Task: Question Answering
Input (English): Passage: As a new Yorker I take the underground , or subway , every day to get two and from work . I always make sure to have my metrocard in my wallet , so if I ever need the subway I can always get on it . I have many station locations memorized , but every now and then I need to consult a map to figure out where to go and where the closest station is .  Once I know I walk towards it , looking for the green globes on top of poles that indicate the station stairs are there and I can enter .  Sometimes I hear a subway roaring through the tunnels and I hurry down the steps to see if its my train .  Instead I see the express train speeding along the center track , because I am at a local stop and still have to wait for my train .  At the turnstile I swipe my card through the magnetic reader and the turnstile chimes and a green led light flashes go , and I can walk through the turnstile and onto the platform .  The train is almost here so I step back and away from the edge and watch as the train pulls in , slowing down and stopping completely in the station . Then I an all the other people pile in through the double doors . There are enough seats so I sit down and the conductor announces the next stop , before the doors closing noise signals and the doors close shut .  Finally getting to my stop I get up and exit though another turnstile and take the stairs up and into a different neighborhood in the city . The underground subway is so easy and fast , its the best way to get around and once you know how , you can go anywhere in the city . Question: When did they see the yellow glow of two train head lights? Option1: when the train got to the platform Option2: While they were on the train.
Output (English): when the train got to the platform
