If you think only having five minutes on the previous quiz was a little hard, and not enough time – then about about this, a fifteen minute variant over at iknowthetube.com
It’s NOT got the latest 2015 map update with the new Overground stations, but you do have more time to get as many stations as you possibly can. What’s nice about this too is that you get bonuses for getting (say) all the stations in outer-extremity zones, or a whole complete line. You get a total score at the end – separate from the number of stations you might have actually got.
This station master scored 2230 points, with 251 out of 368 stations found. Can you do better?
