Lesson 1Track Geometry Basics: Alignment, Slopes, Curvature an Dem Effect on Speed an OperationsDis part introduce horizontal an vertical track geometry, includin alignment, slopes, an curvature. It explain how geometry rule speed, comfort, energy use, an safety, an outline design limits, transitions, an maintenance allowances.

It link part pickin an spec to track stiffness, ride quality, noise, an maintenance needs over asset life.
Rail profiles, grades, an wear limitsSleepers an ties: types an spaceFastenin systems an clip performanceBallast gradation an quality controlPart faults an failure waysInspection, renewal, an record keepinLesson 3Track Support Types: Ballasted Track vs Slab Track — Buildin, Maintenance, an Suitable SpotsDis part compare ballasted an slab track, focus on structure, buildin methods, maintenance ways, an life cost. It explain where each support type fit best, consider speed, axle load, climate, an ground conditions.
