Notes:
Prior to 2004-05 route length data and electrification data was collected using various systems and collected on a semi-annual basis. These systems, whilst often the most accurate measures available at the time, would not have provided as accurate a measure as the GEOGIS system and there is therefore a break in the time series between 2003-04 and 2004-05.

There is a break in the time series between 2006-07 and 2007-08 due to a new methodology where the route classification reference data was revamped. There is also a break in series between 1993-94 and 1994-95 for passenger stations data only.
More details on methodology can be found in the quality report relating to this dataset: http://orr.gov.uk/statistics/published-stats/statistical-releases
 
The quality report pulls together the key qualitative information on relevance, accuracy and reliability, timeliness and punctuality, accessibility and clarity and coherence and comparability. It also includes information on some additional quality principles on user needs and perceptions, confidentiality, transparency and security of data.
