Concrete ties price evolution. IT04

Concrete sleepers represent a significant cost in track renewal construction contracts.

The production of these sleepers is immersed in the general conditions of the economy and the amount of public investment destined for railway. The main variable costs are steel, concrete, and work labor, while the indirect costs are many and highly variable.

In this article I go through a polynomial that highlights these direct costs and some industry considerations to accompany this curve with other indicators.

Concrete sleepers have a certain amount of steel for structural reinforcement, assembly and manufacturing conditions and for the fastening systems. In this article I will review the different functions that these steels fulfill in a concrete tie, what type of steel they are and some constructions practices that allow us to understand the reason for certain reinforcements. The article refers to the sleepers that currently exist in Argentina.
