New Jersey Transit has begun its annual fall cleanup operation, deploying two AquaTrack machines to remove leaves from the rails. The AquaTrack equipment, a high-pressure power washing system, eliminates the oily residue left by fallen leaves on the tracks, preventing train delays caused by “slippery rail” conditions.
The phenomenon of "slippery rail" is a common challenge for railroads in the Northeast and other regions where deciduous trees are prevalent. The decaying leaves create an oily residue that coats the rails, causing poor traction and subsequently, train delays.
The AquaTrack system, in use by NJ Transit since October 2003, consists of two 250-horsepower diesel-engine units mounted on a flat car with an operator control cab. The system dispenses water at a pressure of up to 20,000 pounds-per-square-inch directly onto the rail surface, using approximately 17 gallons of water per minute.
The original AquaTrack primarily operates on the M&E and Montclair-Boonton lines, which face unique challenges due to hilly terrain around Glen Ridge and Summit stations. These lines undergo rail cleaning twice a day, Monday through Friday, once overnight and again during midday hours. On weekends, the Pascack Valley and Main/Bergen County lines are typically covered.
In 2016, NJ Transit introduced a second AquaTrack unit to expand its cleaning capabilities, further preventing delays caused by slippery rail conditions. In addition to AquaTrack, NJ Transit trains are equipped with sand-spraying mechanisms in front of their wheels to enhance traction. NJ Transit also proactively trims trees along the tracks to help limit the number of leaves that fall onto the tracks.
According to NJ Transit, the AquaTrack system is a proven solution to a seasonal challenge affecting railroads globally. By using high-pressure washing, NJ Transit is able to remove the oily residue left behind by fallen leaves, ensuring a safer, more reliable commute for its customers.
