Amsterdam Centraal has 15 tracks, 11 of which are alongside a platform: four island platforms with tracks along the full length on both sides (tracks 4/5, 7/8, 10/11, 13/14); one side platform with one track along the full length (track 15); and one bay platform with two tracks (tracks 1/2). Platforms 2-15 have an A-side (to the west) and a B-side (to the east). This means that there are 21 places where a train can be positioned for passenger access, with scissors crossings in the middle enabling trains to pass each other. Track 1 terminates short of the western end of the station building, which fronts track 2. Tracks 3, 6, 9, and 12 have no platform.
