Up to 22 LRVs operate daily on the standard-gauge, double-track network which comprises two lines with 23 stops. During the peak period, LRVs operate at three-minute headways.\r\nThe audit was conducted between February 9 and February 22. Different measuring procedures and techniques were used to create an overall picture of the current condition of rails and track, and the data was evaluated using high-performance software developed by Vossloh.\r\n\u201cTo be able to inspect all of the 52km of rail during the short night shifts and digitally record the rail defects or parameter deviations, we had to plan the simultaneous deployments of the teams as precisely as possible,\u201d says Mr Emmanuel Ettighoffer, Vossloh\u2019s project manager. \u201cIt therefore proved helpful that all the profile measuring devices and material testing equipment are manually guided and can be on-railed and off-railed quickly.\u201d\r\n\u201cOn a day-to-day basis, the network\u2019s quality is assured by our own maintenance technicians, but after five years of operation, and in order to obtain a precise and global analysis of the rails\u2019 condition, we decided to work with Vossloh,\u201d says Mr Eric Lang, CTPO\u2019s contracts and technical project manager. \u201cThe analysis will allow us to implement an individual and efficient maintenance strategy.\u201d\r\nThe results confirmed the assessment by CTPO that the track is in good condition. \u201cIn addition to the feedback provided, we were also able to draw useful conclusions from the analysis about the wear behaviour of our rails,\u201d Lang says. CTPO wants to apply data to optimise the maintenance cycle and to make more targeted use of the maintenance budget.
