A superelement for the nonlinear lateral deformation of railroad track structures under arbitrary thermal and/or mechanical loads has been developed. The finite element program is capable of accepting any linear or nonlinear lateral and longitudinal ballast resistance properties and any fastener torsional resistance properties. Pre- and post-buckled track deformations can be calculated for arbitrary initial imperfections. Results agree well with published experimental results.
