Wheel
wear is an inevitable phenomenon on
trains. However the rates of wheel
wear can vary very widely, depending
on circumstances. When a wheel reaches
a certain point in the wear cycle,
it must be either reprofiled by machining,
or replaced. This leads to substantial
costs to the railroad. Typically wheels
are replaced or reprofiled for either
1) excessive flange wear, or 2) excessive
tread wear. One factor or the other
will limit the wheel life. There are
many sub factors within each of these
groups. For example within the tread
wear category are problems such as
wheel shelling (prevalent in cold
weather in freight) and skid flats
(related to poor braking control /
practices).
As in any wear
situation, control of friction at
an optimum level is essential to mitigate
excessive wear rates. This is equally
true for the flange of the wheel (where
as low as friction as possible is
required), as for wheel treads, where
an intermediate friction level is
required.
