The snapping turtle rested between the rails of the north bound Amtrak line that rims the Hudson River. If she stayed there, she would be fine, that is, a train would simply sail over her. It must have taken some determination for her to get over the railing—that is the biological willpower of a snapper who wants to lay eggs. But she now looked weary, as if she might not have the resources to get back out. If she loitered on the rails—she’d end up squashed. Another turtle just twenty feet away, lay with its shell caved in, head severed.
