This project was carried out in partnership with Metro-North Commuter Railroad personnel. Using the manufacturer’s drawings and visits to examples of the commuter rail cab cars in the United States, a design was proposed and developed and a prototype was manufactured.
Working with the Metro-North Commuter Railroad, DeltaRail Group supplied a complete installation kit for a Metro-North Commuter Railroad Shoreliner cab car. The pilot design was installed on a sample commuter rail car.
The significant advantage of the SmartSander over regular sanding systems is the ability to deliver sand safely in every brake step. Not only does this significantly improve conditions for the trains that it is fitted to, but also that much more of the commuter rail system receives regular small applications of sand. This improves conditions for all rail cars that use the route. SmartSander is designed to reduce delays to service, reduce unplanned passing of signals, and increase wheel life by reducing the frequency of wheel truings and reducing the amount of material removed during each wheel truing.
Potential benefits for commuter rail:
Improved safety and stopping during low adhesion rail conditions,
Reduced wheel truing cost overall by reducing wheel defects due to slide events with a target of allowing four re-turns being made over a wheel’s life rather than three,
Reduced sand consumption, and
Improved commuter rail passenger environment due to minimizing noise caused by defective wheels.
Following a successful test with Metro-North Commuter Railroad, the results have been included in the final report for this project and the results will be reported in papers presented to the commuter rail industry by the principal investigator.
The increased adhesion provided by SmartSander operating at different levels of brake demand mean a commuter rail train operator can benefit from significantly reduced wheel damage.
