Describe the operational difference between track lining and track raising.
The operational difference between track lining and track raising lies in the direction of adjustment and the specific track geometry being corrected. Track lining involves adjusting the horizontal alignment of the track to correct deviations from the desired straight or curved path. This process ensures that the track is properly aligned laterally, providing a smooth ride and preventing excessive wear on the rails and w....

“The operational differnecbetween track lining and track raising lies in the direction of adjustment and the type of track geometry correction each process address. The main purpose of the track lining is to correct horizontal alignment of the track . The track is shfted sideways to restore its correct position along the designed centerline. It is used to fix lateral devitaions such as kinks and curve distortions., misalignments due to ballast movement or gorund shift and performed using tamping machines. While track raising is to correct the vertical alignement and elevation of the track. The track is lifted upward and abllast s packed underneath to support the new height. It is used to fix issues like settlemetn dips, uneven cross level, poor drainage area. it is also performed using tamping machines.”
