plk-sa.pl/files/public/user_upload/pdf/Akty_prawne_i_przepisy/Instrukcje/Wydruk/Ie/Ie-1__E-1__2020_WCAG_.PDF (use translator)

Welcome to the railways.

Local speed restrictions for local reasons.

Could be to save foundations of nearby structures, buildings or bridges or other impacts that speeding trains may have.

And I heard at some point that the low speed limits around the coal plant are due to coal mining and the impact vibrations from long heavy trains may have beneath the surface.

Is this official information or thoughts?

I am familiar with the railway, and somewhere, especially in the fields, the limit of 60 seems strange to me.

I'm just offering some typical reasons for speed restrictions like the ones you've highlighted.

They are real restrictions, fully signed.

As for the coal mining comment - as I said, it was something I'd heard, I think on Fluffy's YT channel.  And Fluffy knows his stuff. 

Sorry if you find any of it hard to believe.

I wouldn't have asked this question if it wasn't reflected in the lateness. I drive according to the restrictions and am very late.

The area surrounding Katowice is known for unstable ground caused by excessive mining. There will be a lot of local restrictions on this route because of that.
