The abbreviation TRK stands for "Track" within the context of the US Railroad General Code of Operating Rules (GCOR). In railroad terminology, "track" refers to the physical infrastructure on which trains run, comprising rails, ties, and other related components. It serves as a critical identifier in various operational communications, ensuring that personnel can accurately convey information regarding locations, track conditions, and maintenance activities.
