TRACK TYPES Railway tracks are classified primarily based KEY TOPICS on the materials and structural support systems 1. TRACK GEOMETRY used. The two main types of railway tracks are Track Geometry refers to the spatial ballasted tracks and slab tracks. arrangement of the rails and the layout that determines the movement of trains on the track.

TRACK ALIGNMENT It reduces wear on the rails and wheels directly affects the safety, comfort, and by distributing forces more evenly. efficiency of train operations. Proper alignment Cant allows for higher speeds on curves minimizes forces on the train, reduces wear on by balancing the forces acting on the both track and trains, and maximizes the train’s train. speed potential. FORMULA FOR CANT Types of Alignment: CALCULATION: A. HORIZONTAL ALIGNMENT: Refers to the position of the track in the horizontal plane (straight or curved). The design of curves in the horizontal plane must take into account train speed and the radius of the curve. Tight curves reduce speed, while larger radii allow for e = Cant (superelevation in faster, more comfortable train movement. meters) G = Track gauge (in meters) B. VERTICAL ALIGNMENT: V = Speed of the train (in m/s) Refers to the gradient or slope of the g = Gravitational constant (9.81 track (uphill or downhill). m/s²) R = Radius of the curve (in The design must consider the length of meters) trains, the power required to climb grades, and the need for braking systems CANT CALCULATION: on steep descents.

TRANSITION ZONES: Gradually increasing and decreasing the cant is critical for smooth operation. 5. ENVIRONMENTAL AND SAFETY CONSIDERATIONS ENVIRONMENTAL FACTORS IN TRACK DESIGN A. DRAINAGE SYSTEMS: Proper drainage is critical for track stability. Waterlogged soils can lead to track deformation, affecting train safety and track durability. Drainage design: Includes ditches, culverts, and under-track drainage systems to direct water away from the track. B. IMPACT OF TEMPERATURE AND WEATHER: Expansion and contraction: Rails expand in heat and contract in cold, which can lead to buckling or breaks if not properly accounted for. Designers use expansion joints and high-tensile steel rails to manage temperature fluctuations. Weatherproofing measures: Tracks in cold climates may need heating elements or special coatings to prevent ice buildup. NOISE AND VIBRATION: Tracks generate noise and vibrations, which can impact nearby residential areas and wildlife. Mitigation strategies: Include sound barriers, vibrationdampening sleepers, and quieter rail materials.
