PARTS OF RAILWAY Flashcards
Provide a hard, smooth, and continuous surface for train movement with minimal friction.
Rail Sections
Maintain correct gauge distance between rails.
Support rails and evenly distribute load to the ballast.
Absorb vibrations caused by moving loads.
Sleepers (Ties)
Join rails end-to-end to form a continuous track.
Rail Fastening Systems
Provide a stable bed for sleepers.
Ballast
Form the groundwork for the railway track.
Support ballast and ensure proper drainage.
Subgrade and Embankment
Facilitate changes in train direction and manage intersections.
Ensure smooth transitions and safe passage.
Switches and Crossings
Connect individual rail sections.
Rail Joints
Manage water flow and prevent damage to the track structure.
Protect subgrade and ballast from waterlogging.
Railway Track Drainage Systems
Distribute loads evenly across the track structure.
Provide support and maintain geometry.
Track Bed
Reduce vibrations and cushion impacts.
Protect track structure and improve ride comfort.
Rail Pads and Under Sleeper Pads
Allow for rail expansion and contraction due to temperature changes.
Prevent rail buckling and ensure safe operations.
Expansion Joints
Provide electrical power to trains via overhead wires or third rails.
Railway Electrification Systems
