Autumn is a favorite season for many, including railroaders. Weather and temperatures are usually milder than other seasons, and the colorful leaves on just about every tree are a sight to behold. However, when those beautiful leaves start piling up on the surface of rail, and rainfall mats them down, all of it turns into a big mess. So much so that operations of the Long Island Rail Road (LIRR) can be significantly delayed. "Like other railroads that operate in seasonal environments, the LIRR experiences leaf fall-induced low adhesion," Meredith Daniels, spokesperson for LIRR, told RT&S. A slick substance, called pectin, left by crushed leaves on their rails that get even more slippery after it rains, creates this condition. When a train attempts to speed up or slow down, the pectin can cause the wheels to slip or slide along the rails. In severe cases, the train will automatically make an emergency stop, because the on-board computer system perceives "slip-sliding" as the train not slowing down when it should.
