As soon as North Charleston Mayor Keith Summey got word Thursday morning that a CSX worker was busy taking down new signs that the city had placed at problematic railroad crossings, he and an assistant grabbed a video camera, rushed to the scene and derailed the job.

In the video, Summey holds his palms up as he personally confronts the CSX worker, who explains that he is just following orders from his boss.

"Tell him if he wants to come take them down, let him come take them down. We'll lock him up," Summey tells the worker. "Tell him to call me directly."

CSX spokesman Garrick Francis said there was some confusion about whether the signs were on city or railroad property but that the railroad is cooperating with the city.
