If you gave me nice new trains like the ones on the L line — instead of these 40-plus-year-old dinosaurs — maybe I’d be less likely to chuck my chicken bones any which way:

Wet, sticky spots on the train floor, chicken bones, nut shells, spilled coffee, hot dogs and “lots and lots of rolling bottles” often greet subway passengers who travel on the E and the Q trains — rated the dirtiest lines in the New York City subway system in the latest survey by a rider advocacy group.

Riders on the L line, however, are getting the cleanest ride, according to the group, the Straphangers Campaign, which released its findings on Tuesday.
