See above.Can we say : “A non-stop train will be passing through the platform no.4. Passangers are requested to keep safe distance.”
The actual announcement is normally "The next train at Platform 4 will not stop. Please stand back from the platform edge".
The train for London will leave the platform no.5 OR The train for London will leave from the platform no.5 ? Please advise?
The train for London will leave from platform 5.
Note that we don't use "the" before "platform" and we don't bother with "number".
