Train of consequences

The whistle blew again and they had to end their embrace. She kissed him one last time on the lips and tried to smile as she let him go. He backed away, waving, then turned and jogged to jump onto the train as it began to steam away. An older couple just near them had gone through the same wistful routine. The old man broke from his loved one too, and ran to leap onto the train, but he had left it a moment too late, and even as he tried to muster a sprint, the carriage door moved just ahead of him. He ran faster than he thought possible, but he was losing ground, and as he frantically tried to catch any handhold he ran over a dozing dog, fell onto a most unfortunately-placed oil slick and slid sideways under the train, the wheels running over and through him, mangling his flesh and bones, rendering him an unsalvageable mess and, to cap it all off, drawing from his sagging rear a huge, noxious grunt and, the subsequent silence suggested, a thick final turd to complete the morbid humiliation.
