The station has three tracks with platforms numbered 1 to 4, the centre track being served from both sides by platforms 2 and 3. This is an example of the so-called Spanish solution. Most eastbound Piccadilly trains terminate here, although some terminate at Arnos Grove or Oakwood, particularly in peak hours or in the evenings. Some trains may even terminate at Wood Green; however, this is only used very early in the morning or in emergency situations. Cockfosters depot is located between Oakwood and Cockfosters and trains can enter or leave it from either direction.
