A major, distinct chapter covering the full family of mechanized track maintenance equipment: Tamping Machines (with 3-point and 4-point lining methods) and Dynamic Track Stabilizers, Ballast Cleaning Machines (BCM), Track Relaying Machines and the Track Relaying Train (TRT), and Rail Grinding Machines (RGM). Each has its own pre-block, during-block, and post-block operational procedures, plus a defined maintenance and workshop support structure (CPOH, Zonal Machine Depot, Satellite Depot).
Real Exam Facts — Track Machines
- Tamping uses either a 3-Point or 4-Point Lining Method — 4-Point Lining is specifically used only for curves.
- CPOH (Central Periodic Overhauling Workshop) handles major scheduled overhauls; Zonal Machine Depot (ZMD) and Satellite Depots handle more routine, localized support.
- G&SR governs the movement and block-working rules for track machines, including specific precautions in Ghat sections and during night working.
