Pointless sign - Kettering

This from The Ninja...

Not sure if this is pointless, pointed or poignant!

Pointless signs - Peterborough

UPDATE: This from the Bois from Basil...

Lots of locally-based Polish agricultural labourers - and other Poles - use Peterborough station.

Is it 'pointless' to make sure they know it is illegal to trespass on the track?

Presumably the 'brytyjska policje transportowa' put this up to deal with a specific local problem. 

Doubtless death-by-railway is a grand final solution to the 'immigration problem' in some folk's unsavoury minds.  But it's messy and disruptive, don't you know!

UPDATE: This from London Dwelling Urbanite...

The railways are baffling enough for English speakers... 

Surely everyone else needs all the help they can get!

UPDATE: This from Alrey there Yet?...

I'm not sure why you considered a sign in Polish at Peterborough station to be pointless. There's a large Polish population in Peterborough, most of which have arrived recently although there's been Polish people in Peterborough since the end of WWII.

Now a piece on how ridiculous it is that there's no line Westwards south of Peterborough would be interesting!

UPDATE: This from Jamie Joyce...

Why is this pointless? 

Useful notice for Polish community to stay off the tracks!

Dear gówno compiler... (sadly owing to pressure of space Eye is unable to reproduce the rest of this valuable contribution from Admiral Sikorski. Ed)
