An important difference between four-rail and three-rail operation is
this: On four-rail the centre of a standard gauge wagon, a narrow gauge
wagon and of a standard gauge wagon on transporter truck is the same. On
three rail track, the centre of a standard gauge wagon is 217.5 mm to
one side (= 435/2) it needs more free profile.
Also, the shared rail wears more quickly than the other two so requires
higher maintenance! The four-rail system overcomes this.
