ABSTRACT:
A railway car truck bolster is formed of channel cross section tension and compression members and a reinforced web joined together by welding to form a reinforced I-beam as the primary structural unit for the bolster. The welds joining the main structural elements are disposed to be stressed in shear rather than tension or compression for optimum fatigue performance.
