To elaborate on this, I think what is going on is a section has a "counter-upper" on one side, and a "counter-downer" on the other side. 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.
