THE INVESTIGATION OF A TRAIN ACCIDENT YIELDS A SURPRISE CULPRIT WHEN CHARLIE CRACKS A CODE, ON "NUMB3RS," FRIDAY, FEB. 25

"Sabotage" -- While investigating a deadly freight train accident, Don and Charlie discover a shocking culprit who is on a mission to diminish public confidence in the railroad system, on NUMB3RS, Friday, Feb. 25 (10:00-11:00 PM, ET/PT) on CBS. Lou Antonio directed the episode written by Liz Friedman.

While consulting with the National Transportation Safety Board (NTSB) at the scene of the wreck, Don learns that this tragedy is one of a series of recreated accidents involving railroad negligence. As is the pattern with the previous train wrecks, an undecipherable numerical code is left at the site, which Don recruits Charlie to solve. By breaking the code, Charlie is able to establish that this accident was a recreation of a deadly wreck that left only one survivor several years ago. Don's investigation leads him and his team to a dangerous standoff with their suspect, who has surprising ties to the railway system.
