A comprehensive solution to track monitoring and maintenance

Loram is building upon its history of providing the right services to the rail industry with sophisticated expertise in track and infrastructure monitoring technology.

For over 50 years, Loram has been providing rail grinding and track maintenance services to the Australian market. It has become only natural, then for the company to use its expertise in precision rail management to innovate and provide a comprehensive solution when it comes to the interaction of different rail infrastructure assets.

According to Thomas Smith, director business development, cost and consistency are two major issues that are facing rail networks. Having a rich and understandable picture of the track asset can allow for better decisions to be made when it comes to maintenance.

“Having an advanced diagnostic profile of the current health of your track and identifying trends over time allows our customers to migrate to a preventative maintenance program which can save significant money by extending the life of their assets,” said Smith.

Having provided rail grinding, ballast cleaning, and track maintenance equipment and services for decades around the globe, Loram has seen where the gaps are when infrastructure managers are seeking to optimise the upkeep of their network.

“For decades, Loram has had the equipment for repairing and/or maintaining the rail and drainage, including ballast and ditches. Having the ability to know exactly where and how to apply that equipment has been a development process leading Loram to create or acquire the technology it offers today,” said Smith.

This technology has taken Loram’s knowledge of the dynamics affecting track condition and brought a level of precision engineering. For the past 30 years, Loram has been refining its rail grinding through the use of high-speed measuring and analysis, which uses laser camera technology. To analyse track for substructure maintenance, Loram has deployed cutting- edge technology for the last 15 years.

These developments in inspection services have been crystallised into three major areas. The first is rail inspection services, which use rail inspection vehicles (RIV) to collect rail profile, wear, gauge, and cant data. This data is then used to refine a rail grinding program, said Smith.

“Collected data is mapped to exact track locations to positively match the grind plan and applied to the grinder.”

The second area is Loram’s Aurora Track Inspection services. These use imaging technology to scan and reveal the exact condition of below rail infrastructure. Manual detection methods can only detect so much and are limited in terms of the speed at which they can be conducted.

“Aurora can perform inspections at over 65km/h and plays a critical role in prioritising and streamlining our customers’ capital maintenance programs,” said Smith.

Loram’s third area of inspection services are in the field of geotechnical inspection services. These services use tools such as ground penetrating radar and LiDAR scanning technology to measure and analyse geotechnics and substructure. The equipment that performs these scans can be mounted on the vehicle platform most suited to the task, including geometry cars, rail grinders, hi-rail trucks, or other track vehicles.

Taking the results of these services together, Loram can build a solution for a rail infrastructure owner or manager that includes track maintenance as well as formation analysis and remediation. With experience working in many different environments, Loram’s services are able to be delivered in any circumstance.

“Loram hasn’t found a location yet where we couldn’t deploy and manage our services. We recently conducted a geotechnical survey in South America where there wasn’t even rail infrastructure present, only formation. Our technology is set up to be deployed in many situations and can be customised to help meet our customers’ demands,” said Smith.

With the data collected through a combination of these technologies, the next step is to ensure that it is presented in a way that enables actions to be taken and decision to be made. To simplify this, Loram is working on combining data from its various services into a comprehensive track maintenance platform, said Smith.

“The data we collect is technical, time consuming to analyse, and can be overwhelming. That is why the final output that Loram provides our customers simplifies the information into easy-to-understand reports that are customised to our customer’s specific needs.”

With these insights in hand, maintenance can be conducted in a way that uses resources in the most efficient way possible.

Loram’s scanning technology can be fitted to the vehicle required.

“Having the ability to accurately measure the condition of your track assets allows our customers to intelligently and precisely plan maintenance activities with regards to subgrade, ballast, sleepers, components, and rail,” said Smith. “When our customers understand the conditions of these assets and how they degrade over time, then they can take actionable measures to prevent degradation and truly maximise the life of their investments.”

What makes Loram unique, however, is that not only can it identify and monitor issues related to track and infrastructure management, but it has the ability to fix and remedy the issues.

“With all of these inspection and maintenance solutions provided by one company, we have the experience, expertise and historical data to understand how all of the different rail infrastructure assets and dynamics affect each other,” said Smith.

Loram’s own rail grinding and friction management equipment can be deployed to areas of track where defects have been found by rail inspection vehicles. When ballast maintenance is identified as an issue, Loram has an entire fleet of ballast maintenance equipment and geotechnical services that are designed to manage track drainage and quality, or material handling solutions that can pinpoint where extra ballast is needed.

Sleeper maintenance is another area where inspection technology can be used to determine the quality of individual sleepers and components, with the data management to deliver customised reports to the required specification.

“We have this broad range of track data and knowledge from seeing just about any track issue that allows us to help our customers precisely plan, prioritise, and execute track inspection and maintenance on their networks,” said Smith.
