"The LIRR currently uses two M-1 cars to "slime" the rails during falling leaf season. Modified M-1's 9401 & 9591 (now E-401-591) are utilized sandwiched between a pair of MP15's.They operate entirely at night and are serviced at Richmond Hill during the day.
There are also leaf crusher trains. These consist of two MP15's and gravel hoppers. They crush the leaves on the Oyster Bay , Pt. Jeff, Montauk, and Greenport branches. These trains are based at KO and Wellwood siding and operate at night."
Both sandites and leaf crushers have run on the branch simultaneously, and have been on the branch with both. Leaf crushers are operated on the branch to pulverize leaves that may be wedged in the circuits for the crossing gates. If leaves are not crushed, the potential for leaves to impede a circuit and crossing gates to stay up while a train goes through a crossing increases. All leaf crushers are run at the direction of the train dispatcher. Information courtesy: Ben Jankowski, Oyster Bay RR Museum
