Written by William C. Vantuono, Editor-in-Chief
Canada’s Transportation Safety Board (TSB) has determined that a draft key (“cross key”) failure caused the Jan. 26, 2021 derailment of a CN freight train near Edmundston, N.B. TSB said investigation report R21M0002 “draws attention to the importance of reassessing the design and inspection frequency of critical rail components, such as [draft] keys, based on changes in railway operating conditions.”
![“Thanks to Secretary Pete [Buttigieg], USDOT, the Federal Railroad Administration and all our partners for making the S-Line passenger rail a reality!!” NCDOT Secretary Joey Hopkins said in a July 1 LinkedIn post. “Thanks to the hard work of our NCDOT team we broke ground on the first construction project in the Raleigh to Wake Forest segment, a $19M project to grade separate Durant Road 7 months after the grant announcement!!” (Photograph Courtesy of Joey Hopkins)](https://www.railwayage.com/wp-content/uploads/2024/07/slinelead-315x168.png)
