Metro is taking steps to fight sexual harassment of riders on its buses and trains, with plans to start an awareness campaign in stations early next month, after creating a public relations quagmire on the issue.

The signs are part of a multi-part and fast-tracked push to fight harassment that ranges from unwanted cat calls to groping to flashing and even rape that advocates say they’ve been trying for years to get Metro to notice. Earlier this month, Metro created an email portal for reporting such cases and already has received four reports. It has formed a task force and plans to train workers on how to take riders’ complaints more seriously. Two plainclothes police officers recently accompanied a woman who reported inappropriate comments on her evening commute for two days.
