A full return journey is of the form http://traintimes.org.uk /london /leeds /10:00 /next-tuesday /16:00 /next-wednesday.
The time is departure time by default; add an “a” at the end for arrival time, or use “first” or “last” for first or last trains. For example, http://traintimes.org.uk /london /glasgow /first /tomorrow or http://traintimes.org.uk /sheffield /liverpool /11:00a.
You can put “/fares” at the end of any bookmarkable URL to go directly to the fares page for that journey. This will be slower than the non-fares lookup. For example http://traintimes.org.uk/cardiff/bristol/fares.
“/changes=0” at the end of a bookmarkable URL will restrict the results to direct trains if possible, e.g. http://traintimes.org.uk /birmingham /manchester /changes=0.
“/overtake=1” at the end of a bookmarkable URL will also include overtaken trains in the results, e.g. http://traintimes.org.uk /brighton /clj /01:00a /saturday /overtake=1.
