Leaf Laser.
Metro-North Railroad BL20GH no. 130 (Brookville, 2008) - sporting an unlettered CTrail paint scheme - is seen shoving the railroad's "LaserTrain" south through Marble Hill, Manhattan. Ahead of the locomotive is the star of the show, Comet III car 5010, which is equipped with laser technology that eliminates leaf residue on the top of the rail, which reduces friction and can have adverse effects on train braking and acceleration.
