Regulatory Relief for End of Car Cushioning Units
Key claim: Freight cars may stay in service with oil droplets on an end-of-car cushioning unit if the unit still works and has an indicator showing it has not discharged; units without that indicator must still be repaired or replaced.
Abstract
(Rule · Transportation Department, Federal Railroad Administration) This rule amends freight car draft arrangement and end-of-car cushioning unit (EOCC) regulations to make permanent relief currently provided by waiver. The amendments will allow a freight car to remain in service if the EOCC is operative and equipped with a unit condition indicator (UCI) that indicates a non-discharged EOCC. This change will permit such EOCCs to remain in service despite the presence of clearly formed oil droplets on the unit. The amendments preserve the requirement to repair or replace an EOCC with clearly formed oil droplets if the unit does not have a UCI.
Why this matters
Cushioning units absorb impact between freight cars during coupling and slack action, and prior rules required removing cars from service for any oil leakage. By codifying long-standing waiver practice, the FRA reduces unnecessary repairs on units that remain functional while preserving the safety backstop (repair required) for units without a discharge indicator.
