Hmm - wasn't even aware that this info was available!! Doesn't look like there's a way to access it without screenscraping the TFL website though. If you have to download the whole page anyway and then screen-scrape it to display the info you might as well just access it from the browser - so no benefits from a data transfer perspective.

It would be trivial to make a client app to enter your query and then display the result page. At least save some bandwidth.
