Track Realignment and Rectification

Running trains over railway tracks are causing vertical and lateral forces which, over time, can affect track alignment and change incrementally the installed track. This causes track irregularities. This deterioration process on curved tracks is even more severe due to the additional effects of centrifugal acceleration. 

Track irregularities that are isolated require prompt maintenance to correct them. If there are multiple track problems or significant track irregularities that affect riding quality, then the maintenance actions required to correct them are more complicated and focus on the correction of the track geometry.

Track surveying

There are two main ways to realign an existing railway. The first method involves surveying the track using topographical optical equipment. This data provides an exact image of the track layout. It is used to define a design geometry that includes straights, curves, and transition curves. 

The current method is to use specialized software to analyze the survey data and run for finite sections.

Track Realignment and Rectification

Track Rectification is used to adjust the track on a particular curve. However, it can also be extended across the entire curve without changing the curvature or length of the alignment elements. 

The design versines of the track are used to determine the target results for the computation. This method proposes individual or consecutive slews and then evaluates their impact on the versine variation.

Track Realignment is a complicated procedure that alters the curvature and length of an alignment element. Realignment creates a new track alignment that can be used for speed increases.
