AC 238544 seems to have been involved in a recent mishap when photographed by Blair Smith at Steelton yard in 2001. This is one of 60 cars acquired in late 1997 by Wisconsin Central for pulpwood service and assigned to the ACR. It was originally one of a group of 150 cars built by National Steel Car in 1977 for Kimberly Clark and used to transport pulpwood logs to a pulp mill in Terrace Bay, Ontario. Eventually however this fleet was dispersed.
