Carriage rides in Central Park resumed Tuesday after a several-day halt, and much backlash, in the wake of the death of an 18-year-old tourist killed in a runaway horse incident last week. Romanch Mahajan, 18, is believed to be the first person to die in a horse carriage accident since the rides were introduced in Central Park more than 150 years ago, according to the labor union representing the industry and the Central Park Conservancy.
