In lieu of the changing season, Keolis Commuter Services (KCS) will perform rail-cleaning services on Massachusetts Bay Transportation Authority (MBTA) rail to reduce slippery rail.
KCS explains that slippery rail occurs when leaves and debris fall onto the track. As trains pass, these transform into a thin and slick film that accumulates on the tracks. In these fall conditions, trains are required to begin slowing for stops sooner and take more time to re-gain speed when departing a station. As a result, a train needs more time to travel its route, which can create delays. Occasionally, more wheel maintenance is also required and this can impact coach or locomotive availability.
