The first kissing zones emerged at American stations in the 1950s for wives to say goodbye to husbands heading to work.
But the village of Deerfield, near Chicago, hit the headlines in 1979 when it created a 'No Kissing Zone' at its station after complaints about passionate couples causing traffic delays.
A couple were arrested in India last September after claims their kiss outside a Delhi train station left commuters 'feeling bad'.
But an obscenity charge was overthrown by the courts earlier this month.
