Mermec Group has won a contract from Iron Ore Company of Canada (IOC) to supply a track measurement system for monitoring the Quebec North Shore & Labrador Railway (QNS&L).
The inertial measurement system will be used for checking the track geometry parameters of the 261-mile QNS&L line, which runs from IOC's mining facilities near Labrador City to the company's shipping terminal in Sept-Îles in Quebec.
Mermec will install a track geometry measurement system based on the contactless technology from an IOC measurement car.
Scheduled to be delivered by the end of 2012, the new measurement system will be fitted on the car's bogie and will be compliant with the main North American standards.
The system incorporates optical sensors that are used for measuring rail profiles and calculates rail characteristic points, while inertial sensors offer a measure of the vehicle's vertical, lateral and longitudinal accelerations along with roll, yaw and pitch rotational movements.
IOC intends to use the new measurement car to perform at least three complete measurements of its entire network every year, between May and October.
Trains operating on the line will be capable of carrying about 24,000t of ore in 240 cars stretching some 4km in length.
