Trains are typically made up of multiple carriages. The axle counters ensure that all the carriages which enter a section of track leave that section of track, and that none have detached and been left behind for the next train to run into.

So while the train is within that segment, the value of the counter is non-zero. Once they exit, all the axles should get counted again in the opposite direction and reset the count to zero. The problem with 256 is that the count would be at zero while you were in the track segment.
