Accessible (& programmable) UK Train Timetables

Matthew Somerville has created a great web application called Accessible UK Train Timetables. For ‘accessible’ read programmable, so that having completed the search form, the resulting page’s URL is useable in another web application in a RESTian way.
for example, my search for early morning trains from London to Bath gives me the following URL:

http://traintimes.org.uk/london%20paddington/bath%20spa/07:30/
