National Rail API

A library to allow simple access to the otherwise awkward National Rail SOAP API.

Installation

Use in a Bundler app. Add to bundler:

gem "national_rail"

Example Usage

The gem is extremely simple to use. There are two class methods that return the next departures or arrivals from a station.

NationalRail::Timetable.departures(token, "BHM")
# => [{"origin":"Longbridge","origin_crs":"LOB","destination":"Four Oaks","destination_crs":"FOK","time":"14:45"},{"origin":"Wolverhampton","origin_crs":"WVH","destination":"Walsall","destination_crs":"WSL","time":"14:47"},...]

NationalRail::Timetable.arrivals(token, "BHM")
# => [{"origin":"Longbridge","origin_crs":"LOB","destination":"Four Oaks","destination_crs":"FOK","time":"14:42"},{"origin":"Wolverhampton","origin_crs":"WVH","destination":"Walsall","destination_crs":"WSL","time":"14:44"},...]

Wrap it in Sinatra

I've used this in a simple Sinatra app. It's easy: 
require 'sinatra'
require 'national_rail'
require 'json'

get '/departures/:crs' do
  NationalRail::Timetable.departures('...', params[:crs]).to_json
end
get '/arrivals/:crs' do
  NationalRail::Timetable.arrivals('...', params[:crs]).to_json
end
