Station 5

You are trapped in an underground subway. Observe your surroundings carefully and take the correct trains to reach the 'Station 5' and exit the subway. You start at Station 0, waiting for trains. When each train arrives, get on that train and inspect it to see if you can find any anomalies inside. If you find any anomalies, leave that train and wait on the station for the next train. If you don't find any anomalies, take that train to the next station. If you take the train with anomaly, that train will take you back to Station 0. If you take the train without any anomaly, that train will take you to the next station. Take the correct trains to reach 'Station 5', where you will have the exit available.
