Weakened track conditions impacting the tracks buckling potential include: reduced track Resistance, lateral alignment defects, and lowered rail neutral temperature. Track resistance is the ability of the ballast, ties and fasteners to provide lateral and longitudinal strength to maintain track stability.
ballast section based on an assumed bearing capacity of the subgrade (Hay, 1982). Modern track design and the American Railway Engineering and MaintenanceofWay Association (AREMA) Manual for Railway Engineering Recommended Practices suggests limiting the stress on the subgrade to 20 psi (AREMA, 2010). Talbot''s design
Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties.

For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a .
