Operation RedBlock is a union-initiated management-supported program that uses peer involvement to prevent employee use of alcohol and/or drugs while on duty or subject to call.

Currently more than 3,000 operating employees at CSX are trained as prevention committee volunteers. Volunteers participate in ongoing self-initiated activities and projects designed to educate co-workers about Operation RedBlock.
