Stop smooching!

That's the message of a new sign that went up outside a train station in northern England on Monday.

The goal is to stop departing passengers from pulling up in their cars at a crowded drop-off point and pausing to kiss each other farewell.

The sign shows a profile of a couple kissing, with a diagonal red line across their image.

Virgin Rail says it installed the sign while refurbishing the station after a local business networking group said the place had to become more efficient.

But profit margins may have been a factor, too.

Virgin Rail says that if passengers want to share an embrace before they part company, they should pay to park their cars nearby where they can kiss all they want.
