New Regulations

This rule affects the positive and controlled hand-off of TIH/PIH chemicals, explosives and radioactive waste railcars between shippers and receivers in a High Threat Urban area (HTUA) as well as railroads interchanging in an HTUA. CSX has worked diligently to educate our crews and employees about the new regulation in order to be compliant before April 1.
