The British Rail Fares Engine is a library, API and user interface that can be used to return Britsh rail fares.
It relies on data from Rail Delivery Group. The rules around journey/fare validity are very specific to British rail and are not useful for other data sets.
It does not test the validity of journeys as it has no concept of a journey but it does provide a number of filters that can be applied without a journey:
CalendarRestrictionFilterchecks if the ticket code has any calendar restrictions
AdvancePurchaseFilterchecks the Advance Purchase booking horizon has been met
RailcardBanFilterchecks whether there is a blanket ban on the railcard for a given date
SuppressedFareFilterremoves non-derivable fares that are used to suppress flow fares
TicketTypeDateFilterchecks the ticket type start, end and quote dates

It is assumed that MySQL is installed locally and there is a database called
fares set up. The database credentials can be overriden by setting environment variables
npm run data
Starting the service will load some data into memory (~30 seconds) and then start the service on port 8002. Browsing
http://localhost:8002 will display the test user interface.
Issues and PRs are very welcome.
