BROOKLYN - (AP) - Long Island Rail Road's ban on platformsmoking begins today.

The Metropolitan Transportation Authority voted in September toprohibit smoking in most outdoor areas of LIRR stations.

For now, those who disregard the ban will get off with awarning.

The MTA told Newsday it's not clear whenthe grace period will end. When it does, violators will face $50fines and up to 30 days in jail.

The new policy complies with a new state law signed in Augustprohibiting smoking at outdoor "ticketing, boarding or platformareas" of the MTA's two commuter railroads - the LIRR andMetro-North Railroad.

Smoking inside LIRR trains has been banned since 1990.
