NJ TRANSIT DEPLOYS AQUATRACK UNITS FOR RAIL CLEANING
October 10, 2018
NEWARK, NJ — As temperatures and leaves both begin to drop in the state, NJ TRANSIT is once again utilizing two AquaTrack machines to clean and remove leaves from the rails.
The AquaTrack equipment is a high-pressure power washing system which removes leaves and oily residue from the tracks in an effort to prevent train delays caused by “slippery rail” conditions. The equipment will be used throughout the fall season.
In 2016, NJ TRANSIT unveiled its second AquaTrack unit which allows the cleaning process to maintain a larger coverage area in helping to prevent delays caused by slippery rail.
“The AquaTrack units have had great success in managing leaf-related slippage on our rails,” said NJ TRANSIT Executive Director Kevin Corbett. “By utilizing these two highly specialized pieces of equipment, we can keep , increasing safety and making sure wheel slippage stays at a minimum.”
Fallen leaves left on rail tracks can cause a condition known as “slippery rail” – a challenge facing all railroads in the Northeast and other parts of the world where deciduous trees are prevalent. The decaying leaves create an oily residue that coats the rails and causes poor traction. The decreased train speeds, in turn, create delays.
The AquaTrack system has been in use by NJ TRANSIT since October 2003. It consists of two 250-horsepower diesel-engine units mounted on a flat car with an operator control cab. Two pressure-pump units dispense water up to 20,000 pounds-per-square-inch directly to the top of the rail. The process uses 17 gallons of water per minute.
The original AquaTrack operated primarily on the M&E and Montclair-Boonton lines, which face particular challenges including the hilly areas around Glen Ridge and Summit stations, washing the rails twice a day Monday through Friday—once overnight and again during midday hours. On weekends, the Pascack Valley and Main/Bergen County lines are usually covered. The addition of a second unit in 2016 added cleaning on the Raritan Valley and North Jersey Coast Lines.
In addition to AquaTrack, NJ TRANSIT trains are equipped to spray sand on the rails in front of their wheels to increase traction. NJ TRANSIT also trims trees to help stem the amount of leaves on the tracks. The leaf clearing operation runs from mid-October through mid-December.
