'xx_raw.geojson'
This contains the raw data for the railway lines generated using overpass turbo, with data gathered from OpenStreetMap.

'xx_lon_lat.txt'
This file contains the processed data from 'xx_raw.geojson' which has been lineraly interpolated to combine the multiple data points for the rails in the selected lines into a single continuous path of geographic coordinates that traces the line.
Columns are geographic longitude followed by geographic latitude.

'xx_blocks.xlsx'
This spreadsheet details the number, location and length of each track circuit block in the line.
These were estimated using the Network Rail Section Appendix (https://www.networkrail.co.uk/industry-and-commercial/information-for-operators/national-electronic-sectional-appendix/) and information from live signalling information map Traksy (https://traksy.uk/live/).

'xx_block_lon_lat.txt'
This shows the geographic coordinates of connections between each track circuit block.
Columns are geographic longitude followed by geographic latitude.

'xx_blocks_angles.txt'
This file shows the length and orientation of the track circuit blocks.
Columns are length (in km) followed by angle (in radians).
Note: the angles are defined such that eastwards is zero degrees with an increasingly positive value for northwards and an increasingly negative angle for southwards.
