Concrete ties price evolution. IT04

Dec 31 2024

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.

Railway Books

Jul 08 2024

In this article I present the list of physical books that are part of the bookcase that we frequently consult for the design of Railway Materials. We can find basics fundamentals of the Railway System, as well as characteristics of raw materials, parameters for the platform behavior, interaction with rolling stock, failures, frequent solutions, improvements, and countless number of triggers and relevant information.

The state of the art is complemented with papers, presentations, conferences and consultations. This information is more recent and can generally be found in publications from universities, research centers, symposiums and conferences. Notwithstanding, the act of taking the book in your hand, opening it and turning the pages, exploring topics and sections, undoubtedly represent the starting point of any development process.

Track gauge measuring ruler control device. IT03

Jul 08 2024

Track gauge and cant measuring device are elements for in situ measurement that are moved from the laboratory to the construction site, often together with track tools, along steep roads and are used in conditions other than those of a laboratory. This means that the original certification of the device requires frequent monitoring to remain effective. Likewise, that certification in accredited laboratories can be somewhat difficult due to time, travel and the availability of institutions that carry out this work.

International Railway Equipment Exhibition -IREE 2023. New Delhi

Jul 08 2024

IREE is one of the most important railway fair in Asia. In the fair there are suppliers of railway infrastructure, rolling stock, railway material and components, etc. In the fair there was also a conference where current Indian/Asian railway issues were presented.

Steel bars in prestressed concrete sleepers. IT02

Jul 08 2024

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.

Negócios nos trilhos- NT EXPO 2023- Sao Paulo.

NT expo is the most important railway fair in Latin America. In the fair are suppliers of railway infrastructure, rolling stock, railway material and components, etc. In the fair there is also a Congress where current Latin American railway issues are presented.

Fastener/sleeper electrical impedance test – IT01

Jul 07 2024

The electrical resistance of the sleeper-fastening system in a wet Railway Track is a very important parameter to consider. This is because the rails are electric conductors in the circuit of signalling and traction and, an inappropriate electric resistance may be the cause of many trouble and malfunction. In this first part, it will be studied the origin of the requirement, the conditions in the track and the standard allowable. A second part will cover the test.
