To increase the resistance of plastic and/or plastic composite railroad ties
tosliding
within the ballast of the railroad bed, for example, sliding lengthwise (in the
direction of the longitudinal axis of the tie) and sideways (in the direction perpendicular
to the longitudinal axis), ties with a textured surface which aids in anchoring
the ties within the ballast of the railroad beds. In particular, the ties are provided
with a pattern of indentations within a surface that contacts the ballast which
increases the ties resistance to sliding. The pattern is molded into the ties so
as to mechanically interact with the ballast (rocks) and provide as much resistance
to sliding as possible, especially along the longitudinal axis of the tie but also
in the direction perpendicular to the longitudinal axis.
