Action
Notice of safety advisory.
Summary
Freight train length has increased in recent years, and while research is ongoing related to operational aspects of long trains, including brake system performance, it is known that the in-train forces longer trains experience are generally stronger and more complex than those in shorter train consists. FRA is issuing this Safety Advisory to ensure railroads and railroad employees are aware of the potential complexities associated with operating longer trains and to ensure they take appropriate measures to address those complexities to ensure the safe operation of such trains. Among other things, this Safety Advisory recommends that railroads review their operating rules and existing locomotive engineer certification programs to address operational complexities of train length, take appropriate action to prevent the loss of communications between end-of-train devices, and mitigate the impacts of long trains on blocked crossings.
