May 1986. All subsidiaries of the RFFSA were consolidated in 1983 with the introduction of the SIGO System by the federal government. GT22LC When most second and third world railroads couldn't operate standard EMD GT22s due to their weight, EMD introduced the GT22LC; which is the same as a GT22C, but now incorporated with a much lighter (L) frame to handle harsher conditions than normal while still equipped with a turbocharger. Due to the lightweight frame, the U or W suffixes no longer applied as the locomotive was designed to handle any rail gauge the locomotive is applied to. Production spanned from February 1985 to August 1986. GT22LC-2 Basically the same as the GT22LC, the GT22LC-2 now added EMD Dash 2 Electronics while still retaining a turbocharger. Due to the Lightweight frame, the U or W suffixes no longer applied. Production spanned from November 1981 to November 1996.
