Notes:
The measure Good Track Geometry (GTG) is based on the proportion of track where the lateral alignment and vertical alignment is categorised as 'good' or 'satisfactory'. In recent years, there have been improvements to the measuring technology, changes to the way the data is stored and processed, and changes to the rules calculating GTG. Therefore, results for 2007/08 and 2008/09 have been recalculated to be consistent with current methodology. Please note that results prior to 2007/08 have not been recalculated.

Increasing values of GTG indicate improvement.

Where historical data is shown, the data has been stated to reflect what Network Rail published in the previous year's Annual Return, this means that the previous year's data has not been refreshed (unless advised by Network Rail).

This data has been validated by Network Rail.
 
The most updated data for this table is now available from Network Rail’s latest Annual Return publication which can be found at https://www.networkrail.co.uk/publications/Annual-return
