Which structural effect challenged early steam locomotive designs lacking effective suspension systems?

💡 Explanation

When early locomotives traversed uneven tracks, dynamic loading occurred because the unsprung weight and rigid frames amplified the impact forces, permanently deforming the rails. Therefore rail deformation resulted, rather than boiler rupture, wheel slippage, or frame cracking, which would arise from separate mechanical stresses or conditions.
