Flattened rail - Rail defects
Figure 1: Flattened rail.
Defect name: Flattened rail
Record No.: 2583
Type of defect (Internal/Surface): Surface
Defect classification: Rail defects
Steel name: Steel
Steel composition in weight %: No data.
Note:
Definition - Flattened rail is a short
length of rail (not at a joint) that
has flattened out across the width
of the rail head to a depth of 3/8
inch or more below the rest of the
rail. Flattened rail occurrences have
no repetitive regularity, so do not
include corrugations.
Origin - Flattened rail has no
apparent localized cause such as a
weld or engine burn.
Growth - Individual lengths are
relatively short, as compared to a
condition such as head flow on the
low rail of curves.
Appearance - Flattened rail shows
the following:
• A flattening and widening of
the head for several inches,
with the entire head sagging.
• Small cracks in the depression
on the running surface.
Detection - Flattened rail can be
detected by visual inspection.
