A world of knowledge
Metro North, New York
MNR and LIR chose the Pandrol Automatic Inspection System (AIS) WheelChex®, which consists of 32 Pandrol MultiSensors™ in each of four tracks in the Park Avenue Tunnel under Manhattan; a total of 128 sensors per installation. The WheelChex® system, powered by Pandrol sensors, has been so reliable that Metro-North has selected Pandrol to deliver three ‘Train Fault Detector’ (TFD) houses, adding hot wheel and bearing detection, along with enhanced data analysis. This was a ‘first’ in the US rail transit industry in combining these measurements into one location.
Pandrol’s innovative TFD system provides a comprehensive overview of wheel and axle condition and will allow the railroads to benefit from operational information in the form of messages and alerts to tell them if a particular vehicle is presenting a risk to the infrastructure. With new trending algorithms, this makes it possible to plan ahead and avoid some of the panic that happens when leaves fall on the line in autumn, when most wheel damage occurs.
