ROCKVILLE CENTRE - The LIRR no smoking ban has gone into effect on platforms and officials say if commuters are caught they will face a $50 fine.

The ban went into effect yesterday and prohibits smoking near outdoor ticketing areas and train boarding areas.

Along with signs and MTA Police issuing warnings, there are also public service announcements on the train platforms to let people know that smoking is prohibited, which has drawn a mixed response from Long Islanders.

MTA police will issue warnings for an undetermined grace period and then will start handing out tickets.
