The alignment of a railroad affects the ride quality most. It is necessary to keep the track irregularities at a bare minimum for safe, and comfortable riding. The significant track parameters are alignment, surface, and gauge. The scope of the paper is limited to alignment tolerance for construction and maintenance. The aim of the paper is to develop a theoretical approach to assess the alignment tolerance of both tangent and curved track for construction and maintenance purposes. The approach is based on comfort criterion on jerk. Currently, there is no such work in literature. Some formulas are suggested for construction and maintenance tolerance of tangent and curved track. The formulas are applied and validated against the current tolerance values from literature, EN specification, federal railroad authority (FRA) regulation, and real-world examples. The paper would offer insights on tolerance values and would be useful for professionals.
