But tonight, heading through the Long Island Railroad (LIRR) space to the subway after the Rangers exciting shootout win over the Penguins, I learned something. On the electronic message board, LIRR announced that in autumn trains on the lines sometimes travel at less than maximum speed because of the "slip-slide" (no Paul Simon reference here) effect. It seems that falling or windswept leaves when they land on the tracks and get crushed by trains slick the tracks with a substance called pectin and cause less adhesion between the train wheel and the rail during braking. The LIRR noted that "slip-slide" is very similar to a car's wheels skidding on an icy road and that it is taking a three-pronged, pro-active approach to resolving the problem.
Ah, "pro-active prongs"-- this decade's "synergy" or "parameters."
