 Grinding is popular all over now, not just on the Heavy Haul lines. Track is
often profile ground in the th suburban area.

 The grinder train often visits the down local on the 'Short' Illawarra line
between Meeks Rd and Hustville, the down local at Allawah in particular is
subject to corrugation caused by 38 wagon coal trains braking for Hustville,
were the coalies not only have to slow for the 'junction' but often have to
stop and wait for a Suburban train to pass on the main.


 The idea is to keep the rail profile matched to the wheel profile. Get the
2 right, and both the rail and the wheels last longer.
