A bit cheeky/sneaky of us to put this one in here – as it doesn’t pertain to the Underground but to National Rail services instead, but it’s the first time we’ve seen it and is kinda cool, so we couldn’t not mention it.
It now appears that for all National Rail stations you can text the full name of the station to 84950 and within a few seconds it will text you back with the next departures from that station.
For stations with more than one word in their name, just type it in without the spaces as one long word. Try it!
