The coils are on 2mm centers, so the vehicles naturally move in 1mm steps. There are some additional tricks to reduce this step size to 0.25mm for slow running, but they are not shown here. The vehicle magnets must be alternating poles on on 3mm centers, most easily achieved by using 3mm disc magnets.
Here is a simple animation of how these linear motor tracks work. The track consists of three interleaved strings of coils acting as electromagnets. At any time, one string is generating North poles, another string South poles, and the last string is turned off. Any models with suitably-spaced magnets get dragged along.
