How to display if a railway company don't want anyone to get down to the railway track?

Stay on Platform

Warning! Stay off the track!

Warning! Never go on the track!

PASSENGERS ARE FORBIDDEN FROM ENTERING TRACK AREA

Tracks should be pluralized.

Warning! Stay off the tracks!
Warning! Never go on or near the tracks! (if the tracks are level with the pedestrian platform).

Here's a selection of similar signs.

I am not a passenger - just at the station to buy a newspaper.
Can I entering the track area?

the newspaper kiosk is in the building over there... there's no reason for you to wander over to the tracks...

Make sure you play hopscotch on that special third rail.

If the warning is a general one, and there are multiple tracks, maybe, otherwise I don't see anything wrong with 'track' meaning the pair of rails adjacent to the notice.

"Stay off of tracks" is illiterate.

In Britain, getting onto a railway track, whether from a platform or by some other route, is called "trespassing on the railway", and is a criminal offence (British spelling) punishable by a fine or imprisonment.

this is the legalese from the NYC Mass Transit Authority "Rules of Conduct"...

What signs should be displayed to discourage people from crossing railway tracks?

Signs in the most common languages and pictograms warning of the danger.



This could also function as a salutary dehortation to problem gamblers.



That could also function as an admonition to fetishists who cross the line.

For those who cannot read or understand pictures, perhaps wall art depicting massive, full colour stills of those who attempted to cross the tracks and failed, and big screen footage of the live action, would be a timely reminder.

Planting pots of red roses along the platform would provide some solace on occasion and otherwise make a lovely display x.

Thank you everyone. It seems that "STAY OFF THE TRACKS" is the most common expression.

But we concluded that below is the best.
"If you are not a train, even if you are not a passenger, you are forbidden from entering track area. If you are buying a newspaper, you must be intelligent enough to know if you are a train. If you are buying other items, and if you don't know whether or not you are a train and if you would like to enter the track area, don't hesitate to ask us if you are a train. If you are on the platform for any other purposes, and if you don't know if you are a train, please check if your mom is made of steel and has engines or motors."
