split.traintimes.org.uk

This app calculates split ticket possibilities. It is running at https://split.traintimes.org.uk/ but should run locally without much issue.

Requirements

• redis, for the queueing and front page latest.
• python
• virtualenv unless you like installing things system-wide, in which case you should know what you’re doing

Installation

$ virtualenv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

web.py is the WSGI application, you can run this directly with:

python web.py

Which will start up a web server running on port 8080 by default. You can run it via your favourite tool for doing so (I’m using gunicorn, behind nginx and varnish).

You start a backend worker with:

python worker.py

(I’m running multiple ones via supervisor, there is an example config.) And you can monitor the workers with rqinfo.

Updating data

Get some fares and timetable data from http://data.atoc.org/ and unzip each into their own directories, called fare-data-NNN and timetable-data-NNN (with NNN being their respective ID).

Run:

parse-tocs <fares-directory>
parse-stations <fares-directory>
parse-restrictions <fares-directory>
parse-fares <fares-directory>
parse-ndf <fares-directory>
parse-trains <fares-directory> <timetable-directory>
merge-fares-ndf <fares-directory>

And that should update all the JSON files.
