The document provides a schedule for planning work related to the overhaul and testing of various locomotive systems for WAG7 locomotives. It lists the specific components and materials required for tasks related to relay rooms, transformers, bogies, pantographs, air brakes, compressors, and other systems. Assistance will be taken from other locations like ELS/LDH, DLS/LDH, and DBSI to arrange materials and send equipment for overhaul.
