I wrote hubot-national-rail in response to nationalrail.coffee by @JaimeMagee. I wanted to be able to fuzzy-search by station, not by official station codes I could never remember.
You need to set the following:
HUBOT_DEFAULT_STATION
set this to station code of your nearest station (see here for codes)
hubot: trains from <departure station> to <arrival station>
- Show the next trains from one station to the otherhubot: trains to <arrival station>
- Show the next trains from the default station to the arrival station
