The Federal Transit Administration sent images of explosions and chemical attacks to workers’ homes in the form of a DVD. The 15-minute video, titled "Warning Signs", depicts theoretical attacks during this year's Republican National Convention.These graphic images unnerved New Jersey Transit conductors who feel they are being asked to play a law enforcement role they never signed up for. Xavier D. Williams, General Chairman of United Transportation Union Local 60’s 1,030 active members, said he was disappointed with New Jersey Transit’s failing to relay security plans for the convention to workers. 280 New Jersey Transit trains carry approximately 60,000 weekday rail riders into New York daily.
