A transition from analogue to digital will help improve maintenance output.
The rollout of digital ALC files across the Iarnród Éireann – Irish Rail (IÉ) OTM fleet is increasing accuracy on key maintenance shifts.
Previously, the process was fully analogue but later moved to ALC measurements being provided on a USB stick which would then be uploaded to the OTM’s computer.
The Automatic Guidance Computer (ALC) is vital for the delivery of accurate geometry on the network as it ensures that the lining, longitudinal level and cross level are fit for the required track speed.
However, an entirely digital system is now being introduced by Iarnród Éireann which will eliminate a series of steps and also help to increase the accuracy and efficiency of the work delivered. Working closely together, Iarnród Éireann and Rhomberg Sersa are testing the cloud-based system to improve output.
“We looked at how to improve the system and make it more streamlined,” said Darryl Gwilliam, Professional Head of Operations and Continuous Improvement with Rhomberg Sersa in Ireland.
“We’ve designed a system whereby Iarnród Éireann can drop files into SharePoint. This dedicated secure SharePoint folder is accessible by the machine, meaning data is available instantly both for download and upload of all tamping files. This makes it less likely to have corrupt files but it also means track designers can make last minute changes if for example, it’s noticed that the wrong data is inputted.
“The second benefit is that the complete post-work file will be sent to the same place and can be reviewed instantaneously.”
By having a repository of data, a picture can then be formed of the network which will assist with the future planning of maintenance work.
During tight possessions for shifts, a digital system is preferable.
The system was tested on one of the tampers and proved successful, with proposals to roll it out to other machines.
