Bookmarkable timetable URLs: for example, http://traintimes.org.uk /manchester /edinburgh will give you the next trains from Manchester to Edinburgh.
“n” or “nearest” for the From will, if possible, ask you to share your current location to find your current closest station (uses NAPTAN, Department for Transport data © Crown copyright and database right), e.g. http://traintimes.org.uk /nearest /oxford.
You can put ?via=NAME or ?avoid=NAME at the end of a URL to only show journeys via/avoiding a particular station.
Adding a time, like http://traintimes.org.uk /cardiff /birmingham /8:00, gives you the timetable starting from there. 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.
